The Corsair MP600 Core XT is a solid-state drive in the M.2 2280 form factor, launched on April 25th, 2023. It is available in capacities ranging from 1 TB to 4 TB. This page reports specifications for the 2 TB variant. With the rest of the system, the Corsair MP600 Core XT interfaces using a PCI-Express 4.0 x4 connection. The SSD controller is the PS5021-E21T from Phison, a DRAM cache is not available. Corsair has installed 176-layer QLC NAND flash on the MP600 Core XT, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are processed more quickly. The cache is sized at 466 GB. Copying data out of the SLC cache (folding) completes at 100 MB/s. Thanks to support for the fast PCI-Express 4.0 interface, performance is excellent. The MP600 Core XT is rated for sequential read speeds of up to 5,000 MB/s and 4,400 MB/s write; random IOPS reach up to 700K for reads and 1000K for writes.
At its launch, the SSD was priced at 115 USD. The warranty length is set to five years, which is an excellent warranty period. Corsair guarantees an endurance rating of 450 TBW, a relatively low value compared to other SSDs.
