[ale] A little math

[Sean McNealy]

Testing to a file on my machine (no raid going on)
512000000 bytes (512 MB) copied, 81.1661 s, 6.3 MB/s

extrapolation: 1TB @ 6.3 MB/s is 44 hours.  Wow, that is a long time.

I forget the relevant specs for this machine, but for comparison
copying that same 512MB file was:
512000000 bytes (512 MB) copied, 7.091 s, 72.2 MB/s

And... now I'm out of entropy!
