[@alexisrivera200xable]

I have been a computer technician since the late 90's. This channel is one of the ways I keep myself learning new stuff and refreshing my understanding of the stuff I already know. It's relaxing and more importantly for me clear to understand. Your voice, pacing and delivery style is top notch so I do not need to crank up the volume as high as with other channels.

I started in Freshman year in high school in 1975 programming an unseen computer in our computer lab with cards and pencil marks. Between terms in tech school I got the opportunity to take a COBOL class, programming an IBM 360 with punch cards. I still have my old TRS80 computer! Today I service automated HVAC controls and computers. You, sir, help to keep me up-to-date on the technology of computers and for that I am eternally grateful. Keep up the great work! You are of great value to people like me who sometimes struggle to keep up.

[@peterslater2914]

I can relate to your comments on punch cards, and Mark sense and the TRS computer. I had an equivalent to the TRS which was Australia's answer to the TRS which was the Dick Smith TRS 80. My son learnt programming on this computer at the age of six. His first program was the game meteorite. This brings back fond memories of 4k memory utilisation a tape drive to store programs alot of peeks and pokes. My son went onto work on movies like avatar, tin tin, planet of the apes, James Bond, just to name a few. From humble beginnings to using 300 computers to perform rendering of huge images. Thank you for the memories. The computer had a bit of disastrous end. I came home from work and I went to see my son who had dismantled the computer and had the parts all over his bedroom. I said to him well you now understand how to dismantle a computer and is valuable knowledge. That computer never worked again. He went onto design computer farms to render images.

[@rdhunkins]

Christopher, I just want to say that I've built my own computers since the 90's. But I only do it once every 5-10 years or so. Back then I bought books, especially "Build your own 386 PC and save a bundle." Each time I went to build a new PC, it got paradoxically harder. The internet had the information, but it was scattered and took a while. Your channel helps a lot for a guy like me who can't spend a lot of time keeping up on the technology. Thanks!

[@VulpisFoxfire]

Yeah..actually building your own PC is pretty easy, it's selecting the right parts for it that has gotten harder, between the CPU socket options, RAM types, etc..

[@BlackEpyon]

I've been doing it just as long, but I was a kid when I started in the mid-90's. The terms have changed, and the architecture has gotten more complex, but the fundamentals haven't.

@@ExplainingComputers I used to one the support and development of a transaction processing operating system back in the 1970s which could have over 1,000 online users and had 768 kB of ferrite-store main memory at around 10-12 transactions per second. Something called an ICL System 4, which was a licensed copy of an RCA Spectre which was the first attempted IBM 360 clone (and basically bankrupted RCA). It was a 24 x 7 system with disk mirroring and full, dual transactional logging. It, and a second machine of the same specification provided all the central air cargo handling system for the UK as well as automated customs clearances. It used 3,600 RPM 14 inch 30MB disk packs called EDS 30s. Massive things that the size of curling stones. That system got ported onto IBM mainframes and the same core systems ran until near the end of the century. For some other applications (notably RAF stores management) the operating system ran for another 10+ years beyond that. At the end of my career I was working with machines with 256GB of main memory, 128 CPU cores and disk storage arrays in the petabyte range. So, coming from the days when every bit counted, we are now in an era of profligacy, or so it seems.

My desktop computer has both SSD and a HDD. The main programs and the boot system are in the SSD and the rest of my files are in the other drive. The difference is huge in terms of speed. Thanks for another video. Cheers!

[@Sup_D]

I have been using HDD for 7+ years now and still on Windows 7, and was thinking of maybe buying a 2.5 SSD for boot-drive and install Windows 10 on it. But then i noticed that both my i7-4770 and Intel DH87RL Motherboard don't have any driver support for Windows 10, and since both the products have been discontinued and there is no new drivers for them, not sure what to do. And with Windows 7 not having official support anymore, i am a bit apprehensive to do a fresh install of it again, even if i have a original copy of Windows 7.

