These chips were low performance and limited number of write cycles. Even with a great controller (which would be expensive) you're looking at slow transfer rates. If it reaches USB 2 capabilities, you're lucky. This guy kinda was.
- aexaey 9y agoSD cards and eMMC chips[0] do have controller inside. Usually not a great one (tens to hundred-ish MB/s), but that's good enough - overwhelming majority of smartphones/tablets use eMMC for internal storage. UFS/eUFS cards keep (sort of) same form-factor [1] but bring significant speed boost. [2] [0] Technically, it is incorrect to say "eMMC chip", as there are typically two (or more) silicon chips inside the same plastic BGA package. One of them is controller.
