Manufacturer description
The WD_BLACK SN7100 2TB is a PCIe Gen4 M.2 2280 NVMe SSD built for gamers who play away from the desk. Sequential speeds reach 7,250 MB/s read and 6,900 MB/s write on the 1TB and 2TB models, which Sandisk rates as up to 35% faster than the previous WD_BLACK generation. The bigger story for handhelds is efficiency: the SN7100 claims up to 100% more power efficiency than its predecessor, so a Steam Deck, ROG Ally, or thin gaming laptop spends less of its battery feeding the drive and more of it running the game. The 2TB capacity gives you room for a modern library without constantly…
SpecPicks Verdict
SpecPicks scored Sandisk WD_Black SN7100 2TB NVMe SSD using a rating × review-volume × price-fit model applied to published specs and reviews across the ssds & storage category. Sandisk's ssds & storage lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Will the WD_BLACK SN7100 2TB fit a Steam Deck or ROG Ally?
It uses the M.2 2280 form factor that Sandisk markets for laptops and handheld gaming devices. Confirm your handheld's slot length, since some models take shorter 2230 drives.
How fast is the SN7100 2TB?
Up to 7,250 MB/s sequential read and 6,900 MB/s sequential write on the 1TB and 2TB capacities, which Sandisk rates as up to 35% faster than the previous generation.
Is it worth it if my motherboard only has PCIe Gen5 slots?
The SN7100 is a PCIe Gen4 drive and will run at Gen4 speeds in a Gen5 slot. You get full 7,250 MB/s performance but none of the extra Gen5 headroom.
Does it come with a heatsink?

What warranty does the SN7100 carry?
