The WD_BLACK SN7100 2TB is a PCIe Gen4 NVMe SSD in the M.2 2280 format, now sold in SanDisk’s refreshed “powered by SanDisk” packaging. SanDisk rates the 2TB model at up to 7,250 MB/s sequential read and 6,900 MB/s write, with up to 1,000K random read and 1,400K random write IOPS, which puts it near the top of the Gen4 class for a drive without its own DRAM cache. Rated endurance is 1,200 TBW.

Gen4 speed for gaming PCs and handhelds
At 7,250 MB/s the WD_BLACK SN7100 2TB reads about thirteen times faster than the 550 MB/s ceiling of a SATA SSD, so large game installs, level loads and texture streaming finish quickly. SanDisk says the SN7100 is up to 35% faster than the previous generation and up to 100% more power efficient, which matters in gaming laptops and handheld PCs, where every watt affects battery life. The drive uses host memory buffer (HMB) instead of onboard DRAM, a design that keeps power and heat down while holding high sequential speeds.

Slim enough for laptops and handhelds
The drive measures 80 x 22 x 2.38 mm and weighs 5.8 g, so it fits laptop and handheld M.2 slots where thicker drives or heatsinks do not. It runs at full speed in a PCIe Gen4 x4 slot and also works in Gen4 x2, Gen3 and Gen2 slots at their lower speeds. SanDisk rates the operating temperature from 0 to 85°C.
Sandisk Dashboard and Game Mode
On Windows, the free Sandisk Dashboard shows drive health, remaining life and temperature, installs firmware updates and offers Game Mode, which keeps the WD_BLACK SN7100 2TB ready for peak performance while you play. Its 1,200 TBW rating means you could write 300 GB every day for more than ten years before reaching the rated endurance.

Using it in a PS5
Sony recommends a PCIe Gen4 M.2 drive of 5,500 MB/s or faster for the PS5 expansion slot, and the WD_BLACK SN7100 2TB exceeds that figure. SanDisk does not list the PS5 on its product page, and the drive has no heatsink, so for a PS5 you need to add a heatsink or cooling structure that fits within Sony’s size limits.
Who This Is Not For
This is a bare M.2 drive, so it needs a free M.2 2280 slot; older PCs with only SATA ports cannot use it. It has no DRAM cache, so very long sustained writes, such as copying hundreds of gigabytes of video at once, can slow down once the fast cache fills, and workstation users moving terabytes a day may prefer a drive with DRAM. Sandisk Dashboard runs on Windows only. SanDisk is also moving this line to the SANDISK name, so packaging may differ from older WD_BLACK photos.

FAQ – WD_BLACK SN7100 2TB
Is WD_BLACK SN7100 2TB an original sealed product?
Yes. Every WD_BLACK SN7100 2TB we ship is original Western Digital stock, new and sealed in its retail box, never a refurbished or opened unit.
Can I use the WD_BLACK SN7100 2TB in a PS5?
Yes, it exceeds Sony’s 5,500 MB/s recommendation for the PS5 M.2 slot, but you must add a heatsink or cooling structure. SanDisk does not list the PS5 on its product page.
Does it work in a PCIe Gen3 motherboard?
Yes. It is backward compatible with Gen3 and Gen2 slots, at those slots’ lower speeds.
Does it have DRAM?
No. It uses host memory buffer (HMB), which borrows a small amount of system memory.
Is a heatsink included?
No. The WD_BLACK SN7100 2TB is a bare M.2 2280 drive without a heatsink.
How much data can I write to it?
1,200 TB of rated endurance (TBW), according to SanDisk.
