WD Black SN770M M.2 2230 SSD Now Available – Best for Handheld Gaming Devices

Western Digital recently released its latest storage solution for handheld gaming devices like the Asus ROG Ally and Steam Deck – the WD Black SN770M M.2 2230 SSD. Not to be confused with the SN770 (non-M), which is a full-sized 2280 M.2 SSD, the SN770M measures only 22mmx30mm. However, despite its tiny form factor, the SN770M is capable of up to 5,150MB/s sequential read and 4,850MB/s sequential write speeds. WD also offers a 5-year limited warranty or up to the TBW of the drive, depending on its capacity. Speaking of the capacity, the WD Black SN770M is available in 500GB, 1TB, and 2TB capacities. All are available now, and you can check out more details, including where to get one, from WD’s official news release below.
