Western Digital Hard Disks - Which to buy? WD Blue, Black, Purple, Red, Gold and Ultrastar.

[@carlosedwardos]

This is better content than the channels with millions of subscribers, you saved me a lot of research time, and confirmed my findings - Well done, Sir! - I was trying to find the most reliable drive, as I am notorious for not backing things up as I should, and I also wanted good bang for the buck, this video answers both of those and reaches the conclusion that my minimal research came up with, causing me to feel much better about my preliminary selections. You also kept me from wasting money on WD Gold and WD Black. Bravo! - Your channel will eventually go viral if you keep this level of good work up, just look at what happened to channels like Gamers Nexus or Bald & Bankrupt - They just caught fire eventually and blew up to several million subscribers overnight!

I came across his content only recently and Ive already learned some important things to look for in hard drives. This channel should catch on if enough people see it.

[@BoraHorzaGobuchul]

Please note that Ultrastars can be SMR too. Namely, 20tb DC HC650 (seen at 12:13 in this video) is, unlike the 18tb DC HC550, SMR according to the manufacturer's website: "The Ultrastar DC HC650 20TB HDD with host-managed SMR enables the highest capacity HDDs for data centers. Media tracks are overlapped (or ‘shingled’) with adjacent tracks" 0F38755 \ DC HC560 is the 20tb drive that has CMR. Honestly, somebody should pass a law that they should write SMR\CMR in big red letters on the drive label.

[@sometechguy]

The DC600 range is host managed SMR though, so this isn’t something you could accidentally buy. This requires that the host system can manage the drive. This is difference to DM-SMR (device managed) that we have seen on the Red and Blue drives.

[@Vednier]

Speaking about Purple drives, there s one dditional thing - its main difference 1) they came from factory with head unloading disabled, they dont go to sleep on its own 2) they support Streaming feature set. Its special set of commands allowing drive to drop pending writes or ignore write errors IF this mode was requested by host. This allow drive to increase write speed sacrificing some of write reliability because one damaged frame doesnt make difference. There is not much of info on how its is implemented really but some people raised concerns on should be Purple used in not video-capturing systems. WD however claims its fine.

[@Matlockization]

You're completely right about WD being vague about the specs, however you can apply this idea to just about any electronic device where the manufacturer are claiming it's 'better than the rest'. That's why if after digging I get no answers, then I go elsewhere. It also helps to read the reviews if they are available.

[@PatrickDKing]

I used to buy all HGST Ultrastars, then for whatever reason distribution sucked and it seems only odd and end places or shady resellers have them available. So I decided to just get WD Gold drives exclusively now since all the major distributors have them. If you are patient you can get them cheaper than any other the other drives and lower cost per TB. My sweet spot is about $270 for an 18tb WD Gold drive here in the USA. I almost got some Ultrastars but after digging around found out they were "recertified/refurbished" whatever the hell that means and by whom I don't know. Not going to risk it to save a buck on my mission critical stuff. I won't pay normal Gold prices those because those are horrendous.

[@sometechguy]

You should be able to find WD Ultrastars ok, and those are an evolution of HGST unit, and are also basically the same as WD gold under the hood. I did a comparison of the larger capacity enterprise disks based on BackBlaze reliability data and they seem really solid.

[@eliotcougar]

One note on WD Blue drives in comparison to Red drives if you plan to use them 24/7 in a NAS... Blue drives tend to park the heads way more often, thus wear them out quicker... Red drives always expect data to be read or written I guess, and don't park the heads at every opportunity... The only difference of Purple drives is the support of Streaming instruction set that is used exclusively by specialized surveillance equipment and nowhere else…

My 16TB EXOS has been running 24/7 nonstop for more than 3 years without any problems but they are kind of loud. My 12TB WD Golds has been the same too and much quieter but it's more expensive. One of my HGST 4TBs got corrupted a few years ago. The other 4TBs and 8TBs are still doing fine but they are not being used as much now. I've tried 16TB refurb Seagate EXOS from Amazon and they are running great. I might take my chance and go for the same for my new 8-bay NAS in raid 6. It gets expensive real quick when you fully populate a NAS. 😭

IMO there is no possible reason to buy anything but the Ultrastar - MUCH higher reliability in any usage.