[@AnthonyElsom]

@@Sup_D I tried winx for a week and discovered it's slower on my rather old but trusty Dell laptop. Stick to win7 for games, but go linux for everything else. After some distro hopping I settled for Linux Mint Cinnamon with KDE Plasma desktop on top. Whatever you decide on though, upgrading to SSD will speed up your system drastically..

[@FlyboyHelosim]

@@Sup_D I still use Windows 7 as my daily driver on two laptops. No need to move to Windows 10. If you're happy with Win7 and you've got things running smoothly, stick with it as long as possible. So there's no official updates anymore, that's just one less headache. Install anti-virus and anti-malware programs, run them once a week, and use common sense online.

That part about the interfaces types are well explained 👍 End user need to pay attention especially on those m.2 types I work with one of the storage manufacturer, and the reason why theres so many interfaces (even those SAS and U.2) is because to give options for consumers/data-centers to migrate to ssd while still use their existing HBAs thats probably still under warranty (not all datacenters have the budget of amazon/fb)👌

[@ffighter8420]

Your ssd lessons has helped a lot, especially the previous ssd lesson on formatting ssd drives. That lesson came in at the right time. Found out the hard way that ssd drives when purchased are unformatted and don't show up when connected to your laptop, even with magician software already pre installed. Poor documentation from Samsung forced me to return it believing it was faulty. After seeing that video of yours is when I learned about how to format it. Thank-you. A grateful Manitoba Canadian.

[@darnell8897]

I generally dislike when companies break from standard for their own nomenclature, but I agree with Samsung on this one. It's clear that bits per cell will be growing for a while so, rather than forcing customers translate [M,T,Q,P] -to> [2,3,4,5], using "Multi" generically makes more since. In fact I'd argue that we should get rid of the "M" altogether and just straight to 1LC, 2LC, 3LC, .. [n]LC

[@userjames2009]

Although the LC part *also* doesn't make sense because a 2LC flash has 4 voltage levels, not 2. And a 3LC has 8 voltage levels, not 3. They should be called 1-bit cell, 2-bit cell, etc. 1BC, 2BC, 3BC, ...

[@jpdj2715]

Interesting overview. To add to that a bit of experience from a Windows sufferer. Biggest threat to SSD lifetime that causes lots of P/E cycles are Windows' dependency on its page file, and many apps that rely on temporary files to register some state information as surrogate global variables. Biggest threat in Windows to stability is "fast reboot" that is on the critical path of sound updates. So I switched that off and now my page file needs to be created every day. I have tried to run Windows without page file and theoretically this should be possible - in practice you can only run Windows, use its control panels, and run simple apps like Notepad. Biggest threat to I/O performance, including NVMe, is the South Bridge chip on the motherboard where most I/O devices are in competition for CPU to access them. To defeat some or all of these problems, I bought a PCIe add-in card that facilitates a Windows RAID 0 and gives direct access from the CPU's I/O lane to the card. With 4 lower capacity SSD that have a relatively large cache, I now get higher I/O speeds on that, than I could ever get from an NVMe on the South Bridge. And note here that even the NVMe connectors on the motherboard listed as PCIe are generally on the South Bridge. Now I keep my I/Os distributed across separate I/O lanes and the cheaper SSD RAID 0 array does not contain data I need to backup, ever. Or it is backed up by the application after each session like the Lightroom catalogues. I have seen the P/E cycles (TBW) and in product name terms Samsung EVO would have been good enough, but I still bought into the PRO version. Here I run RAID 1 with 3 arrays to keep e.g. OS and user data separate. Really important data is stored in my NAS on RAID 5 which replicates all updates to a second NAS which replicates to an offsite NAS.

And, since the MB only has SATA2, which can't get my SSD anywhere near to it's rated speed, I am now ordering a VERY similar used MB with SATA3, USB3 and digital audio out. All things I want and for a good bit less than a PCIE - M.2 adapter and M.2 drive. Not as fast, but fast enough!

Thank you very much kind sir!

[@NormanBaatz]

So much information in 14 minutes! I was surprised how much I learned about a topic I thought I was more than just vaguely familiar with.

[@N0Xa880iUL]

The write-rewrite cycles sound concerning....Won't gamers degrade their ssd's faster? I dont know much but id like to know more.

