SSD Life Expectancy

  • Published on Mar 26, 2017
  • SSDs have limited program/erase or P/E cycles. In this video I discuss the life expectancy of SLC, eMLC, MLC and TLC drives, as well as covering wear levelling, over provisioning, and TBW, PWB and DWPD endurance ratings.
    Note that the data presented in this video was obtained from a great many sources, including all major SSD manufacturers, and was up-to-date as of 25 March 2017. Note also that the second SSD listed in the table of client SSDs at c.6:41 is a Samsung 850 Pro, not a Sandisk 850 Pro (which does not exist). Sorry! :)

    I'm still sticking to a traditional HDD. In my own experience, HDDs last a very very very long time. I have had 1 fail EVER. I still have old 20G drives that work fine, they aren't being used simply due to being too small. I have a 500G drive in my system that, while doesn't see as much use, it still works and is probably 14+ years old now with no sign of stopping. So, I don't see HDDs as guaranteed to fail, but SSDs, while faster, are guaranteed to fail, which bothers me a great deal as I don't tend to upgrade as often as most, I certainly want one to last longer than 4 years or more.
    I may grab one for my operating system drive, and use a HDD for everything else. I can also get a 4TB HDD for the same price as a 500G SSD, 8 times the storage capacity with less of a chance to fail is well worth the wait for loading times.

  • JuanMamaril

    For me my main concern regarding the P\E cycle counts on SSDs is the fact that an OS, like Windows, for example, regularly writes to and deletes data, whether be it system log files or even system restore points. Not to mention games and most third party apps also still save important files like save game files on your system's root directory, further reducing P\E counts, my faith on SSDs will not be fully realized, unless either SSDs can overcome their current limitations or OSes can make it so they don't constantly write and\or delete stuff, as well as other apps no longer writing to your root directory, I may not put my faith on SSDs. SSDs may be faster then mechanical drives, but at least HDDs last longer when a user takes real good care of his\her system.
    Fun fact: I have two Seagate 250GB Barracuda HDDs and they still haven't failed on me even after nine years. And to think Seagate isn't exactly reliable these days.

    • James Conner
      James Conner 21 day ago +1

      +JuanMamarilI do see what you are saying, I get it. However, it is not that difficult to save to a drive other than your main drive. Windows 10 makes it really easy ( It is just a few steps, and the first time I did it, I just googled it and watched a video. Additionally, yes the OS writes to the root drive a lot, however "A typical TBW figure for a 250 GB SSD lies between 60 and 150 terabytes written. That means, to get over a guaranteed TBW of 70, a user would have to write 190(!) GB daily over a period of one year. (In other words, to fill two-thirds of the SSD with new data every day). In a consumer environment, this is highly unlikely." I am not sure how you are using your PC, but I don't think Window is writing 190GB a day. Even it if writes 10GB a day, it should still last around 20 years. With wear-leveling, and other built-in features, the life of SSDs is fairly long. Now, will they ever be as long as a HDD, not likely. Not trying to be argumentative or anything, just trying to see if I can inform you on the fixes they have made to SSDs that you have concerns about.

    • JuanMamaril
      JuanMamaril 21 day ago +1

      +James Conner doesn't solve the fact that your OS still writes regularly onto your boot drive frequently with and without your consent. Also say you do install third party apps like games off of your SSD, they still save\write inportant data, like game save files and game setting files onto your root directory which is your SSD. Sure you could setup your OS to place user folders off of your Root directory, IF you know how. But the average home user who isn't tech savvy usually don't know how. So again as I said, unless OSes are better developed to utilize as SSD, by not writing too frequently onto it, or SSDs overcome that P\E cycle count limitations to extend their life I will NEVER put my trust on an SSD faster load times be damned. Unless MAYBE if SLC SSDs become cheap enough to be accessible to home users I'll reconsider. And who told you better cooling can extend the life of an SSD anyway? As the video said, it's all about P\E cycles.

    • James Conner
      James Conner 21 day ago +1

      I have an SSD setup as my main OS drive. You can select another drive to be your main storage, which will help extend the life of your SSD. Also make sure you have adequate cooling on the SSD, as heat dramatically effects the life of the chips. I guess the short answer would be, use a different drive for storage, and keep the SSD at a decent temp.

      You've not been scammed. Both of these drives use consumer tech, and both will probably write roughly the same volume of data in their lifetimes. But for industrial drives in very heavy use (eg in servers that a reconstantly writing data), write speed will make a difference.

