SSD Torutre Test Wraps

Techreport's long running SSD failure torture test has wrapped up. A Samsung 840 Pro 256 GB survived 2.4 PB or data written to it. That's a disk capacity wear multiplier of 2.4 x 10^6 GB/256GB ~ 1,000 times (e.g. you can fill and erase the whole disk about 1,000 times).

Overall a very impressive wear result for SSD drives. And while it's nice that my favorite brand SSD came out on top with their Samsung 840 Pro (although the 840 Evo died early), I'd not read too much into the results of individual drives beyond that SSDs can take a good write beating and keep going...

And I have several concerns with how all this was done, including uh a horribly silly sample size (just one drive of each type for most of the drives) you need a much larger sample set to start with to make useful comparisons. But it s an interesting first go, and I'd hope reviewers do much more of this type of testing, and dig into things like SSD wear failure modes and failure warning/detection etc.



And all tests were done with TRIM enabled (you'd' be nuts to bother looking at SSD wear tests without using TRIM).



And remember these are just consumer spec drives, if you need more impressive results there are enterprise/server class SSD drives available.



Be careful assuming a spinning HDD has infinite write lifetime, they don't wear on writes like an SSD, but they suffer mechanical and electrical failures. Components wear if just left spinning, but also don't like being powered up and down, and really hate being bumped or dropped...
