IMO that's a bit slow, but the time might depend to a large degree on how "full" the HD is (if it is a "safe" defrag). Therefore better test cases are 8, 20, 40 GB HDs with at least 1-2 GB free space.

For example, on a modern PC with 1 GB memory, the "min" time for a full and safe defrag of 20 GB, transfer speed 50 MB/s:

read 20 GB * 2: 400s * 2: 800s +write 20 GB * 2: 400s * 2: 800s -------------------------------- 1600s = 27 min

MS-DOS forever!
