Seagate's FreeAgent GoFlex: Modular External Storage

Benchmark Results: Read/Write Throughput

The eSATA and USB 3.0 configurations clearly provide the best throughput, and we strongly recommend using one of these interfaces if you’ll be moving large amounts of data on a regular basis. USB 2.0 works for backup and occasional use, but SuperSpeed USB 3.0 is 3x to 5x faster—a huge time-saver in real life.
