at present we can only see drive info for ATA-compliant devices such as harddisks and SSD - but what about older USB-sticks, SDXC memory cards and connected smartphones, tablets...?
I would suggest s.m.a.r.t. info like power cycles, terrabyte written, info about NAND life span (if manufacturer publishes guaranteed TBW) and info about NAND type and nm size.
I think there's a market for that - there are so many people that don't know about remaining life of there flash media.
Not all USB-sticks seem to be ATA-compliant and offer s.m.a.r.t. such as OCZ Rally2 (announced in 2006) -
