Capacity and audience

The SanDisk WDS400T1XHM-00CMT0 is a 4TB M.2 2280 NVMe SSD that connects through a PCIe 5.0 x4 interface. It targets enthusiasts building gaming PCs or workstations who need maximum sequential throughput and high random IOPS for large game libraries and content-creation workloads.

Build and thermal design

The drive ships with an integrated heatsink that helps sustain peak performance during extended heavy loads. Its M.2 2280 form factor fits standard motherboard slots, while the DRAM-less architecture uses SLC caching to deliver up to 14900 MBps read and 14000 MBps write without a separate DRAM package.

Upgrade context

This model replaces earlier PCIe 4.0 NVMe drives when a platform supports Gen 5 and the workload can use the extra bandwidth. The jump is worth it for users moving large assets or training AI models who need the 2400 TBW endurance rating and 1,750,000-hour MTTF for long-term reliability.
