Lexar rates it at up to 7,400 MB/s sequential read and 6,500 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 Lexar NM790 1TB have a DRAM cache?+

No. It has no DRAM cache (DRAM-less (HMB 3.0)), which keeps power and heat low; sustained heavy writes are slower than on DRAM drives.

What warranty does the Lexar NM790 1TB have?+

5 years or until the rated 1,000 TBW is written, whichever comes first (per Lexar).
