Western Digital announces Black SN770M SSDs with up to 2 TB capacity for Steam Deck and Asus ROG Ally consoles
The default storage capacities for the Steam Deck handheld console are starting to feel a bit antiquated when quite a few current and upcoming games require more than 100+ GB. The Asus ROG Ally has a single 512 GB option, but even this one might still feel on the low side. Luckily, Western Digital is now offering capacity upgrades up to 2 TB for both consoles, and price points are decent.
WD’s new Black SN770M SSDs come in the M.2 2230 reduced form-factor with 30 mm length so they can easily fit in the Deck and Ally handhelds. Capacities range from 500 to 2 TB and they feature the PCIe 4.0 interface with up to 5,150 MB/s sequential read speeds plus up to 4,900 MB/s sequential writes, and 740K random read IOPS / 800K random write IOPS.
The 1 TB version appears to be the fastest, but the 500 and 2 TB are just slightly slower. On the other hand, the 2 TB version has the best endurance rated at 1,200 TBW, while the 1 TB is rated for 600 TBW and the 500 GB one is good only for 300 TBW. All models get a 5-year warranty.
Price-wise the 500 GB model is listed at US$74.99, whereas the 1 TB variant costs US$109.99 and the 2 TB US$2019.99. The 500 GB and 1 TB models will be available within 1 week, yet the 2 TB one has no availability for now.
