The most infuriating part of that submarining of SMR into RED line is that they pushed it onto older models that never had this option before, so replacing failed drives in older RAID arrays is dangerous.

I have 4 3tb WD reds from back in 2013 i got 4 more for a RAID 6 i wonder if they switched to SMR during the run because all 4 new WD Reds i got in 2019 would not play nice with my LSI RAID card ERRORS ALL OVER!!!! I had to return all 4 drives.. so SMR was a complete FAIL! and wasted my Fing time... i will tell you 100% SMR messed up my raid setup!

This is why I ALWAYS, I mean ALWAYS specify the exact model number on a procurement request for a part that could potentially have multiple variants. The new SMR drives have a different model number. But yeah WD was an utter scumbag for sneaking SMR into the Red series. Also the 1TB 2.5" Black has SMR, seriously, WTF? And to top it off, someone asked one of the manufacturers about a specific drive, at first they replied that they did not know and need to escalate (LOL, the amount of corporate BS), and then after they "escalated the issue" they had the gall to tell the guy that they will not disclose anything about the recording technology of a given drive model. I am not sure if this was WD or not, but whoever it was, they can shove an SMR drive where the sun doesnt shine. And I mean a 3,5" model.

Nah, often first line need to escalate, as marketing/corporate also lie to them. Sometimes a few of the first line are clever enough (read between the lines)/pay attention to specs, but often it's hidden to them too. I remember working for a massive company, bottom of the rung, and thinking one week "this product is really strange, why would we ever produce this thing, it's crazy" 12 months later turns out business was in deep trouble, and illegally hid their finances from the government and the crazy product was a quick cash grab to stop them going under!

You described me and my issues exactly here. I bought two WD Red drives last year because I thought they were the best and most reliable drives to use in a RAID1 to protect my most important data. I couldn't afford anything above two 2TB drives. My RAID array kept failing and re-building until the drives died and I lost tons of important data going back 20+ years! I was so mad because I thought i'd made all the right decisions. Thankfully, I was able to recover most of my lost data, but I had to pay a lot to do so. Until I found your videos here, I thought I was the only one dealing with this!

i'll go further and say potential class action lawsuit. because isn't that marketing deception? also bait and switch tactic? At least had they stated in their marketing and product page the switch from #efrx to #efax was from CMR to SMR, that would have at least been something. for laymens intended to using it for NAS, it would probably been better for them not to market these smr for "NAS" either imho. If lack of SMR in product page and marketing wasn't bad enough already, they didn't want to disclose this even upon further inquiry to customer support...... What reason is there for that if not trying to cover up their deception? The youtube video explained the situation very well. But i disagree with the premise that these oligopolies can self regulate. how did that work out for dram *rolls eyes www.forbes.com/sites/davealtavilla/2018/04/27/class-action-suit-alleges-samsung-micron-and-hynix-colluded-on-dram-supply-causing-price-inflation/#3603001717ce A slap on the wrist or a lecture isn't going to do much. You need to hit them with class action law suit and heavy fines, it's the only thing they understand..... isn't that why we have consumer protection laws in the first place? "A business fails to tell you relevant information regarding your product or service misleads you in any way." "The laws under MGL 93A prohibits activities that relate to overpricing to a consumer and use of "Bait and Switch" techniques. A court will award the plaintiff the damages if they can prove the (1) defendant knowingly and intentionally violated the MGL 93A agreement or (2) the defendant would not "grant relief in bad faith" knowing that the actions violated the MGL 93A agreement.[21] Additionally, failure to disclose refund/ return policy, warranties and critical information about the product/service are all in violation of the legislation, and can result in triple damages and lawyer fees." en.wikipedia.org/wiki/Consumer_protection#United_States en.wikipedia.org/wiki/Federal_Trade_Commission#Deception_practices For now i will be sticking to Seagate Ironwolf non pro 4-6tb. Because what other choice do we have with these oligopolies? Yes i know even Seagate did this smr bait and switch crap for some of their other drives, but at least they didn't do it for their ironwolf NAS drives (yet).

