SN770M 1TB M.2 2230 NVMe SSD
The WD_BLACK SN770M is a 1TB M.2 2230 NVMe drive built for handheld gaming devices and compatible laptops. It uses PCIe Gen 4.0 and 3D NAND TLC to deliver sequential reads up to 5150 MBps and writes up to 4900 MBps. Random performance reaches 740000 read IOPS and 800000 write IOPS.
Installation fits M.2 2230 slots
The single-sided 2.38mm height matches the tight clearance inside devices such as the Steam Deck, ROG Ally and many Surface models. No heatsink is included, so thermal throttling can appear under sustained heavy writes in fanless chassis. Western Digital Dashboard on Windows helps monitor health and update firmware.
1TB capacity with 600TBW endurance
The 1TB model stores dozens of large titles and leaves headroom for OS updates and saves. Rated at 600TB written and 1.75 million hours MTTF, it handles typical gaming workloads for years. Workloads that exceed the TBW rating or sustained writes beyond the thermal limits of the host device will reduce lifespan.

この商品に関する質問
How do I confirm the SN770M is hitting 5150 MBps read and 4900 MBps write after install?
Run CrystalDiskMark or a similar NVMe benchmark on Windows; sequential results should approach 5150 MBps read and 4900 MBps write on a PCIe 4.0 slot, while the Western Digital Dashboard reports drive health and firmware status.
What ships in the WDBDNH0010BBK-WRSN retail box and what must I source separately?
The box contains only the 1 TB M.2 2230 SSD; you must supply a compatible M.2 2230 slot, a motherboard standoff and screw, and a heatsink if your device requires one.
Which capacity of the SN770M M.2 2230 line should I pick for a Steam Deck upgrade?
The 1 TB model delivers 5150 MBps read, 4900 MBps write, 600 TBW and 1.75 million hours MTTF — choose 2 TB only if you need more space and your device accepts the same 2230 form factor.
