How about the 4KQD1 and various random read/write performance?
Doubt we will see those improve on regular NAND much more. These should have minor improvements because the major issue seems to be latency and Samsung says they improved that, but we seem to be at limits in this NAND tech outside of accessing more in parallel to go ever higher. We really just need better and more accessible 3DXPoint, or another new tech that is "in the works" to see real improvement.
And as a reminder to everyone, these huge numbers like 5GB/s write speed this quotes are only for the SLC cache portion of the drive. When you start filling it or if you write for too long you move to regular TLC space and your speed will drop into the hundreds of MB just like sata drives have.

yeah baby! This is what I was waiting for. I was literally holding my breath for a 980 pro pie 4.0 m.2 for CES 2020.
Sign me up for a 2TB version plz!
I'm really surprised that the capacities, at least on the initial launch, are so low. I was expecting them to have a 2 and 4 TB version out the gates, but I guess the market is a little small still for them to throw that much capacity onto a PCIE 4.0 stick yet.
The only argument I can think of is that M.2 variants of Optane do not offer enough capacity, but their AIC variants seem to be doing fine.
All this talk of PCI-e 4.0 but none of them can touch even first gen Optane on randoms or latency.
To me, Optane/3DXpoint needs to double capacity while cutting cost in half and then it will be something useful to the masses. NAND is just finally at that sweet spot in pricing and size that until something else can match it, nothing will replace NAND. It has enough performance to be good enough while meeting all other criteria.
