WD_BLACK SN7100 1TB for gaming laptops

The WD_BLACK SN7100 is a 1TB internal SSD built for serious on-the-go gamers who need responsive storage in a compact M.2 2280 form factor. It uses a PCI-Express 4.0 x4 interface and NVMe protocol with Western Digital TLC 3D NAND to deliver high throughput for modern titles. The drive is optimised for laptops and handheld devices where power efficiency matters.

1TB capacity with 7250 MBps read and 6900 MBps write

Sequential speeds reach up to 7250 MBps read and 6900 MBps write, while random performance hits up to 1000000 IOPS read and 1400000 IOPS write for snappy game loads and asset streaming. The 600TB TBW rating and 1750000 hour MTBF provide ample endurance for gameplay captures and content creation. A DRAM-less design uses HMB to maintain speed without extra power draw.

M.2 2280 build with 95mW active power

Average active power sits at 95mW and maximum operating power at 4.5W, offering up to 100% better efficiency over the previous generation for longer battery life. Sleep power drops to 5mW in PS4 state. The single-sided M.2 2280 layout fits thin chassis without clearance issues. WD_BLACK Dashboard on Windows lets you monitor health and keep firmware current.

Questions about this item

Will the WD_BLACK SN7100 M.2 2280 work in a laptop that only has a PCIe 3.0 slot?

The drive is PCIe 4.0 x4 but will fall back to PCIe 3.0 speeds in an older slot, so it functions normally while you keep the existing laptop.

How can I verify the SN7100 is delivering the advertised 7250 MBps read and 6900 MBps write after installation?

Run a standard NVMe benchmark such as CrystalDiskMark on Windows; sequential results should approach 7250 MBps read and 6900 MBps write on a PCIe 4.0 platform.

Does the WDS100T4X0E-00CJA0 package include a heatsink or mounting screw, or must I buy them separately?

The retail box contains only the M.2 2280 SSD; any heatsink or motherboard standoff screw must be sourced separately.
