Awesome price on the 2TB and a bit of a small price drop on the 1TB compared to the most recent Amazon deal if you're after a PCIe 5 SSD.
On the technical side it offers PCIe 5x 2 and PCIe x4 support with a sequential read up to 5000MB/s, sequential write up to 4200MB/s, HMB, 600TBW (1TB), 1200TBW (2TB) and uses Samsung TLC 133 layer flash memory.
pcie 5x2 is the same speed as 4x4, this is basically a marketing gimmick from samsung, given that this ssd is worse than a lot of the pcie 4.0 ssds
