BobHoward posted:It's not as bad as those numbers might suggest, my friend who designed enterprise ssd chipsets and told me about this said that manufacturers rate flash for minimum guaranteed retention time at end of life, i.e. after doing the rated maximum write/erase cycles. A consumer SSD far away from wearout should remember data a lot longer than 1 year if left unpowered. Still, don't count on it, use HDDs for storage that might go unpowered a long time. For long time I've wanted to know, what is the failure mode when SSDs reach the maximum write cycle? I would hope that the available writable space slowly decreases, but the the blocks that can't be written on still remain readable? How much variation is there on how many cycles different blocks can be written? Could one block last only 1000 cycles, but the block right next to it manges 5000?

I doubt there is anything to think about. I don't think there is a Sata 3Gb/s SSD that is as good as the standard choices, yet cheaper enough to be worth buying.

It's no use wasting time pruning tabs. Computer performance grows faster than the load caused by all those tabs. Of course you can't do that on Chrome because gently caress horizontal tabs. So it's about 376 tabs for the default Firefox profile, 236 for the profile dedicated for Something Awful, 196 tabs for YouTube profile, 478 in the profile for all kinds of projects, latest about upgradijng and rooting my tablet, and then bunch of other profiles I don't have running currently.

Why do you think a more expensive memory technology with only a marginal improvement over NAND (in this application) will do better than, say, Seagate's SSHDs? (Which have been proving for quite some time that 8GB of cache isn't enough to make a HDD perform anything like a SSD, and that isn't likely to markedly improve with Optane or 16GB cache capacity.) Microsoft Studio is one product with similar system. 32 GB M.2 drive as cache with 1 or 2 TB storage drive.

Armacham posted:Update for my saga. I was able to borrow a spare 2.5" drive from someone and it was recognized fine. Guess I'll see if Samsung wants to try replacing it again without it disappearing for 3 weeks again. In the mean time I was able to convince dell to send me a new interposer cable for free. You could also try a USB-SATA adapter, that would eliminate any possible problems with the motherboard controller or SATA cable. Such an adapter could be useful to have around anyway. https://www.amazon.com/Anker-SATA-Portable-Adapter-Supports/dp/B014OSN2VW/ Knifegrab posted:Is there bootable software I can load onto a usb drive to confirm my suspicions that my ssd is toast? My bios attempts to detect it saying "Auto detecting SATA1..." but it hangs there for a while, then jumps to a "Please insert a boot drive, or restart" screen. It doesn't even show up in my bios or boot menu when all my others do. I have tried swapping cables too so that is not the issue. The opinion from others that this won't be fixed by different OS is most likely correct, but there are a multitude of different software that can be used for this. There are dozen different Linux distributions that can be used from USB stick without installing. Knoppix is a full desktop environment designed to be run only from CD or USB drive. System Rescue CD is a small Linux normally used from command line. Hiren's Boot CD is a large collection of different tools including HDD diagnostics, partition and disk management software and even a Windows XP PE that can be used from single USB drive. My suggestion is to have at least USB sticks with System Rescue CD and Hiren's Boot CD lying around permanently so you don't need to start creating them when the need arises.

Atomizer posted:The only thing I take issue with is the "...at some point in the next 5 years..." comment; 5 years is a long time in technology, and I wouldn't buy something now that I don't need until years down the line. I mean in SSD technology alone, imagine if you were stuck now using something you bought 5 years ago (like the aforementioned 840 Evo!!!) instead of something modern, cheap, and good like an MX500 or WD Blue (NVMe wasn't even a thing back then, and 5 years from now we might've transitioned to u.2 or whatever.) I interpreted that as "what to do with the old M.2 SATA after you replace it with NVMe." Currently the smart money would be with 500GB M.2 SATA or something, but in 3 years the price and performance probably change enough that you want to upgrade to a 1-2TB NVMe. Many systems have only one M.2 slot, so at that point the old M.2 SATA becomes useless, unless you happen to have some other system with empty M.2. If you had bought a traditional SATA you could still keep using the drive. From time to time I have an itching to upgrade to a 1TB SATA SSD for more space and an extra incentive for that is that I could my old 850 Evo in my Playstation 3. Like my old OCZ drive ended up in the ancient laptop I got as a hand-me-down. SATA is an universal standard, but M.2 SATA is already practically obsolete.

jeff8472 posted:Pulled the drive and re-seated it and it booted fine. Should I be worried it will go out again? Well, the sad thruth is, yes. You should never trust a storage drive, whether ancient spinning rust or the hottest NVMe. They are highly reliable, but still they are only waiting for the perfect moment to stab you in the back. Thankfully you seemed to already have a one part of the solution, your NAS. Instead of storing the important files in there how about putting a full backup of your computer in there, at least daily and possibly even more shorter intervals for the more important stuff. Duplicati and Duplicacy are probably one of the more popular choices for that. You say all your important files are in the NAS. Do you mean you have backups of those on the NAS, or is the NAS the only place those files are stored? Because the NAS can't be trusted either, it's just waiting to go up in smoke. Maybe set up a cloud backup for the NAS. Backblaze B2 or one of the multitude of competitors. My choice was a large harddrive installed in my work computer and daily rsnapshot of my home server.

