Sabrent Rocket M.2 SSD If you need to expand the internal storage of your Steam Deck or Asus ROG Ally, the Sabrent Rocket M.2 SSD is likely your fastest yet most affordable option.

Install your new SSD At this point, you can seat your shiny new SSD in the now-vacant socket. Match the SSD’s pins with the socket, and then gently insert it without much pressure.

Modders can install full fat 2280 size M.2 SSD inside the ROG Ally by modifying some parts of the Ally's clamshell.