It really is about communication and trust. Many NAS customers might only have a fault tolerance of 1 drive in their setup, so knowing which particular model is a suitable replacement for a failed one is crucial. When WD first released some information about which drives had SMR technology they only indicated capacity, not SKUs. Not knowing the SKUs or which year they switched to SMR made it impossible for me to evaluate if I had SMR or CMR drives.

RAID 5 is bad for HDDs. When you use 4 drives @ 2TB each, you need to read 6 TB when a drives fail and you need to rebuild it. The change of getting a uncorrectable read error in a sector is about 30%. With RAID 6 you don't have this problem, the change that the same sector fails on 2 drives at the same time is very low.

In the WD case the issue goes beyond not labeling the drives as CMR or SMR. By labeling the SMR drives as Red NAS drives they are purposely marketing them for a use they are not suited for. Their response is even worse because it tries to gas light people into believing that the issue is people purchasing drives for purposes they weren't intended for while at the same time marketing them for just such purposes.

@@Stars-Mine Sure, but majority of NAS are sold with gigabit ethernet and 2 drive bays, maybe 4 bays if you get fancy. And those aren't performance critical and rebuilding RAID1 works fine on SMR. And isn't video editing write few and read many situation? Even the writes are sequential I think, usually you read from many source videos, apply effects etc and output compressed single video file? Still, the drives should be marked, but the issue isn't as bad. Professionals who need performance get SAS drives and/or SSDs if they need performant NAS devices. And one should never use (outside enterprise servers) hardware RAID controllers. Either use software RAID like Linux MD device (beware of the RAID write hole) or ZFS if possible.

consider here in italy. I pay on the distribution channel for an 4T ERFX drive about 110 Euros. This price is stable (excluding change fluctuations) for at least two years, so well before inception of smr tech on wd red line. Sum to this the general unavailabity of the drives. I own a small data center and last december i ordered a 12-bay NAS with 4TEFRX. I waited about 1 month to get the drive from a WD multinational (euro-level) primary distributor. I got the RED and not hte RED PRO because i don't need the speed (7200RPM vs. 5400RPM) because i intend to use that nas primarly for backup storage in the DC, and used the $$$ fo fill the nas bays (12 drives) instead of buying only 8. Moreover i really wished to expand my backup policies by buying more space, BUT the situaion here is that going up in the drive capacity DOES NOT SCALE ECONOMICALLY. if i need X euro per GB using 4TB drives, i more than proportionally need Y euro to buy more large drives, so contrarly to the normal wisdom that says tha the more you go up the more the cost per GB goes down, actually, if we think of the drives alone, the cost per GB on drives more than 4T acutally goes way up. I tried to factor in the actual drive bays used, energy savings, datacenter space to reach a comprehensive TCO per GB, but the TCO go UP with more capacity drives. So no, I am forced to remain on the slow EFRX drives because all other options for me have an higher price tag. To sum up: I cannot afford (and even if i could, i cannot justify) to pay more than double for double capacity. Actually for what i see the ratio capacity versus cost is about 2 in capacity to 2,7 in cost. No. WD, no, this is not good. ALL On the lower end red drives. Don't say anything about higher end drives where the factor go up more rapidly. that said, all other comments you did apply. and to not disclose the technology and basically saing in the posts something like is simply INSANE and a breach of TRUST with the vendor as you said very well in the video.

Thank you for bringing up the income disparity of the rest of the world. My 2TB HDD recently just crashed only after 3.5 years of usage, one that comes with my stock Dell XPS 8910. This has never happened before in my 20 years of usage of PCs, all of my previous HDD lasts way longer than 5 years, easily 7 to 10 years and possibly longer. All of the pictures of my newborn and my personal documents are all gone. It is only later I found out that the failed drive is a SMR drive and all of my previous drives are CMR. I'm from Malaysia, and you are completely spot on when you mentioned the importance of 2TB to 6TB drives. Over here, even 2TB may be a small luxury, so some of us even go for only 1TB option. Remember, Malaysia is not a low income country, it's considered one of the higher middle income countries and even then, not all of us can necessarily afford large capacity drives. Some can, but the masses can't. Had I know about SMR earlier, I would have just either opted for a more expensive CMR drive or reduce my capacity for an equivalent priced CMR.

