The MSI Spatium M570 HS is a solid-state drive in the M.2 2280 form factor, launched in 2022. 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 M570 HS interfaces using a PCI-Express 5.0 x4 connection. The SSD controller is the PS5026-E26 from Phison, a DRAM cache chip is available. MSI has installed 232-layer TLC NAND flash on the Spatium M570 HS, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are absorbed more quickly. The cache is sized at 670 GB, once it is full, writes complete at 5000 MB/s. Copying data out of the SLC cache (folding) completes at 1200 MB/s. Thanks to support for the fast PCI-Express 5.0 interface, performance is excellent. The Spatium M570 HS is rated for sequential read speeds of up to 10,000 MB/s and 10,000 MB/s write; random IO reaches 1400K IOPS for read and 1500K for writes.
The SSD’s price at launch is unknown. The warranty length is set to five years, which is an excellent warranty period. MSI guarantees an endurance rating of 1400 TBW, a typical value for consumer SSDs.
