Thread-topic: [CRTech] SSD failure modes (TRIM)

Biggest enemy of SSDs (in XP and earlier environments) is defragging. Defragmentation processes need to be completely off, and never run. They’ll put an enormous amount of unnecessary wear on the drives and pull the useful life way down. SSDs do their own file fragment management stuff and that is all they require.


Regarding seeing this issue repeatedly, I’d question power quality, either in the location they’re being used (poor or incorrect grounding) or in the means by which they are being fed (power supply, regardless of whether cord-wart or internal). I’ve never had an SSD drive even error on me, much less fail, in a wide variety of applications and use environments for both personal use and client use in the last 4 or 5 years that I’ve been using them.


I’d also, once again, warn against cheap/off-brand SSD drives… stick with one of the better rated drives (Samsung is my go to, SanDisk and Hynix are well regarded). The no-name, low- tier, and licensed-name drives are all coming from factories that are recapturing chips and boards that didn’t pass various QC tests, slapping it together and selling it cheap. There’s a reason it was rejected by the big guys. Going “low-price” in SSD purchasing is probably the single worst thing modern computer users/builders could do (other than maybe buying no-name “oem” labelled knockoff laptop chargers from ebay!). Just say no!

True.  Some drives (from Crucial, for example), have “background garbage collection” functionality that can do the same thing as TRIM; both of these, though, don’t really affect the life of the drive, only the slowdown problem caused by the drive having to clear data blocks before it can write to them.  Funnily, there are some interesting requirements for these garbage collection things.  I saw a post from Crucial that said you ought to leave the computer in the system BIOS menu for 6-8 hours periodically to trigger it. J


But yes, the TRIM / XP issue doesn’t affect drive lifetime, only performance.

Curious... I thought that the built-in drive controller chipset already handled "wear-leveling" internally and transparently to the user.

I did do a little research, and the common failure mode for over-used NAND blocks, is that files will become "READ ONLY"... thus, allowing you to still retrieve them for backup/copy to a new drive. It would have been nice if THAT was the failure mode, here... my backups were good, but older, so a small amount of data was lost.

Gotta make more current backups, more often. ;)

While Windows XP doesn’t provide support for TRIM, there are a number of software solutions that can use TRIM to optimize your SSD in XP.  For example, Piriform’s Defraggler: https://www.piriform.com/docs/defraggler/technical-information/defraggler-and-ssds
