WD_BLACK SN7100 2TB gaming SSD

The WD_BLACK SN7100 is a 2TB M.2 2280 solid state drive built for gamers who need fast storage in laptops or handheld devices. It uses a PCI-Express 4.0 x4 interface with NVMe protocol and TLC 3D NAND memory. The drive delivers sequential reads up to 7250 MBps and writes up to 6900 MBps.

Thermals noise and power draw

Average active power is 95mW with a maximum operating power of 4.5W, while sleep state drops to 5mW. The design targets up to 100% more power efficiency over the previous generation, which helps keep thermals low and battery life long in portable systems. No DRAM cache is present, relying on HMB instead.

Build quality connectors and mounting

The M.2 2280 form factor fits standard laptop and handheld slots without adapters. Endurance is rated at 1200TBW with an MTBF of 1,750,000 hours. The WD_BLACK Dashboard utility for Windows lets users monitor health and optimise performance. This drive is purpose built for mobile gaming workloads.

Questions about this item

How do I install the M.2 2280 drive in my laptop and what step do people often miss?

Insert the drive at an angle into the PCIe 4.0 x4 slot, press it flat and secure it with the motherboard screw; the step most people miss is enabling the NVMe controller in BIOS so the OS can see the drive.

What maintenance or replacement will the 2TB TLC 3D NAND drive need later?

No routine maintenance is required; the drive is rated for 1200TBW and 1750000 hours MTBF, so replacement is only needed if the endurance limit is reached or a hardware fault occurs.

What limit appears first during sustained heavy writes on this PCIe 4.0 x4 SSD?

The 4.5W maximum operating power ceiling is reached before thermal throttling engages, so sustained write speeds may drop to stay within the power envelope.
