Preliminary USB 2.0 Benchmarks

Write speed to the external USB 2.0 drive seems to be around 1.5 to 1.75 Mb/sec (5.27 to 6.15 Gb per hour), which means roughly 24 hours to fill the 75Gb drive that I have in there. That's a bit slow (should be up around 3.0Mb/sec).

The RAID1 set of 5400rpm drives has a bandwidth of around 6Mb/sec (copying 6Gb of data from one part of the disk to the other gave me 3Mb/sec read, 3Mb/sec write).

I'm going to go dust-off my little performance app that I wrote and see how those numbers compare to earlier baselines.