I agree, and research heavily before buying. Hope this video helped some with your research and welcome to the channel. 👍

[@amarokorama]

5:48 "5400 RPM Class" = actually 7200 RPM, but somehow dumbed down in firmware. Meaning you get the power consumption, heat, noise of a 7200 RPM drive with the slower transfer speeds of a 5400 RPM drive. Great job, WD. You can find some forum discussions and even news articles about this, e.g. on arstechnica, "Western Digital is trying to redefine the word RPM".

[@sometechguy]

Thanks for this pointer, that’s interesting. This is again disappointing for WD, they never seem to learn how this negatively impacts customers opinion of them, and not sure they are even doing this, just call it what it is with the lower rate. Or use a 5400rpm platform.

[@rangersmith4652]

I've had WD Red Plus 3TB CMR 5400rpm drives, six of them, in my home file server since 2015. All are running fine after more than tripling their warranty period. If I ever need to replace any of these I'd probably buy Red Pros. I have a pair of WD Black CMR 7200rpm drives that are almost as old and also still going strong. Over many years, I've had about 30 different HHDs from all the current brands, and the total number of HDD failures I've experienced is still one. That was whatever was in my Dell Inspiron 6000 laptop. It was pretty much garbage from day one, as was the entire machine.

[@ManuFortis]

Thanks. This made it all a lot easier to just buy the right one I need instead of having to dig through ALL that data myself. Basically get the Ultrastar 20-24GB models. I generally just use SSD's now, but I can't deny the usefulness of a generally reliable hard drive for cold storage. Solid state stuff is nice and all, but the reliability is kind of touch and go. I will NOT be buying any more WD SSD's in the future. Have 3, two are failing faster than they have any right to be despite adequate cooling, and the 3rd one was barely used so it's still fine. I use only the Optane line up and Samsung Pro's now. Costs more, but so far, worth it. But even so, they only hold up to 2-4TB in the best case scenarios; and aren't exactly cheap for it either. So a good set of HDD"s can be real nice to have even if they aren't plugged in all the time. Or have them setup in some NAS box in a raid array that only gets accessed mostly to write to, rarely read except when actually needed. I do wish they had longer warranty's on these drives though. Not from expecting or wanting to have to use them, but because it's not exactly incorrect to base the potential reliability of an item based on the warranty period they are willing to toss in for 'free' as part of the products sales pitch. For instance, you gonna buy the PSU with a warranty of 5 years, or 7, or 10, or even 12 years? Personally I go with the 10 or 12 year warrantied ones when the sale is nice. Can basically guarantee the PSU should not be an issue for at least half that life span, kind of... and then have another 5 years or so of 'probably will be just fine' life span before the final months where I should probably get a new one and set that one aside for emergencies.

[@sometechguy]

SSD and HDD bring different value. A time will come when these spinning drives are gone, but until the cost, reliability and long term endurance catch up, they will have their purpose. And yes, the Ultrastars appear to be great drives, at least from the data that is available from disks that have been running for an extended period. The price gap is also closing with Seagate.

[@wngimageanddesign9546]

I avoid SMR like the plague. Terrible hit to performance, even for saving files. WD Ultrastars are fantastic and that's due to them being rebadged HGST enterprise drives. Seagate has higher failure rates, also has SMR issue. And as for Toshiba, they suck, far more failures within 4-7 years. BTW, great videos!

[@guessundheit6494]

In all these videos and web pages talking about "how long will your hard drive last?" they're always referring to drives that are being used. What I want to know is how long an unused drive will still work.