A small but important difference is that those dramless SSDs are not marketed directly to a specific use case that their lack of DRAM makes them fail at. In contrast SMR drives marketed as NAS drives will fail in most (all except 'mirroring' or JBOD) NAS use cases. Dramless SSDs are annoying but don't shred user data, while a failed rebuild due to SMR drives will.

raid can be done with smr drives, it requires software or hardware updates, but, i have seen a few setups personally that actually dont write to the raid as the primary write, but to a high speed 10-15k rpm drives in raid, then, shifting the data to the storage raid, the software when rebuilding, has to be aware of SMR and that its going to have longer pauses and waits during rebuild. honestly, what i would like to see them do, is move to multi head stacks, i have tested drives in the past that used a single platter with its own heads, as the primary write platter, and another stack that starts to shift data to platters that are almost entirely written in SMR just having a small data section for rebuild/recovery use, the only down side was honestly that the test units we got to test were 5.25" drives. i suggested they do a different method if they use a 5.25 bay, use laptop/vrap size hardware, and just use a controller that can run the hardware with enough capacity and perf that, it may actually interest the market, as i pointed out, many geeks i know would be glad to buy a 5.25 bay drive if the perf+capacity are competitive, i also pointed out they could just use their own controller with 2.5" drives and a custom controller to combine them and manage buffer vs smr storage i suggested they look into using a setup thats in effect a mini-nas, you can mount in a system and connect with sata or sas. i also suggested something i know both server and home users would buy if done by a major company, that they use drives in a heavy SMR mode but, in a raid5 type setup, with an NVME ssd or 2 also being installed as massive cache, like i pointed out to somebody i know at WD, if their company made an external that used an M.2 (nvme or msata), or just sata ssd, as a cache on their external usb-c drives, they could sell drives that offer very very good perf, without a huge boost to cost, since they could use their own hardware just come up with a usb-c controller that can do that(their raid enclosures show they shouldnt have to work too hard to come up with, in effect, a hybrid drive, thats actually 2 in 2 enclosure.. as i pointed out, the main thing i have seen fail on SSHD/hybrid drives is the ssd cache totally taking a shit.. and..well... its also never a big enough cache to make the kind of difference most people would ask for... imho the smr thing, it should be easily identified not the games they keep playing, every company is doing this now... note: i still prefer HGST branded drives... goharddrive sell them refurb for excellent prices... 3-5 year warranty.. lowest fail rate of any company/brand every time i check fail rates for hdd's.. i know WD own them, but.. well.. lower fail rates are better...seagate really havent impressed me since they dropped to 1 year warranty and...i had to rma 3/4 of the drives i got from them during that time, ithin the first year, but the rest...within a few years...failed... wd, toshiba and hgst drives from the era... much lower fail rates... (i had 3 1tb drives of 4, that had head crashes within the first year of my own drives but, used seagate almost exclusivly back then and... well... customers/clients...all ended up quite unhappy with seagate... i got bitched out more then a few times by people upset it was taking so long for seagate to return replacements...then they get their full raid array replaced at once just to be sure, with a note on the RMA about needing matching drives, only to get back 4x1tb drives...from 4 different product lines... all refurb.. 2 that chucked bad sectors on a full format... 2 more rma's later they upgraded him to 2tb drives that did match, and had been pre-tested and formatted fully with zero smart errors... even after that.. within the year 1 had fully failed and one was failed by SMART due to havign too many bad sectors... anyway..yeah... not really a huge fan of having so few storage makers honestly... but... unless somebody comes out with a cheap high capacity, high reliability replacement for current HDD tech... we will be stuck with less then ideal solutions. imho, we are going to see more hybrid arrays, with ssd cache, feeding into large arrays of drives, often SMR drives im sure. i am told that people are working on linux os and software raid fixes that identify smr drives and handle them accordingly, understanding they will have times they have to pause and shift data to SMR sectors. what i think may be more ideal, is actually looking at the SSHD/Hybrid drive idea again, but, rather then 8gb cache, make 64-128g on top of a large 256-512m cache, for the mech section, making it so that a 64g cache drive actually has 128g of flash, wear leveled so that the ssd portion should never fail, with how cheap you can get small ssd's now, i have used a few on friends systems with primocache as L2 read/write cache for their raid arrays, used an old 240g with provision tweaked to leave 200g formatted capacity, on an array a friend has of 8x2tb wd black drives, that hes got in some form of raid with up to 2 drives failing at once, with no data loss, hes now got it mirrored to a mirrored raid of a couple shucked wd 8tb drives.

