I had a 960 GB Sandisk Ultra ll just die on me. It was within warranty and they just replaced with an 1 TB Ultra 3D.
Not a great indicator, but Amazon reviews seem for rate most SSD brands at 4.5 stars or above.

I did look at the Ultra ll and they seemed to have more one star reviews than, the newest 3D Ultra. (4%)

The 960 GB Ultra ll I had has 13% one star
The 1 tb Ultra ll has 9% one star
The 480GB Ultra ll has 11% one star
The 240 BG Ultra ll has 7% one star
Maybe its possible that this line had issues. A look at the first link shows the lesser brands, SiliconPower,
Inland and even Adata with even higher 1 start reviews.
I am not sure of any predictor for failure, except maybe don't get the cheapest SSDs?
Samsung seems to generally have the least amount of 1 star reviews. They also cost more.
Stuff happens, and things break. Now if this replacement dies within a couple years then yes, I may rethink sansidk
but not based on one bad drive.
