I bought 5 of these less than two years ago, though they were the 500 GB model. Every single one of them has failed - some within 45 days and just outside the return period. The last one, which I honestly forgot was still running and thought I'd replaced, failed this morning.
These SSDs are absolute garbage and their warranty replacements are a joke (read: you're outta luck, Chuck). Burn me once, shame on you. Burn me 6 times, well, shame one me for buying them again, I guess. lol. I had one fail prior to this batch, but assumed it was an oddball.
Pro tip: Never buy Silicon Power (SP) SSDs. I you have any in use, make sure you have backups running daily and that you check those backups every so often.
Seems like the 3v3 regulator is what goes out on these, but I'm not going to bother trying to repair it since I've got backups.
Both batches from Amazon (months apart). I also bought one of that brand a few years ago (2017?) that ultimately failed within 2 years as well.
I said this in another comment, but best I can tell, the actual flash chips seem to be fine and it's the support circuitry (power regulator, SATA controller, etc) that seems to be failing.
I'd assume it's got something to do with the system you're using them on, some issue with power or something that better quality drives are able to handle, but not these.
These are cheap, yes, but if everyone ordering these was failing just outside the return period, they'd have far more 1 star ratings.
