    Works great for my steamdeck, plenty of space. Honestly I'd recommend to go at least this big for a steamdeck because games are so huge nowadays. I actually upgraded from the 256GB which also worked well, but updating BG3 was becoming a pain LOL

    Works as advertised. Using it in a Raspberry Pi and have had no problems with it. Coming with a USB adapter is very useful and provides more value compared to other SD cards, especially if you are needing to read or write to it a lot.
