SMART protocol is defined for ATA interface, and it is translated over USB
interface by most but not all USB-ATA bridges. I have never seen it
implemented for SD cards. Historically, it makes sense: SD card firmware is
just a tiny block management layer, although of course there's no
fundamental reason why it  couldn't be expanded to provide some of the
internal information via SMART---but it has never been done AFAIK.
