Corsair MP700 ELITE CSSD-F4000GBMP700ENH 4TB M.2 2280 internal SSD

4TB PCIe 5.0 NVMe SSD

The Corsair MP700 ELITE CSSD-F4000GBMP700ENH is a 4TB internal solid-state drive built on the PCI-Express 5.0 x4 interface with NVMe 2.0 protocol. It uses a Phison PS5031-E31T controller and 3D TLC NAND to deliver up to 10000 MBps sequential read and 8500 MBps sequential write speeds. The drive includes AES 256-bit encryption and is rated for 2400 TBW. It ships without a pre-installed heatsink.

Suits high-throughput builds.

This drive targets enthusiasts and professionals moving large datasets, compiling code or loading massive game libraries who can provide active motherboard or add-in cooling. The lack of an included heatsink means the builder must ensure adequate airflow or a compatible M.2 shield. Systems restricted to PCIe 4.0 slots will operate at Gen4 speeds, and compact laptops with no thermal headroom should consider lower-power alternatives.

Sustained writes hold near peak with proper cooling

Under continuous heavy write workloads the Phison controller maintains performance close to the 8500 MBps sequential figure provided the NAND temperature stays within spec. Random write IOPS of up to 1400K remain consistent during extended mixed I/O once the SLC cache is saturated. Without sufficient cooling the controller will throttle to protect the 3D TLC memory, reducing both sequential and random throughput until temperatures drop.
