I'm getting very different numbers... I may be wrong though?

(7,000,000/8) = 875,000 bytes/s = 0.834 MB/s

0.834 * 60 * 60 * 24 = 72,057 MB/day

(EDIT: Tweaked numbers, had mistyped 0.834 as 0.844 — doesn't affect the point)

Your number looks the same, 72GB/day = 8,859GB over 4 months.

Right, sorry.