    Someone said the disk inside a standard hd can shatter? Have you taken one apart? I have, they are a very strong steel, not likely to shatter. In 21 yrs of home pc's I have only had 1 standard hd fail, in the last year I have had problems with 2 ssd drives, they may be faster, but in my home they are not more reliable. When my current ssd's fail I will probably try a hybrid.

    He is correct when he says to save your data on a 2nd drive. I do exactly that and I never have the 2nd drive constantly connected when working on my PC. It only connects when I am needing data from it or storing more data to it, then it gets shut down and disconnected. This extends the life of the drive, whether it be a hard drive or SSD.

    • ExplainingComputers

      Regular PC RAM uses power to hold data; SSDs have to hold it electrostatically when the power is off, and it is the technology (memory cells) for that which wear out. In comparison, standard PC RAM just turns transistors on and off to store data, and these transistors will survive billions upon billions of switch cycles.

    SSD's are game changers, My first SSD was a 256gb Samsung 840 that I bought in February 2013, just before the buggy 840 EVO came to market. It was my daily use boot drive until roughly a year ago when I moved to an nvme drive, I still use the 840 as a secondary drive and it's never put a foot wrong. According to Samsung Magician it's written a total of 24.9 TB's & it states the drives condition is good, The performance test show sequentials of 559 & 258, What's not to like about that? The 840 experience is why I prefer to stick with Samsung drives nowadays. Since I bought my first SSD I've also bought 5 other SSD's & 5 mechanical hard drives, The SSD's have all been faultless but two of mechanicals (a 2tb & 3 tb) have failed so now that SSD prices are finally dropping enough to put larger models within in my budget I'm gradually making the move from mechanical to solid state.

    What about comparing modern SSD with old classic hard drives that if you remember although its low memory capacity the life expectancy was that good that even when being over 10 years old and sounding like a metal disc grinding inside, it still worked and still run and still could be 100% used. Compare with that, NONE of today's modern Hard Disks can be better then that as all of them break much easier. So my ADVICE is keep some really old Hard Drives for your most sensitive information, do not throw them away as they are very hard to find on the market, but their life expectancy is great even though they are usually kind for small at around 10GB and even smaller. But if you have really important data and those Hard Drives are not far too used up, then you are much more safe for a long time.

    It’s common knowledge that mechanical drives outlive SSD at the present time and maybe into the foreseeable future time has proven this. My concern is (unless you’re a gamer) what possible advantages are you gaining using your computer in a family or office environment? Ok your computer may start fast (Windows 10 has always started fast) it’s certainly not going to make you type faster, play your music or films faster ( bit of sarcasm) so what are you gaining? I use my computers for video rendering but I do so much I doubt an SSD would be an advantage as the next video would still need to be filmed! so all I’m gaining is time! Until a replacement can be made with a lifespan of at least identical to that of some mechanical drives I think I’ll give the rush to SSD a miss. Very informative video btw.

    When I first heard about ssd's 11 years ago they were super expensive and small. Today you can buy a 480gb ssd for just $60 which beats me why imac don't include them. Needless to say, put one of these on a macbook pro or the like and bootup speeds are rediculously fast. Makes an old computer compete with a new one with the spinning disks.

    This is what I call elaborate and informative. Thank you for that.
    I'd just like to add from a companies' perspective, that SSDs do hold their risks, if you have a ton of throughput in your environment and I'm not talking about PCs and consumer hardware.
    We got like a couple of hundred TB of storage and a few hundred GB movement each day 5-7 days a week, so disregarding the cost factor difference (which is tremendous, btw), we rely heavily on writing and having drives needing replacement because you can't write anymore.
    on top of that: if an SSD dies, it just dies.. you don't have much warnings around it, which can be a showstopper.
    redundant, safe and distributed network file systems are the way to go for data centers, unless you got a really really good reason to use SSDs, take my advice: dont just put them everywhere. :D
    you can always split your storage pool smartly into SSDs and HDDs and even use SSDs for caching on some systems.

    Also as far life expectancy of mediums I would like to see an episode on tape cartridges such as LTO Ultrium 5 Data Cartridge and or LTO Ultrium 6 Data Cartridge. I realize that these tape drives as expensive as most computers but it would still be interesting, and I not heard much about tape drives since MS-DOS or the Amiga era..
    I would also like to find out more about "SAS" AKA Serial Attached SCSI controllers, and the the Idea that one Mini SAS cable can control 4 drives and that 4 Mini SAS ports on one 8x PCI Express controller could control 16 drives. Which would be perfect for a central file server.
    Also the difference of SAS drives and controllers compared to SATA 3 controllers and drives. - not just one is enterprise and one is consumer. Some RAID breakdowns as well especially including Raid levels compared to each other by their usefulness based the three factors, speed, mass storage and protection. Raid beyond RIAD 5 are still a mystery to me.
    The difference between Fiber Optic networks vs standard Ethernet networks as well actual speed difference the 10gb (gigabit) difference in speed. Could a standard 720 rpm drive really transfer 1.250 (1.25 Gigabytes), or would a SSD need to be used for transferring that much data at that speed. Also what is the SFP module device and why it is needed. I sound like the only guy in class raising his arm saying "me, me, pick me teacher".