[@xrafter]

Of course. Gamers will kill there ssd drives faster than a normal person. Because some gamers downlaod ton of games every day and then format it and download it again.

[@ExplainingComputers]

I have a video here on SSD life expectancy! kzbin.info/www/bejne/Y4m9f6Vtorhjn9k

[@N0Xa880iUL]

@@ExplainingComputers Thanks! Going straight to it!!

[@jhonbus]

It does sound worrying to begin with, but when you think about it, even if you have to replace your SSD after 5 years, it's not that bad. Even replacing my fancy expensive drives, imagine how much better and cheaper the replacement will be in five years. I'll probably want more than just a new drive by then, anyway.

[@N0Xa880iUL]

@@ExplainingComputers That video definitely calmed me down. No panic! Edit: Still don't understand over provisioning though.

[@Unteroffizier]

Truly appreciate such videos and this channel. It cleared the confusion with all the modern hard disks configurations and standards!

QLC "Waterfall" was in the charts 25 years ago. Oh wait, that was TLC.

How have I never known this channel existed, this is the greatest thing I’ve ever seen

[@ExplainingComputers]

Thanks. :)

You didn’t even mention 5 1/4 inch hard drives. They were used for years.

[@VulpisFoxfire]

I remember the 60MB 5.25 "brick" HDD I hade as the first one on my old Amiga. Much like floppies, I commonly download files larger than the entire capacity of that storage now...

[@OldDogNewTrick]

Back in the mainframe days we had big disk drives the size of a washing machine, and the storage medium was a disk module with a set of about 5 or more 14 inch platters with an iron oxide coating for the data storage. A big one like this held an amazing 300 megabytes of data. When the computer was busy doing a lot of data transfer, the read/write heads would dance back and forth with enough momentum to even shake the disk drive. flic.kr/p/7zuKiQ

[@pixelmite]

Awesome video! This explained SSD's in a way that I can understand better than most.

As a hipster, I store my data on vinyl records.

[@ExplainingComputers]

Groovy! :)

[@VulpisFoxfire]

@@ExplainingComputers ..(*sound of 2 drums and a cymbal falling off of a cliff..*) There are a lot of interesting alternatives for data storage, but be aware of the drawbacks, too...like the clay tablets someone mentioned above, data density is rather poor, plus you have the needle-wear degradation problems when you use them often. :-) (As far as oddball techs go, I've always been fond of the internet via messenger pigeon protocol...I wonder if anyone's ever worked on the speed and reliability issues with that? :-) )

[@d.barnette2687]

Well...maybe... until someone jumps on the floor or bumps your storage device and the needle jumps a groove leaving a scratch behind. Good luck getting that needle to track correctly from now on. :)

[@Vaxtin]

Lots of 4+ year old videos out there, though they may be good information it's always nice to get up to date explanations for these things.

[@JovakiinJenkins]

thanks man this is the video that cleared all my confusions about ssds!

[@ltlk937]

Fantastic video as always. No kidding, No one explains it better than you.

[@NicoDsSBCs]

Hi Christopher. I again learned a lot. Didn't know the names of them were because of the size. Also not the precise way it worked. Thank you. I use NVMe as RAM replacement with swap files on my RK3399. So I do write a lot to it. But I accept that I need to replace it about every year. Just bought a new 512GB NVMe to replace my 256GB one I've got now. Also bought a PCIe to NVMe adapter for my aging pc. So that's where my old NVMe drive will go to. I've also got a USB3->NVMe adapter. Very useful to test USB3 performance on SBCs. I use it to boot Linux on my PC. More than fast enough for that. I had the pleasure of working on a 32-core ARM server. All cores at 3.3Ghz. Amazing to see such performance out of an ARM CPU. I made a video about it, and wrote a review. The link to the written review is in the video description. Have a great evening. Greetings.

[@ExplainingComputers]

That 32 core ARM server is a very interesting piece of hardware -- for others, Nico's video is here: kzbin.info/www/bejne/bXPXpnmnn56Mm7M
