Lexar has introduced its new lineup of M.2 SSDs. The Lexar Professional NM800 drives achieve sequential read and write speeds of up to 7.4 and 5.8GB/s, depending on the variant. The SSDs also get a thin heat spreader made of graphene.

The Lexar Professional NM800 will be in M.2 2280 format and will come in variants with 512GB and 1TB storage capacity, Cowcotland writes. The SSDs get tlc-nand and use an unknown NVMe 1.4 controller and a PCIe 4.0 x4 interface.

The 1TB variant achieves sequential read and write speeds of up to 7.4GB/s and 5.8GB/s. The random read speed is 450,000 ips and the random write speed is a maximum of 750,000 ips. The 512GB model achieves slower speeds, with a sequential read speed of 7GB/s and a sequential write speed of 3GB/s. The random read and write speeds of the 512GB variant are 200,000 and 550,000 iops respectively.

Tom’s Hardware further writes that the NM800 SSDs will be equipped with a graphene heat spreader, which is thin and therefore suitable for use in laptops. The endurance is according to Lexar a maximum of 500TBW with a mean time between failures of 1.5 million hours and 0.44 drive writes per day. The 512GB variant costs 100 euros and the 1TB model has a suggested retail price of 180 euros.
