PCIe 5.0 x4 NVMe drive

The SanDisk WDS100T1XHM-00CMT0 is a 1TB internal SSD built for consumer desktops and workstations. It uses the M.2 2280 form factor with a PCI-Express 5.0 x4 interface and NVMe protocol. A 1GB DRAM cache supports sustained throughput for gaming, content creation and AI model loading.

Thermals and power

An integrated heatsink helps maintain performance during extended workloads. Active power draw reaches 6.2W during reads and 7.0W during writes, while idle sleep state drops to 5 mW. The drive operates from 0°C to 85°C.

Build and connectors

The single-sided M.2 2280 module fits standard motherboard slots and includes the heatsink in the same profile. Rated for 600TB written and 1750000 hours MTTF, the TLC 3D NAND is backed by the WD_BLACK Dashboard for health monitoring and Game Mode 2.0 on Windows.

Questions about this item

Will this M.2 2280 drive with its included heatsink fit in my laptop or small-form-factor desktop?

The drive uses the standard M.2 2280 form factor, but the attached heatsink adds height; verify your device has enough clearance above the M.2 slot before installing.

Does my motherboard need PCIe 5.0 to use this SSD, and what speeds will I see on PCIe 4.0?

The SSD works in PCIe 4.0 and 3.0 slots, though sequential read and write speeds will be limited to the slot's maximum bandwidth rather than the drive's rated 14900 MBps read and 11000 MBps write.

Is the 1 GB DRAM cache and 600 TBW rating sufficient for heavy gaming and content-creation workloads?

Yes, the 1 GB DRAM cache helps sustain high random performance up to 1600000 read and 2400000 write IOPS, while the 600 TBW endurance rating supports extensive daily writes over the drive's 1750000-hour MTTF lifespan.
