There's gotta be something like 1,000 1TB MicroSD cards per 22TB hard drive.

if you go purely by cubic volume:
3.5" Drives are 146mm x 101.6mm x 25.4mm (full height) = 376,773.44 mm³
2.5" Drives are 100mm x 69.85mm x 19mm (full height) = 132,620 mm³
uSD cards are 15mm x 11mm x 1 mm = 165 mm³
2,283 1TB uSD cards will fit in the same cubic area as a 3.5" drive.
803 uSD cards will fit in the same cubic area as a 2.5" drive.
The aforementioned 22TB drive was a 3.5" drive so therefore that
proverbial station wagon can hold 2,283 times more storage and therefor
bandwidth by carrying uSD cards instead of 22TB hard disk drives.
Please note: This calculation does not take into account that due to
the smaller volume of the uSD card more of them might be able to fit
into the station wagon than the equivalent number of hard drives.
I will leave the determination of exactly how many 3.5" hard drives can
fit in that station wagon vs uSD cards.

Make that 22 TB hard drive and the storage
density goes way up.
Well, certainly more than tapes.
A 22TB hard drive is physically smaller than 22 1TB Micro-SD cards?
