The Corsair MP700 Pro SE Hydro X is a solid-state drive in the M.2 2280 form factor, launched on May 9th, 2024. It is available in capacities ranging from 2 TB to 4 TB. This page reports specifications for the 4 TB variant. With the rest of the system, the Corsair MP700 Pro SE Hydro X interfaces using a PCI-Express 5.0 x4 connection. The SSD controller is the PS5026-E26 from Phison, a DRAM cache chip is available. Corsair has installed 232-layer TLC NAND flash on the MP700 Pro SE Hydro X, the flash chips are made by Micron. To improve write speeds, a pseudo-SLC cache is used, so bursts of incoming writes are handled more quickly. The cache is sized at 440 GB, once it is full, writes complete at 4000 MB/s. Copying data out of the SLC cache (folding) completes at 1500 MB/s. Thanks to support for the fast PCI-Express 5.0 interface, performance is excellent. The MP700 Pro SE Hydro X is rated for sequential read speeds of up to 14,000 MB/s and 12,000 MB/s write; random IO reaches 1700K IOPS for read and 1600K for writes.
The SSD's price at launch is unknown. The warranty length is set to none, which is quite short for the SSD industry. Corsair guarantees an endurance rating of 3000 TBW, a very low value compared to other SSDs.