    Actually what you didn't mention is how secure is the data over time. For example say you use SSD as offline storage. You don't reach the maximum PE cycling, you just load it full and put it in a box. Ultimately you're literally storing a ridiculously small charge in a tiny cell. You come back after 10 years. Is that charge still there or has it leaked away? Do you still get your data back or has it turned to mush? How long can one expect to store data on a drive like this? 10 years? 20? 30? 100? (Last couple probably facetious as its unlikely anything will be around to read the media in 30+ years.)

      SSDs, with minimal P/E cycles, should maintain data for a few years (ie 2-3). Like a HDD, an SSD needs refeshing (via read, not write) to reliably maintain data over an extended period of 5 years plus.

    aaaand back to HDD's I go. Seriously, I have an SSD and so much ends up on the mechanical drive anyway it's almost pointless. When 4TB SSDs with high P/E cycles can be had for $100, then I'll be on board. Until then, I'll wait another 30 seconds for Windows to load after a reboot.

    ExplainingComputers : Thank You Sir ! Your presentation regarding SSD (Solid State Drive) on their limited program/erase (P/E) cycles , the discussion on the life expectancy of SLC, eMLC , MLC , and TLC drives ! Plus you also cover ~ wear levelling , over provision , TBW (Terabytes written) , PWB (Petabytes written - Petabyte = 1,024 Terabytes ) , DWPD = drive writes per day (number of full SSD P/E every 24 hours) and most modern SSD's are able to withstand 100 Terabytes written or more , thereby lasting as long as the other parts for many years in an end-user PC ! *Yes , I now have learned how an SSD functions with the different terminology explained clearly ! Thanks Scarboro

    The proper way to utilise a SSD, is to properly setup your OS and it will last longer than you: The trick is to do a frugal installation, (Windows to go) so basically the SSD is only read once at boot for a boot image like after hibernation, and very fast sequential read to a ram disk. At shut down, the opposite happens where the ram disk is written once to the SSD at shut down. You need a ton of RAM though, which actually is cheaper than SSD, but you have even higher speeds than running of the SSD directly and it doesn't wear and can be used by your grand children to play old school games 50 years from now.

    Not covered: Data recovery. Whereas a failed HDD's spinning platter can be extracted and placed into a temporary housing for (at least some/most) data retrieval, once an SSD fails, all bets are off. So it makes more sense now than ever to have your data stored redundantly.

    • ExplainingComputers
      ExplainingComputers  2 months ago +2

      All true, but data recovery is not a life expectancy issue! :) So it was not discussed in this video. All drives -- HDDs and SSDs fail -- and so no data storage strategy should ever count on recovering any data from a failed drive. Backups as you note are always vital -- ideally 3-2-1 rule -- as I have covered in other videos. :)

    How does it affect the life expectancy, if you have most of your work on Read Only.

    • ExplainingComputers
      ExplainingComputers  2 months ago

      SSDs can only erase blocks, not cells. As you say, server use should could well be minimal write (depending on its usage and how much RAM it has to avoid caching). I would not worry about read loads on an SSD! :)

    • Jonathan T.
      Jonathan T. 2 months ago +1

      +ExplainingComputers Thanks for replying. Yes, but in a server, that would probably be insignificant as most of my process is Read & Update.
      Flash has got Write & Read & Erase right?
      If I'm touching a cell, that already has got data, in that block, how much P/E movement would there be in that block. Does it simply just write over the existing cell block or they need to erase?

      Now I'm worried about using QLC for heavy read work hahaha.

    • ExplainingComputers
      ExplainingComputers  2 months ago

      The less you write, the longer an SSD will last. Note that using Windows and also a browser creates constant writes though, as both create cache files.

