They don't have nearly enough power for that, unless the spindles
are only spun up on demand (feasible by structuring records
over time). A rack is about a PByte, so 10^3 racks an
Exabyte. I doubt they have more than 10^4. Assuming 10 kW/rack,
and 10^4 racks, that's 100 MW -- the whole Utah facility
has only 65 MW. 10^3 racks at 10 MW total appears more realistic.
Very large scale HDD purchases should also be traceable by
going to manufacturers.
