Key strengths
Rated up to 7,250 MB/s sequential read and 6,300 MB/s sequential write, with up to 1 million random read and 1.35 million random write IOPS.
Runs over PCIe 4.0 x4 or PCIe 5.0 x2 and also works in PCIe 3.0 x4 slots, with TLC V-NAND and a five-year warranty covering up to 1,200 TB written.
Before you buy
Its PCIe 5.0 mode uses two lanes rather than four, and rated speeds top out at 7,250 MB/s read and 6,300 MB/s write.
Samsung specifies Host Memory Buffer caching and lists no onboard DRAM for this drive. Peak write speed relies on the TurboWrite cache, and Samsung does not list a post-cache write speed for this model.