To me this issue is a simple one....their lack of disclosure denies me my right of choice and that could have detrimental consequences to my data. Imagine you are alergic to shelfish, walking into a restaurant that did not disclose that some of their key ingredients include shelfish.... We consumers are not foolish and would like to be given the opportunity to choose. If the pice of a 2TB SMR drive is say $70 and a CMR is say $85 I may very well choose to pay the extra for the CMR as I know what the consequences are in my specific use case which may be high random data write use. On the other hand if I just need a drive for say my weekly data backup I may choose SMR....but give me the choice!

Imagine you're allergic to shellfish, tell the restaurant and they STILL include shellfish. In such cases the staff have been convicted of attempted murder. If a customer specifies non-SMR to the supplier and the manufacturer submarines SMR into the chain, the product liabilities are horrendous

I would spend more for a CMR drive if I had the option. I don't like that they are being sneaky about it. I don't like the performance hit that SMR provides. I had got a couple SMR drives because they were not telling the difference in the spec and had to send them back because they significantly dropped the performance of my ZFS pool.

I thought your video was fantastic, you really touch on some great points regarding manufactures and users positions. What really knocked it out of the park though, was when you touched on availability and pricing models outside of the US. This makes it especially hard for consumers and retailers here in my country. We're wealthy and modern country by anyone's standards but as an export driven country our dollar is kept low against the US making imports expensive, especially in the current climate I expect things like electronics to really push up in price. Not only that but we have a high cost of living here which also pushes up the price a bit. At the time of writing the FOREX rate means 1 USD buys 1.65 NZD, not bad if you're an American buying NZ commodities! But if I go the other way it can sting. As a comparison at the time of writing a 4TB WD Red drive costs $154 USD whereas the same drive can be found in the US for $120 USD. This price difference will only increase as these prices will be based on previous pricing locked in before COVID, as economic forces shift that price will too based on the next price hedging negotiations.

Just received a new ST8000DM004 yesterday, and there's another problem. It's marked ""HDD sold as a component of OEM solution and not for resale. the product warranty does not cover HDD if removed from OEM solution." This despite still being in sealed packaging. The warranty then is with the reseller and not Seagate. This is a fishy arrangement. Fortunately the fact it uses SMR is not a problem for me, it will only ever be used for large file dumps and not as part of a RAID, so it's a good use match for this drive type.

The thing is that the manufacturers arent passing any of the the cost saving that come from using smr platters back to the consumers,so they managed to cut the cost of manufacturing down for themselves,but they're aren't lowering the drives price at all,in my country the smr drives are more expensive than the cmr ones,so we're paying more for an inferior product,what is this bullshit ? I personally think they should not put smr even in the blue drives,most consumers buy blues for their pc's without looking or thinking what they're buying,putting it in the blues would rely on the consumers ignorance to increase their margins by selling an inferior product that could cause problems down the line to people that down know better. I've studied this tech for a few days and i can say that the downsides of smr are to great to be used even on the average's user pcs,they are good for storing a lot of things that you dont plan of modifying or deleting or replacing for long periods of times and thats about it ,I've seen test of just copying a 15 gb movie to one of these drives and the performance would fall in the 10-20 mb's range if not less if you tried to push the drive even more,nas users are reporting 5-10 seconds of drive freezing and drooping from raid arrays when they tried to add a smr drive to their arrays,so far the more I look into smr,the more I realize that it cant be used for all that much.

This is a problem for at least some 5 years now, SMR drives all over the place and no one knows which ones use SMR or it takes some damn time digging to find out. Why not make it clear? No one wants SMR but HDD markers want easier way to make higher capacities so even 4TB drives may have SMR and you gotta select the correct model to not get one with SMR, or you order one model but get a single number different one which does have SMR because seller sucks at differentiating the specific differences down to the precise model code.

