Sandisk (WD) rates it at up to 7,250 MB/s sequential read and 6,900 MB/s sequential write on a PCIe Gen 4 slot. Real-world speed depends on the motherboard slot and the workload; in an older PCIe slot it runs at that slot's lower limit.

Does the WD_BLACK SN7100 2TB have a DRAM cache?+

No. It has no DRAM cache (DRAM-less), which keeps power and heat low; sustained heavy writes are slower than on DRAM drives.

What warranty does the WD_BLACK SN7100 2TB have?+

5 years or until the rated 1,200 TBW is written, whichever comes first (per Sandisk (WD)).
