I did not do benchmarks. It's just my personal experience that I've yet
to see an USB-attached disk which feels fast. Remember: Disks do not
speak USB, they are adressed via IDE or SATA. So, if you use USB, you
get an additional translation layer.

Apart from that it looks like USB is not optimized for fast transfer and
low latency. SATA et al are designed for adressing hard disks, they
don't care about input devices etc. So there is less overhead.
