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 Pro Frozr, 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 440 GB, once it is full, writes complete at 3600 MB/s. Copying data out of the SLC cache (folding) completes at 1800 MB/s. Thanks to support for the fast PCI-Express 5.0 interface, performance is excellent.
