Um, don't? Like other people said, go with eSATA, hopefully hooked up
to a 4-drive or 8-drive enclosure (or even a 10-drive enclosure).
Alternately, go with an external SAS storage rack that supports both SAS
/ SATA drives. A SAS card for PCIe is fairly inexpensive ($200?) and
the external enclosures are probably going to be (but not certainly)
better made then inexpensive SATA enclosures.
The big problem with USB is that it only supports about 25MB/s per port,
which means that it's going to be very very slow. Modern hard drives
can push 50-80MB/s easily.