[@sometechguy]

HDDs on the shelf will last way longer than SSDs as the data doesn’t degrade naturally like SSDs. However bitrot is a thing so data can get damaged over time and starting up the disk now and then and performing some kind of data integrity check is a good idea. It will vary, but to give you an idea, 10years is the kind of number you could think about, but occasionally doing a full data integrity check and fixing errors before they broke unrecoverable would extend that. YMMV

Now that I'm in the market for >14TB drives at home, the big question is noise - everything got louder after 14TB. I want low noise, including at spin up (or disabling sleep + spin up). What's the right choice for 20TB, 22TB etc … Purple Pro or Red Pro ?

[@jacobp7289]

Having 20 hard drives of various brand and models I can say that theres no good reason for not just buying Seagate Exos or WD Ultrastar which is mostly the cheapest pr. capasity. Paying extra for Ironwolf or RED is a complete waste of money.

[@sometechguy]

This is my assessment also, because for some time the enterprise disks have been cheaper per TB. If that changed and they cost less, I could change my mind but I would stick to the Pro versions which are very similar disks. The Ironwolf Pro's do come with data rescue services, but I wouldn't want to rely on that anyway.

[@Seujiro]

Nice video, thanks a lot. So, do you think an Ultrastar or are Red pro are similar to a WD BLACK right? without the overprice.

[@sometechguy]

The black may be a little quieter, as the firmware is more tuned towards that and less for performance and 24x7 running. But from what I have seen on the drives, it’s likely the same platform/hardware with some firmware changes. NAS and enterprise will sleep less often, though you can set lower save settings, and maximising performance often means more aggressive seeks, which makes the drives a little louder. But personally, I would compare pricing and if the Ultrastars are the best price per Tb, I would go with that. The prices may vary, but often the Red and Blacks are more expensive than the Enterpise drives.

I went through specs of all listed and watched some other noise level clips but all seem quite loud. Could you please advise?

[@sometechguy]

The higher end drives typically have the higher performance and warranty. But they are also noisier, the noise is mostly related to head servo noise, and to get best performance, those are more aggressively tuned for higher performance so people comment on the noise from enterprise drives. NAS drives seem to be a little quieter, so maybe a Red Pro is a good balance but these NAS drives are often not the best value. So you may need to choose what is most important to you, noise or performance/warranty coverage.

[@sometechguy]

I have not heard of any issues with Helium leakage, many reports of drives beyond their warranty and still reporting 100% on the helium content. Also, air drives are actually not sealed and it seems particles getting past filters and causing head impacts is a real thing that helium doesn’t suffer from. Maybe this is worth some analysis, but it seems that helium drives provide better reliability than air filled variants. Of course, YMMV and there are always outliers.

I compare prices here in the UK often between the high capacity enterprise drives (18-24Tb) from Tosh, Seagate and WD to catch bargains and prices do seem to vary fairly often.

Since I don't game on any desktop I have made, is it okay to use an HDD in a computer build that I would use for everyday tasks like I've always done?

[@sometechguy]

Having an SSD as the system disk will make it a much more pleasant experience. It will boot a lot faster and load software and other files much faster. So I would recommend an SSD, ideally an NVMe disk for the boot and system disk. But it probably depends exactly what you do with the machine and what capabilities the motherboard has. But you can use a relatively small and cost effective SSD for that, and use a HDD for storing large data.

[@Vednier]

Hybrid SSD + HDD system is most balanced scenario. NVME is great addition but its performance gains depends on amount data your system reads in one go, still its not bad idea to get one if you have place where to put it. I was hesitating far too long to use SSD as system drives and difference is very visible.

I couldn't find a HC510 for sale easily, but if I compare the 12Tb HC520 and the 16Tb HC550, the price per Tb for the 16Tb drive is maybe 20% better. The data I have seen suggests the newer (larger) drives are also a little more reliable. So personally, I would pick the 16Tb.