What's at issue is the principle of equivalence: a manufacturer can substitute something of EQUAL quality for an established product. What they can't do is substitute something that is "almost" the same, or which will break badly when the product is used in ways the old device was fine with. A drive that works fine for 10 minutes of writes then turns to custard fails that test miserably and if the drivemakers are giving any trouble of kickback on this then the first port of call for most people culd be small claims filings - the reason being that it's cheap and quick to file, hearings are quick and you WILL get all your filing fees back when you win and lawyers are banned from small claims courts.

The biggest problem is that there's absolutely no logic to their lineup, if you want a 4TB cmr drive you should go for a wd blue and not a red ? I don't expect anyone (at least consumer) to look up at specs sheets when buying hard drive (and they wouldn't even find their answer there), so why are they destroying their RAID designated lineup by mixing tech into it ? They destroyed all of their arguments in favor of "choosing the right disk for the right use" themselves, so all in all, keep shucking since you take as much risk going this route than trusting their marketing

You seem to be ignoring the fact that people use lower capacity drives to reduce rebuild time and as such reduce the risk of failure. So it's not just about their price. Also not everyone needs that much storage. So it's not about having the opertunity or the means, it's about picking the right drive for your setup. E.g. I know people who bought we red as opposed to the pro because they wanted the lower spindle speed.

Western Digital as a brand is now dead to me for the foreseeable future. I have exclusively purchased and recommended WD drives since the mid 2000s when the rash of dying seagate drives made WD the obvious choice for reliability. In the past year I have set up three NAS at home and work all using WD Reds, and while I have based on their current disclosures dodged this bullet, I just don't trust them anymore. Who knows, in the coming months we may learn that 'SOME' 8TB and 10TB models are also affected, or that this also impacts a 'small number' of black or gold drives. They have lied by omission and sold a product which is totally unsuitable to normal NAS usage as a NAS product, putting their customers at risk of data loss during failed rebuilds. At this point all we can do is spread the word and leave appropriate product reviews to warn the unaware until WD stops selling dangerously misleading products.

Thanks for your insights. I'd like to ask, is this really as big of a deal for RAID systems as people make it out to be? I come from a perspective of "never trust the disks". This is why backups and HA (if you can afford it) are so important. There seems to be a case that the disks are perhaps slower to resilver or restore a RAID to a healthy (undegraded) state. But how big of a deal is this? I must be honest, I never knew that CMR/SMR technologies were a thing before this scandal so I place less emphasis on it than many others. While my perspective of the OEMs is altered due to these events, I'm not necessarily willing to write any of them off or boycott them (yet). I'm curious if someone can boil down to a non-storage-expert why I should worry about this and whether it's worth the time increased expense to worry about it. Why upgrade to CMR disks when I could instead buy more SMR disks for larger redundancy or backup arrays?

Yes. It is a big deal. An SMR drive can take days longer to rebuild, and has a higher risk of failing the rebuild altogether. Now, if you take these drives on purpose, that's great. If you're just looking to continue arrays that have worked before, unknowingly using an SMR drive can really mess things up.

Yes, you could jump onto some class action suit but it will drag on forever and at the end of the day you're likely to get $10 out of it, instead of a replacement drive or full refund - and let's face it, what most of us want is either a working replacement or a refund so we can go purchase a working replacement. People should ALSO bear in mind that for companies like WD/SG/Toshiba, they would _prefer_ to face class action lawsuits than thousands or millions of small claims actions - it's known as the death of a million papercuts when that kind of thing happens and can cost a company hundreds of times more than dealing with class action suits. What that means is that once the small claims filings start rolling in they're more likely to adopt conciliatory tones to placate customers

SMR should only be used as a bridging technology between SSD and magnetic tape in datacenters. SMR is not suitable for consumers. With this scandal I predict that consumer devices will finally shift away from HDDs completely. The pulling forces from the NVMe SSDs in PS5 and XBOX SX and the coming shift to 12VO PSUs will make it hard to justify SATA HDDs (especially SMR HDDs) in the consumer space. If you need more storage as a consumer there will still be some CMR HDDs available for use in NAS and similar use cases for a while yet.

