What you say is true, however on my Sheevaplug sometimes I see what
look to be excessively high I/OWait times in 'top'. I don't know
enough about internal kernel workings to really speculate why this
happens, but it does seem to be more complex than just Mbps used vs.
Mbps available.

In my case, it could just be a braindead chipset in the cheap crappy
USB->SATA enclosure I use for my hard drive.
