what's a good transfer rate for usb 2.0 external hdd?

[jcmuse]

Just curious what a good transfer rate when transferring from the external drive -> internal drive via USB 2.0 connection.
I was getting 22.5 MB/s according to Vista when transferring from my external 5400rpm laptop hdd to my internal 7200rpm laptop hdd. Is that a good rate?

it was a pretty decent rate. you'd get ~32 under optimal conditions.
