Transfer Time: 10 minutes 30 secs = 630 seconds

12,993,343 KBs / 630 seconds =
20,624 KB per second or
about 20 MB/s (MegaBytes per second)

13,305,183,589 bytes = 106,441,468,712 bits, so transfer averaged about 168,954,712 bits per second
or 169 mbps (megabits per second).

This is at the low end of the "100 to 400 mbps" listed for FireWire, and (at 20 MB/s) about the same as USB FS (USB FullSpeed; typically 20 - 25 MB/s).

* 1 megabit= one million bits; 1 MegaByte= 1,024 KiloBytes.
