I've seen Samsung, Hynix, Crucial, and Sandisk go bad. None of my personal ones have gone bad, but I did have one no-name for my Chromebook that was just buggy (it would work fine for a few months, corrupt, be fine after re-partitioning, then repeat after a few more months...). It's rare for any current day SSD to die within its service life, and it's definitely rarer than HDDs in general, but *^%# happens. I've seen more Sandisks than any other, but an important thing to take into account there is that Sandisk and Samsung account for a vast majority of SSDs that I or my work have bought and installed, so I don't think it's fair to bash them over a couple going bad, instead of just one of another brand.