Very nice overview, especially of the confusing WD range, thanks! I think that you have overblown the SMR issues a bit and are dinging WD more than they deserve. I remember this issue when it was discovered, and I think that it was murder on ZFS but not really an issue on other file systems. And once WD saw the industry reaction, they got religion on disclosing the recording type, making it easier for customers to make the right choice. I'm running all WD drives at the moment, all CMR, and not having problems. Also, UK prices are awful compared to the USA! Is this VAT? Or just capitalism run amok?

[@sometechguy]

Thank you! For me the SMR instance had three dimensions. Firstly, they did not disclose the change transparently. They were not alone there, and all the major manufacturers put SMR drives into their lineup without good disclosure. For example, the sustained write performance numbers are typically maximums and do not measure the impact once the write buffer fills and SMR has to start managing the rewrite of zones into its throughput. Secondly, WD were the only one to put this into a NAS drive, and the issue wasn't specifically for ZFS, but really for any RAID implementation, which is really what NAS drives are for. Maybe less so during normal operation, but terrible for rebuilds as the long term write performance was significantly worse, causing disks to be ejected from RAID arrays or for rebuilds to take far longer, or to fail. And thirdly, when pressed on the issue they declined to admit it for some time. People contacted WD support and asked, and were not given an answer. This is how it really became the issue it did in my opinion. Mistakes get made, and its how you show up in response that really speaks about company culture. WD did not show up well. So I think they do deserve the backlash, and as a customer, I can only hope lessons were learned. Though subsequent similar failures suggest they didn't learn a lot. But that's just my two cents. 😎 As for UK prices, it varies but US prices have often been better across many market sectors, especially technology. Any UK retailer has to price with sales tax (VAT) included, which I prefer to the US system where I really can't tell what I will pay without doing some math. And UK sales tax is 20%, so this doesn't help, where it can vary by state in the US. However, prices can vary and be better here based on current exchange rates etc. What was interesting to me from looking at the prices is that the Blue drives actually represent a lower price point per Tb than the higher end drives in the US, which didn't hold true in the UK. Given that the drives have lower performance and warranty cover, if you can live with some of the enterprise drive characteristics, such as power and noise, a pro/enterprise grade disk is better value here. Of course things change, so it may not be the case in 3 months, but if you are buying, its worth checking that situation at the time. Thanks for dropping by, making a reasoned comment and sharing your view. I appreciate it.

They were discontinued about 9 years ago.

Thank you

Ridiculous how much more expensive they are in the UK If you need a few of these it'll probably be cheaper to import them

I have never had an Enterprise drive fail. They are worthy of the price. AVOID SMR drives

[@Seujiro]

Hi again: may I ask you something again? I can get an new WD Ultrastar DC HC530 14 tb SATA hard drive al the same price than a WD BLACK 6TB. The main use is for PC use and backup information; movies, fginished renders and all that stuff. Dou you think it is worth? My motherboard is a b350 Asus aRog Strix f gaming and I have a 750w power supply, PYLON. I ask you because I adon´t want to buy before being secure.

[@sometechguy]

The motherboard and PSU shouldn't be a problem. Power draw for the black and Ultrastar will be similar and sata HDD do not draw a lot of power, 5-10w. I personally would buy the Ultrastar, especially if you get more for your money. Comparing the two, the Ultrastar would give you a little extra throughput performance, but there isn't much in it and you don't buy HDD for high performance compared to NVMe or even SATA SSD. The Ultrastar will likely be a bit noisier, as most enterprise drives are and the default for power save may spin the black down sooner as its a desktop unit, but you can adjust power save settings. But in many ways, they are similar from a hardware perspective, most of those changes are in firmware. The Ultrastars are great disks, and though the blacks are good as well, they are often overpriced.

