The MSI Spatium M370 is a solid-state drive in the M.2 2280 form factor, launched on July 5th, 2021. It is available in capacities ranging from 1 TB to 2 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the MSI Spatium M370 interfaces using a PCI-Express 3.0 x4 connection. The SSD controller is the PS5015-E15-35 from Phison, a DRAM cache is not available. MSI has installed 96-layer TLC NAND flash on the Spatium M370, the flash chips are made by Toshiba. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The Spatium M370 is rated for sequential read speeds of up to 2,400 MB/s and 1,850 MB/s write; random IO reaches 220K IOPS for read and 330K for writes.
At its launch, the SSD was priced at 240 USD. The warranty length is set to five years, which is an excellent warranty period. MSI guarantees an endurance rating of 1600 TBW, a typical value for consumer SSDs.
