#2 Full write/read of a disk

[Guy Kisel]

Benchmark a disk from the outer diameter to the inner diameter.

Proposed methodology:
1. Generate a 1 GiB file on the source.
2. Write the 1 GiB file to the target.
3. Read the file from the target to the source, but do not delete from the target. Record the resulting speeds.
4. Repeat steps 2 and 3 until the disk is full, then plot the results.
