There's simply no real value in looking at historic bad models as a 
guide to future performance (or the opposite). I can remember entire 
lines of hard drives from reputable manufacturers which were plauged by 
premature failures to the point that I replaced some multiple times 
under warranty before pulling them all (e.g., the IBM Deskstar 75GXP). I 
can also remember SSDs which had problems with repeated file corruption 
(OCZ Vertex, the only SSDs I ever saw reliably corrupt stored data). 
Bottom line is that sometimes you'll get a dud, and it doesn't really 
matter if you had a positive (or negative) experience with a 
superficially similar product decades ago. The Samsung 980 pros with the 
bad firmware were a ticking time bomb, but they haven't been sold with 
that version for years, and they haven't had issues since the fix. Other 
Samsung SSDs have been fine. The 860s have relatively low write 
endurance, but that's why they're as cheap as they are. You can either 
avoid using them in write-intensive settings and get a drive advertised 
for that role, or you can dramtically underprovision to lower the write 
cycle of individual cells and create space for caching. That's true for 
most low-cost drives, which is why they're low-cost, and why 
high-write-cycle drives are fantastically expensive. The average 
consumer will never write enough data to matter, but it is possible in 
pathological cases if something on the system goes nuts and starts 
sync-writing a really large number of small blocks.
