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.