[@Seujiro]

@@sometechguy ok thanks a lot. That 14tb new hdd Ultrastar costs me 150 usd and the WD Black 6tb costs the same, so, there is the answer. The Ultrastar gives me more for my money. Now, as I told you, I will use it for backup; movies, documents, finished renders and all that stuff. In my Pc I have a 2 tb predator mx7000 nvme, 1 tb Adata su800 ssd and I will add the Hdd. Now, I didnt undestand you very much about the noise and energy. Do you use pone configuration for that? Thanks a lot dos your answer, i think this kind of info helps a los people un choose a good component without overprice and just marketing.

[@ajt_channel]

Hi, do you have any recommendations between the Ultrastar Air filled drives vs the Helium filled ones? HC330 vs HC510 for example.

[@sometechguy]

For the larger capacities, they are typically going to be helium. This is true for most manufacturers for 14Tb and up, but there are some smaller drives. This is because helium fill reduces turbulence and the related heat generation and this problem gets bigger as the platters get closest together, which happens with more platters. But other than this, and that power use and heat production are greater on air filled drives, I wouldn’t worry too much about much about this. The warranty is the same, but the expected MTBF is improved on the later model, also Ultrastars appear to be good drives but the AFR does seem to be improving on later models. So the larger drives are probably better, and cheaper usually per TB. But if you only need a 10Tb drive, then the HC330 is going to be a good drive with a lower unit cost.

[@rodfer5406]

[@aleksandarkikivideos]

Hi, can you tell me is it safe to use RED PRO or GOLD hard drives as a single NTFS drive in a PC for data storage? Does it have some drawbacks beside noise? I am in search for most reliable 20TB drive and I don't want to use NAS

[@sometechguy]

There should not be any problem with this at all. And if I was buying a large capacity disk for my PC, i would be looking at these disks if the price per TB was right, which it has been pretty consistently. Other than the noise, the firmware won't be as aggressive on parking the heads or power saving because for NAS / Data center use cases, power save isn't as useful as the disk would constantly be asked for access again. You can configure power saving to put the disk into power save, but I wouldn't do this too aggressively as its probably better for the drive to leave it to its thing. Unless you are really trying to optimize power. And on that note, there is likely a slight power increase for those drives, in the region of a watt or two.

[@DocBain1]

I will never purchase another Western Digital drive. Back is the 90s when I built PCs for people as a second job, Western Digital drives would crash, sometimes without warning, within a year of placing into service. Last year, I purchased a new MSI GE76 laptop with a 2GB WD Black M.2 SSD. The drive crashed with no warning after 14 months. I was unable to retrieve my data after it failed. No more Western Digital for me.

[@MrStevenAttila]

Hi! I have a question. What are the differences between these categories such as enterprise, or surveillance? Not all can be used on a simple PC? Or are these only names?

[@sometechguy]

The drives are largely based on the same platforms and components, but there are physical improvements on the higher models, such as better vibration sensors etc. However, most of the differences are in firmware, which is the code that programs how the drives work. Broadly speaking you can use any drive in a desktop PC, but enterprise drives will usually have better performance but will be a bit noisier and use more power, they will also go to sleep less often though power saving can be configured in the OS. But you can use any of these drives in a PC, and aside from a bit more noise, the higher end drives will have better warranty and will usually perform better, and as I talk about in the video, may not really be more expensive.

[@MrStevenAttila]

@@sometechguy I understand, thank you for your help. 🙂

[@TecraX2]

TLDR: If you want a larger drive, just buy an Ultrastar!

[@Vednier]

My queston is - previous anyone was able to identify SMR drive by its cache size - its usually 256Mb vs 64 in CMR. But now we see drives like WS40EZAX with 256Mb cache and claims to be CMR. Some newer CMR drives even advertise TRIM support. How it is possible? Why CMR drive uses big cache? What TRIM can even do on CMR? Are they blatantly lying?

