USB2 transfer rates

[PinataUT]

I bought an ICY DOCK enclosure and am doing a data transfer to it via USB 2. Transfer speeds are 21 Mb/sec which seems slow to me.

The disc was quick formatted (brand new WD 750 from 'egg).

Is this slow? I expected it to be quite a bit faster.

Suggestions?

Theoretical is 60MB/s. I typically get 30MB/s out of my WD2000JB enclosed in a USB2.0 Vantec. If you want something faster, get eSATA.
