SSD Failure Rates?

[dave_the_nerd]

Has anybody done an SSD failure study similar to the old Google study from a few years back? (Or the more recent one from Backblaze.)

My 90GB Vertex 3 is approaching two years old (so I know I'm past the "cradle death" phase, OCZ or not), and SSDLife is still reporting 100% health and a projected failure date in 2021. But I know that's just a reflection of write wear on the NAND.

IIRC, 3yrs old was when the failure rate of spinner HDDs started to tick upwards. So I'm curious if there's a similar time frame for SSDs, since they've been out for a good 5+ years now and somebody ought to have some actual data.

Complicating matters is that there has been so much crazy-fast change in SSDland. Is the reliability of a SSD from 5 years ago really comparable to or indicative of one from today?

It depends quite a lot on the write cycles. Any test from a large farm would tend to be testing a far higher write cycle than the typical home use scenario.

Keep using it, make regular backups... same safe practices as always. Since there are no moving parts there is no finite life expectation for an SSD besides write wear or random power surge or PSU failure inflicted damage.

Same as a PC component like video card or mobo. gl

No one can say out a certain model. Every firm had some stabile series, also the unstabile.

Currently, Corsair Neutron GTX and Samsung 840 Pro looks well.

But if you desire to get most reliable ones, got to look at enterprise grade solutions.