[@sometechguy]

This is really interesting. Is it possible the larger cache and TRIM support is there in support of their AllFrame technology? Writing streaming data may be more efficient if the data can be buffered in cache in larger chunks, and then written sequentially rather than writing many streams in different locations at the same time. And maybe TRIM is there to help with cleaning up when data is overwritten. This is worth of a deeper dig. And with disks getting larger, large parallel file writes are not going to just be limited to streaming applications, there is quite some effort to wring performance out of spinning disks. I couldn't totally exclude some misdirection on the recording technology, but I would think it would be very risky to misstate this clearly in documentation. They suffered a class action as a result of the SMR drama before, and this would be far more egregious. There is also the subject of storing more drive metadata off the platter and on cache or nvram to help with performance there also.

[@Vednier]

@@sometechguy Well, SMR use TRIM for its zones optimization (internally its moving data around much like SSD do, rewriting from CMR disk cache to slow SMR zone). TRIM on CMR would imply its SSHD, but isnt they all extinct? Even if not, TRIM issued by OS, so to use NAND part of drive as cache there is heavy need of proper support of that by OS, i didnt seen any mention of that by WD. Speaking of Allframe, yes, large cache can help with writing videostreams, but i had feeling its more about ATA steaming and optimization to parallel writes. I have WD40PURZ and its have 64Mb and no TRIM support, while also advertised as Allframe. Heck, when i was purchasing i got exactly this model because it was 100% CMR while models with larger cache was actually cheaper. I have slight fear WD is still wanting to switch everyone to SMR one day.

[@Vednier]

@@sometechguyThere is some reddit posts about this, searched for "WD43PURZ TRIM" - people found Purple drive featuring TRIM. WD support given very vague answers about this topic directing on some white paper about how TRIM can benefit HDDs (bit funny enough its paper about SMR drives). So, its very inconclusive. Its possible its just firmware stub doing nothing in respond to TRIM. Or not?

[@sometechguy]

Thank you, you came with some really interesting info here. I will check in on that thread and dig deeper on this. There do appear to be a new generation of Purple with superficially very similar stats, but with different model numbers. So something is going on.

[@TheShorterboy]

awesome

[@WantedByCod]

Yo, I requested a custom build from a pc shop i got a 2tb 256m wd blue but they called me a said they ran out of stock and i won't be able to give the requested drive and they'll replace the hdd to a wd purple 2tb 64 with no extra cost, will it affect the pc performance negativily?

[@sometechguy]

I wouldn't think so, but will depend on exactly what drive models they are. But the Blue drive is likely to be an SMR drive, which will have poorer write performance on large writes, where the Purple has its cache usage optomised for writes, and won't be SMR. Overall, the purple drive is likely going to be the better drive, but will depend a little on what you use it for. Hope this reply doesn't come too late for you, and good luck with the PC.

[@LegacyIvyTerascale]

red toshibas dont work vertically, only horizontally

[@sometechguy]

There should be no problem with the way the disks are oriented, though I would not change the orientation while they are spinning. And just for clarity, what did you mean by 'red toshibas'? this video was about WDs, though I have others that cover Toshiba and you may have been referring to one of them. And the 'Red' disks are made my Western Digital.

[@Longjumping-War2484]

I'll tell you right now the wd enterprise gold drives are the best, bar none!! That's from experience! Check the specs!

[@Marco-rn8lh]

What manufacturer and Harddrive would you recommend for SAN/NAS Storage?. I watched all your Videos but now i am not really sure what to buy 😅

[@sometechguy]

Thanks for watching, and I think the answer does depend on what you need. What size NAS do you have, and approx how much storage space do you think you will need? It will also depend on the prices where you are, but the Ultrastars are a great choice currently, but Toshiba and Seagate may also be a fit depending on prices. Happy to give some ideas with a little more background. 😁

[@Marco-rn8lh]

@@sometechguy I am an IT administrator and currently planning a new NAS and SAN environment. While searching for new hard drives, I came across your videos. I found the data and information from Backblaze very interesting. Price is not a concern :-) the most important thing is very good reliability of the hard drives. They should have a low failure rates. In the end we would need arround 300-400 TB in total 😄 So every hard drive should have more than 10TB

[@sometechguy]

