So I'm confused. I get the wear out level not going lower than 1%, but that doesn't mean the drive failed, right?

- craftyguy 8y agoI think technically it might still work (i.e. you could read/write to it without errors?), but the integrity of the data it is storing would be questionable.
- sebazzz 8y agoDoesn't it only mean that writes will fail?
- solotronics 8y agoI would think it would mean that your writes may be corrupted.
- wmf 8y agoSome SSDs go into read-only mode when they have used up their endurance but others will let you keep writing.
- kalleboo 8y agoIt should but due to crappy firmware many SSDs will just drop off the bus and become unreadable.
- mjb 8y agoThat's very dependent on the drive vendor, model, and even firmware version. In many cases, drives can go on working for a very long time after the SMART metrics show it has failed. Whether you want to take the "risk" depends a lot on how critical this particular device is in your infrastructure.
- tenebrisalietum 8y agoI have a 16GB SSD that used to be in a POS terminal before I bought it second hand. The SSD Wear Leveling Count attribute shows as failed. Still works. I have chosen to use it as part of a RAID1 for an OS install on a home server. Waiting to see how long it will last.
- WrtCdEvrydy 8y agoIt's kinda like the expiration date for foods, an estimate.

- rb2k_ 8y agoIn production tests I've seen the synthetic "wear out level" go down to 1% and the machine still writing Petabytes of data without any issues. That being said, I would only do that on machines that are mostly disposable :)
