I wonder how representative the Extreme portable drives are to their SD cards. SanDisk cards have always been extremely reliable. I assume the Extreme drives are fabricated in a different factory or even outsourced to some random Shenzhen plant. Worrying is the idea that they’ve done the same with SD cards.
All the more reason for them to be transparent, name the problem, remove the affected stock from sale, set up some kind of recovery and/or compensation service, and write off the loss. Otherwise “SanDisk” will mean “you have shit on your shoe” forever. In the storage space a brand has to mean “safe” or its dead.
Maybe they are still finding the edges of the problem. Maybe.
I’ve owned SanDisk for years, before 2016 and after. I haven’t seen a quality difference in the products I use but I also haven’t personally owned this Extreme drive. Flash memory used to have abysmal lifespans, like really bad at long-term storage. Makes me wonder if these Extreme drives are using old tech to save WD their bottom dollar.
These failures don’t have to do with where they’re manufactured - it seems like this is some sort of firmware bug. NAND doesn’t really just choose to wipe itself at random. Actual NAND chip failures are few and far-between, so this is very likely much more than a hardware issue.
That said, I personally have done a lot of testing with WD-manufactured NAND, compared other companies’ NAND - and the WD NAND is pretty crap. I can’t really go into further details than that, though.

We assume WD isn’t outsourcing their firmware engineering. That could explain why they’re so quiet.
