7200 rpm is the highest spindle speed for 2TB drives--5400 is most
common. None of them are going to do much over 200 random seeks/second,
if that. That's 400 tops for two drives.
Using any modern Intel/AMD ~2 GHz CPU, you think he's CPU bound?
Apparently this "rm -rf" type operation is much more complex than I
previously believed.