Not long ago I went to the store to buy a few drives for my NAS. Configured in a LVM manner (similar to RAID) After some "weird performance issues" I went back to the store asking them about it. They decided to test the drives. They concluded them as "defect". The new ones I got back had the same "fault". Now the store started to wonder what the eff is going on, so they went ahead and picked out a larger batch of drives to test. Guess what... They all had the same "fault" Poor performance in some specific scenarios. I cancelled the order and got my money back, and the store started to have a conversation with the manufacturer about a "faulty batch of drives". A few weeks later... Store return to me telling me that the drives I returned had no flaws nor did the rest of their batch. They where simply SMR drives. "Hey... didn't I explicitly ask for non-SMR drives when I asked back then?" I asked. The store acknowledges that they recall that request. Even they didn't know the drives where SMR until the manufacturer told them. There were nor marking on the label indicating this, nor was there any such mentions on the manufacturer's website. After some time I came to the conclusion that one will have a really hard time getting CMR or any non-SMR drives nowadays. Even the low capacity 2TB drives are likely to be SMR nowadays. Knowing this I can adapt the LVM configuration and tune the file system to take this into account to remedy some of the performance loss. I accept that this is the future for "spinning rust" drives. If only manufacturers were willing to mark/label their drives accordingly it would've been a lot easier for everyone involved. Not marking drives SMR when they are?... such a scumbag move!

This is a major trust breaker in WD for me. Hearing the others also switched silently without any spec sheet indication and clear labeling on some consumer/SMB drives is worrying, but WD doing it on their RED and BLACK series (although black only for one 2.5" capacity) will make me take my money elsewhere the next time i'm buying HDD storage. They broke their own sub-brands/series, and you can't trust their consumer/SMB labeling anymore. For specifically non-essential archival storage or a drive to dump data to for mid-long term and delete/overwrite contents bulked SMR may be overall beneficial if the cost delta is big enough. Though I've been moving more to keeping online backups of anything essential and SSDs for any frequently accessed data. My local HDD bulk storage is mostly for convenience at this point, but also serves as another logical/physical instance for backups. I wouldn't trust a single physical or logical instance of storage with anything i couldn't afford to lose.

I'm still having difficulty wrapping my head around this, the only downside I've really learned from this video with regards to SMR is the lower end random read and write performance. I can gather from the conclusion and the comments that SMR is dangerous for certain types of RAID arrays and arrays that currently contain CMR drives, but exactly how they are hasn't really been explained all that well to me in the video. This is concerning because I plan to setup a NAS in my own home for data storage in the future. I'd appreciate it if anyone could explain these dangers to more elaborately.
@railotaku

My understanding is that many NAS systems are of the view that slow drive response times can indicate a potential drive failure. During a rebuild following a drive failure the NAS spams the remaining drives with random read and writes as it rebuilds the data. This quickly fills the SMR drive buffer as the drive has to re-lay out all the tracks in the block where data was changed, so the drive's response times increase to 20 to 30 seconds*, all the extra writes/reads mean the drive will also get very hot too and may overheat if high temperatures are sustained**. If this happens too many times the drive is liable to be marked as failed as well. Depending on your redundancy that could mean data loss if the previous rebuild was not complete if the SMR gets booted. Should also add that mixing CMR and SMR is a bad idea because many NAS systems will assume the one drive that's always holding things up is a possible failure. Now in theory the NAS manufacturers could update their firmware/software to account for SMR drives and their 'issues', but the drive manufactures don't just hide it on the label, often the drive will try and hide it from the computer as well, some drives may tell you they support TRIM (just like SSDs), that usually indicates SMR, but others do not. The manufacturers will not publish a list of which models are SMR, so far much of the work as to IDing what a particular model uses has been through people like smartmontools poking at the SMART data and drive performance for opensource tools *Copying 100GB of small files onto an SMR external the other day took over 8 hours! At points the drive was down to 60 bytes/s **With SMR in the mix I'm aware of rebuilds taking over a week, so an overheat is very possible.

Thanks for the content really interesting.. 100% agree disclosure is key for Trust. Manufacturers should tell us and give us options.. so i can choose to pay a couple of euros more to replace a 2TB disk in my nas. i can't afford to replace all disks to 10TB but i have one disk that failed so now i'm looking to replace 2 disks and i'm going for the more expensive CMR..
