I was asking myself which which has the higher read/write speeds: A USB2.0 flash drive or a SD card.
Concerning the USB2.0 flash drives, I found that they have a maximal read/write speed of 30MB/s. But what about SD cards? I found that there exist several classes of them, but they only specify the minimal write speed and bus speed. What is the actual read speed of a SD card?
If I had a big program (>16 GB), that I wanted to run from flash drive or SD-card, which one should I choose?
