... some vendors have been found tampering with SMART data which can be done on certain models ...
In the post-chia[1] landscape, I would advise extreme caution in sourcing drives and a decent shortcut is to not buy from Amazon ...

- dehrmann 1y agoI recently bought some 8TB SSDs that were obviously Samsungs, but had no serial or capacity label. They came at a steep discount, so some shenanigans were expected, and they're in a mirrored setup, so my data is safe-ish. I just have no idea why they're missing the labels.

- pessimizer 1y agoFirst thing I (and a lot of people) do with a drive is encrypt the volume and write zeros to the entire thing. Otherwise, you're leaking information about how much is on them after you encrypt them for your own needs. Once they've been "erased" they're ready to use (or give away to friends.) edit: of course who knows what's on the hardware, but I haven't heard of the exploit that would doom me.

- ACCount37 1y agoSSDs and USB flash drives in particular are full of sketchy NAND flash chips. Some of those chips are straight up salvaged from other electronics. Some are "known bad" chips, hanging in by a thread while the flash controller is fighting to sweep all the bad blocks under the rug. Some are dead MicroSD cards - with the dead MicroSD controllers bypassed to access the NAND die directly. NAND flash chips are "everything but the squeal" of electronics. There is a lot of chips that "somewhat work", and a lot of people trying to "upcycle" them into something that works long enough to be sold.
- MadnessASAP 1y agoIs Chia particularly harder on drives then other typical uses? Speaking as someone who wouldn't say no to a stack of cheap, used, multi-TB drives.
- rsync 1y agoIt’s not that Chia is more intensive than any other high usage activity… Rather, it is a combination of a highly intensive use case and a relatively morally bankrupt user base that results in a supply chain full of burned out SSDs. I say relatively morally bankrupt… I am sure there are many delightful people out there mining Chia coin …
