The Lexar NM610 Pro is a solid-state drive in the M.2 2280 form factor, launched in 2023. It is available in capacities ranging from 500 GB to 2 TB. This page reports specifications for the 500 GB variant. With the rest of the system, the Lexar NM610 Pro 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 Pro, 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 Pro is rated for sequential read speeds of up to 3,300 MB/s and 1,700 MB/s write.
The SSD's price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. Lexar guarantees an endurance rating of 120 TBW, a relatively low value compared to other SSDs.

Notes

Drive:

Controller and NAND Flash might be different

Controller:

The difference between this and the non-XT revision (SM2263, SM2263G, SM2263ENG, etc.) is that this revision doesn't support the DRAM cache, in fact it uses HMB (Host Memory Buffer).