repiv posted:It's not impossible but standardizing and shipping a compression codec and interface across all NVMe controllers (if drive-side) or Intel and AMD (if cpu-side) is going to take years. Don't hold your breath. I can't see how it would be that hard. Most useable place would probably be to have hardware or GPU assisted decompression in GPUs, since most games will probably have a lot of data to be fed to the GPU and this data is quite similar across large amount of games, so a single compression algorithm works for all of them. If you have advanced enough GPU the game can send the compressed data straight to it. If the GPU can't handle it but drivers are new enough, then the GPU driver uses CPU to decompress the data. If also the drivers are too old, them the game will have to do the decompression on CPU.

It probably has something to do with this line in the Arch wiki.quote:Warning: Users need to be certain that their SSD supports TRIM before attempting to use it. Data loss can occur otherwise! Kernel has a blacklist of SSDs with trim problems, but it hard to be sure if it includes all. Whitelist would be too much work with so many new SSDs and firmware revisions. For MacOS it would easy to whitelist the drives Apple has approved and Microsoft is big enough that SSD manufacturers have to maintain white- and blacklists for them.

Those drives are way overpriced, you probably want the WD SN550. The question is more about do you need more space. If you need a new drive anyway, then buying a good, cheap NVMe makes sense since they aren't much more expensive. Those premium NVMe rarely are worth the price.

Klyith posted:Can't be slower -- the whole point of a self-encrypting drive is that it's encrypting all user data 100% of the time. Every bit you read and write goes through the controller's AES accelerator. Only difference between protected vs plaintext is whether you set a password to protect the key. So any additional layer of encryption can only slow things down. Modern SSDs use encryption just for wear leveling. quote:It is a beautiful utterly elegant hack used to save on wear on the disk. Scrambling/randomising data on MLC drives also improves reliabilty on smaller process sizes - see this paper and these two referenced patents (here and here, and encrypted data is essentially random (thanks to alex.forencich for digging that up in the comments). In a sense AES encryption works the same way as the LSFR used to randomise data on a non encrypted ssd, only faster, better and simpler.

CaptainSarcastic posted:I've personally avoided Samsung SSDs just from the tech news about them I've picked up over the years. Needing to apply firmware updates to resolve bugs, address performance issues, poo poo like that - it was more than enough for me to not consider getting them even if they were priced the same as other drives. I would consider it worse sign if there are no firmware updates. At least the updates show that the manufacturer is willing to support their product. SSDs seem such a complex devices that I may still not trust manufacturers to get them right at first try. It doesn't happen even with expensive enterprise SSDs. We use a lot of HPE Proliant servers at work and I keep track of the firmware updates. Several SSD models had updates to fix a silly issue where they would die when they reach a lifetime of 32768 hours. Our VMware VDI got hit by an issue where the drive would die after you upgrade to VMware 7.0 unless you update the firmware. They didn't initially notice the requirement and then they had a drive die and found out about the update. I guess they didn't quite believe and assumed the death was more of a coincidense. And soon after another drive died and they realized all the drives must be updated immediately. That is such an incomprehensible issue for me. "If you upgrade your operating system, your SSD that has been working flawlessly for years will die within weeks."

god please help me posted:I heard someone on youtube say not to worry about it, since SSDs have a feature that supposedly makes them Read-Only once they can no longer have anymore data written to them. Is that true? Or is there some sort of data recovery service I can contact to help recover the data from a dead drive? There were some SSD models, I think from Intel, that had that feature. But that was basically a warning sign of your last chance to backup your data. If I remember correctly, the drives would go to read-only mode when they reached the warrantied write cycle limit. You would then have to backup the drive, because the next time you reboot the computer the drive would wipe itself and make data recovery impossible. The biggest irony is, that the drive itself might have been perfectly functional with a lot of life left, but when Intel considered it too used it would self-destruct. Just build a good backup system and forget all this drive longevity nonsense, because no drive can be trusted to hold your data. If you have good cloud of off-site backups you can still recover your data even if your house burns down.

Thunk posted:So a better option would be to get a big plug-in drive and do regular backups with it, and also make cloud storage copies of any really important documents? I can work with that. Thanks! It needs a bit of a consideration if an external drive or a NAS is better option. The biggest problem with the external is that it requires judiciously plugging it in and running the backup and then unplugging the drive. A NAS, at minimum a external drive plugged in to a router or some other always-on device would automatic backup. The problem with the NAS is that it is always online and under some risk, if you get a crypto ransomware on you computer it might be able to encrypt the NAS too. But it may be possible to hide the NAS enough that the average ransomware won't find it.
