My Book Premium ES Edition drives are nearly identical to their Premium Edition counterparts, the only difference being that the ES line features a single eSATA connection instead of the dual FireWire 400 ports present on the Premium Edition, allowing computers with available eSATA ports to transfer data at speeds of up to 3 Gbit/s. This edition is available in 320 GB and 500 GB capacities.
