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.

Source - I’m an SSD firmware engineer.
We assume WD isn’t outsourcing their firmware engineering. That could explain why they’re so quiet.
I’d personally be super surprised if they were outsourcing their firmware engineering - but I do suppose it’s technically possible.
