You would have thought by now they would be pushing 3D Xpoint technology, guess they still have bugs to iron out in that. At least a small Optane cache instead of or on top of the SLC area these use.

Didn't they sell off their NAND dvision…?

Well they seem rather lacklustre, they're not particularly fast in iops or straight up read/write and to top it off they're not exactly cheap…