I have another video that compares reliability data from each of the manufacturers (you may have seen it) and the WD Ultrastars have been very solid over the last 10 years or so. I can't say for sure they won't release newer drives with issues, but its a great place to start. There is some hard data on some capacities that fit your profile, but you would reasonably extend that to drives of higher capacity in the same product line, especially given the long term reliability trends on the Ultrastars. The larger capacity models probably offer the best storage density as well as price per Tb. Large drives take less bays and provide more flexibility for scale up. kzbin.info/www/bejne/n5Sxk5iujrtmg5Y But I don't really believe in telling people what to buy, as there are many variables such as price, availability and possibly support in different places. But I do try to provide the info to help make an informed choice. Hopefully this all helps, and thanks for checking out my channel.

[@Marco-rn8lh]

@@sometechguy Thanks for the information. We will check out the Ultrastars ☺️

[@dangingerich2559]

There are Toshiba hard drive fans? How? I've only had horrible luck with them, and that's in 10 years of desktop support and 15 years in server storage administration. Why would anyone be a fan of them?

[@sometechguy]

The analysis of the backblaze data, which does only contain MG07 and MG08 Toshiba Enterprise drives, but it's around 56,500 drives as a sample size, shows they have good reliability. And when I have made videos about Seagate and WD, there are usually quite a few comments from Toshiba fans questioning why they don't get more focus. But for sure, the variety of models and the total drive count provides a smaller sample size to analyze than for WD/HGST and Seagate. So it looks like there is quite a fan base, even if their market share of the HDD market is only around 18% or so. And unlike Seagate and WD, there are far fewer comments slating them for being bad. But again, smaller market share so probably expected. 🤷‍♂️

[@StefanHolmes]

Are gamers even considering a hard drive, these days? I’ve been using SSD’s for more than a decade and only the smallest games (often much older titles) would load from a traditional hard drive in a non-frustrating amount of time. I do have a few titles in my Steam library stored on a NAS, but practically all games should be kept on an SSD for a good experience.

[@sometechguy]

Yes, for sure. NVMe for boot disk and for games libraries, maybe an SATA SSD and spinning disks are great for mass storage like media.

[@johncrighton4738]

Your JUST reading specs! You have no clue of the internal features of the different types, THIS IS WEAK

[@Igorath]

seagate remains the better choice? hmm tell that to my brand new portable seagate hard drive that died after 3 hrs of use with my computer's back up on it right after i wipes the desktop's hard drive. your credibilty is down the toilet.

[@sometechguy]

I think you may be referring to me saying that in a previous video I compared Seagate NAS and Seagate enterprise, and that between those, the Seagate Enterprise drives were a better choice. This wasn't a comparison between Seagate and WD. I do have a video about that, and though it isn't as simple as one is better than the other, my findings there are that WD generally produce more reliable drives.

[@0bsmith0]

No WD products.

ALWAYS EVADE SMR IT IS GARBAGE

[@sometechguy]

I agree, I am salty about the SMR history. The technology isn't 'bad', but it has upsides and downsides and I think this wasn't well communicated so expectations were not set properly. But that said, I believed there is continued work on improving SMR, and there are device managed and host managed versions of this, so maybe things will develop in this space. I just hope the 'customer feedback' that happened over the last few years changes some attitudes about the transparency of this technology to users.

[@manojkumarbehera9712]

Hi , i am a movie lover. Always Stores movies in my pc . Further I am thinking to buy a 10 tb surveillance wd purple hard disk for my pc. Is it a good idea. Need your help.

[@sometechguy]

The purple is a perfectly good choice for this. The current purple range doesn't contain any SMR drives, but the capacity only goes up to 8Tb, so for 10Tb you are looking at a pro disk, which is also a great disk. Your use case is not a demanding one, so most of the disks would be fine, though I would generally avoid SMR. So check which of drives gives you the best price per TB, and you would be fine for what you need.

[@starkfuture1057]
