If you're looking at the ROG Xbox Ally (X), then you might want to consider the officially licensed storage for said devices. Announced at Tokyo Game Show, Sandisk is launching both MicroSD cards as well as internal NVMe SSDs as specific brand tie-ins for the new machines. The Sandisk MicroSD Card For ROG Xbox Ally (X) comes in capacities of 512GB, 1TB, and 2TB, while the WD_BLACK SN7100X is available in 2TB and 4TB sizes.
We'll start with the SSD, even though it's not available yet. From all apparent indications, the WD_BLACK SN7100X NVMe SSD appears to be an Xbox-branded version of the SN7100 SSD that we reviewed back in March. That's right: you don't need a tiny M.2-2230 or M.2-2242 SSD like you do for the Steam Deck; just like the original ROG Ally X, the new models support an 80mm drive.
