    Damn, literally just bought a card yesterday and this would have been useful lol. Saw a review online the 1 Tb san disk pro extreme was good and seems to work just fine so lucky enough I guess.

      SanDisk Extreme Pro is one of the best, in my opinion, they excel in IOPS for small random read and write which is especially important when using it in a computer like Steam Deck or Raspberry Pi. A lot of other SD cards are optimized for cameras where it is writing a lot of sequential data, but are slower in small reads and writes.

        Thanks for the insight! Glad to know it was a good purchase. Although, got burned hard on a phony from Amazon. Thought it was my deck, but SD card I picked up from MicroCenter works like a charm. Will likely never get electronic hardware from Amazon again.

      Because there are orthogonal performance properties and making them all get “better” with a higher “performance” number would be very expensive. Someone taking photos wants high capacity. Someone taking 8K video wants high write bandwidth. Someone playing games or as phone app offload storage wants high IOPS.

      It’s why yo can buy a 1TB low-IOPS card for $40, or you can buy a 256GB high-IOPS card for $40. But if you want 1TB with high-iops, you’re going to pay about $200.

    Can someone explain like I’m 5, how its possible to fit a TB of storage on something so small, and why if its possible to do that are they not used for everything?