    Thanks again, Chris. As always, your explanations are crystal-clear. FYI: we've been migrating our operating systems to a RAID-0 array of 2x and 4x quality 2.5" SSDs e.g. Samsung models. There has been a healthy debate whether 4 @ 120GB in RAID-0 have the same endurance as a single 480GB JBOD SSD. We use a combination of both, but OS performance is noticeably better when hosted by a RAID-0 array with 4 member drives. We also have a robust backup policy which stores drive image copies of our OS partition on all other data partitions in any given PC. Because storage capacity is relatively cheap now, we simply "age" our drive images by appending a serial number "suffix" (or filename extent) e.g. images.001, images.002, images.003 etc. Once any given OS stabilizes in one of our PCs, we use Partition Wizard, Symantec Ghost, or Acronis to "Migrate OS" to the primary partitions on all other drives installed in any given chassis. This policy allows us to change the BIOS boot drive easily, which then allows us to restore a good drive image by running the restore task rapidly from a backup OS. As such, every physical drive in any given PC chassis has 2 NTFS partitions: a primary partition for a working OS, and the rest is formatted as a data partition. The other great advantage to this functional policy is that it's very easy to recover from a virus or malware infection: we simply boot from a backup partition and restore a recent drive image of a working OS. Lastly, we also recommend that your viewers investigate the advantages of ramdisks for storing frequently used files, like the Firefox browser cache. Because modern RAM typically comes with a lifetime warranty, the "write endurance" of such RAM is effectively unlimited. In fact, our experience shows that our RAM sticks become obsolete long before they fail! Corsair sent us a check because one of their DDR2 sticks finally failed, but Corsiar no longer manufactures that model. Corsair did honor their lifetime warranty by reimbursing us in full for the original purchase price. Fortunately, G.SKILL still sell a compatible replacement. And, the performance of most browsers is significantly faster when their browser caches are moved to a ramdisk. Hope this helps. From the college of hard knocks, Paul out ...

      Here is how the drives in our "Wintel" PCs look, physically and logically:
      A: = floppy disk
      B: = (not used)
      D: = optical drive (typically)
      Physical Drive 0 (zero):
      C: = primary OS (usually a RAID-0 array)
      E: = data partition
      Physical Drive 1:
      F: = back copy of C:
      G: = data partition
      Physical Drive 2:
      H: = backup copy of C:
      I: = data partition
      and so on ....
      R: = for browser cache(s)

      About 5% of SSDs fail in the first 3 years, regardless of make. Kingston have the best customer service:
      The Kingston A400 are good SSDs and go up to 960Gb.
      A 120Gb SSD with TLC NAND, like the A400, can easily write 2Gb daily for 50 years. If they still work after 3 years then there's a good chance they could last for decades. Make sure you have much more memory than you use.
      You can get free software that gives you lots of info on your SATA SSD/hard drive
      A bigger hard drive is more reliable since you can just copy your files to save wear and tear. An operating system can be re-installed in another partition. Doing this means you could get 6-7 years out of it.
      SSDs use much less energy than desktop hard drives. In 2 year's time SSD prices will have dropped a lot. By then it won't be worth running a desktop hard drive.

    I program from home on an SSD notebook and save all my work files each work day. I backup to two cascaded network hard drives AND a flash drive (takes about 5 mins to complete the backup - plenty of time to take a wizz). The SSD drive is therefore only ever used as working space. I use a 120 GB SSD drive and never have it more than 60% full. If it last 10 years, I reckon I'm WELL in pocket, no question.
    Oh, and I'm still using SyncToy ! Works fine for me.

    My Toshiba 128 GB SSD only lasted me about 3 years before totally dying - lost everything on it and had to use an old backup so I don't accept what this guy says will last many years and maybe a decade. Keep regular restore points and especially full backups.

      LAST TRUMP 3 months ago +1

      +ExplainingComputers fair enough. I did get a second hand one and estimate its total lifespan so potentially could have been older than 3 years. Sad thing about SSD's is that no recovery at all worked unlike the old HDD's used to so have to be especially careful.

    • ExplainingComputers
      ExplainingComputers  3 months ago

      Sorry you lost your data. But I never said that *all* SSDs will last many years and maybe a decade. As the video discusses, it depends on how the drive is used, and all times cited are inevitably an average. I also noted that backups were vital! :)

      Capacities have increased, prices have fallen. But that's pretty much what manufacturers have focused on over increasing longevity. But the bigger drive you get, with the same data stored, the longer it will last.

    hi . 5:32 time of video . the subject of provisioning ..... is this why i hear people whining about why their 500 gb drive only shows roughly 470 gb ? Does this mean the ssd comes shipped with internal provisioning ? or is there another reason why the drive is slightly less than it's claimed capacity ... I've noticed this with regular hard drives as well in the past ....

    • ExplainingComputers
      ExplainingComputers  3 months ago

      In part over provisioning may cause this issue. But formatted capacities are always less than cited. And there is the GB vs GBi issue . . .
