The Lexar NM610 is a solid-state drive in the M.2 2280 form factor, launched in 2020. It is available in capacities ranging from 250 GB to 1 TB. This page reports specifications for the 500 GB variant. With the rest of the system, the Lexar NM610 interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the SM2263XT from Silicon Motion, a DRAM cache is not available. Lexar has installed 64-layer TLC NAND flash on the NM610, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly. The NM610 is rated for sequential read speeds of up to 2,100 MB/s and 1,600 MB/s write; random IOPS reach up to 188K for reads and 156K for writes.
At its launch, the SSD was priced at 70 USD. The warranty length is set to three years, which is above average, but shorter than the five years offered by many other vendors. Lexar guarantees an endurance rating of 250 TBW, a typical value for consumer SSDs.
