TechPowerUp reviewed the Lexar NM610 1 TB M.2 NVMe SSD
A quote from the article:
Lexar's NM610 is built using a Silicon Motion SM2263XT controller, paired with Intel 3D TLC flash. The pseudo-SLC cache is rather large at 128 GB, which ensures big write bursts get handled at full speed. Pricing at $155, for a DRAM-less SSD seems a bit high though.Lexar NM610 1 TB M.2 NVMe SSD Review
