Asus’s ROG Ally a pretty high-end device for a handheld gaming PC, but it’s not quite as high-end as it could be. It only comes with a 512GB SSD, and if you’ve played any AAA game made within the past few years, you’ll be full aware that many of them, maybe even most, can hit 50GB or more easily. 512GB could easily get eaten up by 10 games.
