My colleague and I are writing an endurance test for SD cards (running read/write/erase block cycles). We're considering using an Raspberry Pi 3 to run the tests on.
The issue is we will be using full sized SD cards, so a SD to USB adapter will have to be used. We need to get to the driver level so we can issue commands to the SD card. However, we are concerned the adapter will cause the SD card to appear as a USB device and we will not be able to issue commands.
Will the SD card appear as a USB device? Is there a way to prevent this?
Thanks for any help!
