About Powered eSATA
External SATA (or "eSATA") ports can transfer data at very high data rates (up to 3.0 GB/s). However, the original eSATA specification does not provide a power connection through the standard eSATA connector. This is inconvenient for portable external hard drive applications, because it means use of the portable drive requires both a data cable and a separate power cable or AC power adapter to power the drive. Recently many laptop manufacturers have included a combination USB/eSATA connector that can be used in conjunction with a special Powered eSATA Cable to provide a single-cable solution for portable Powered eSATA hard drives, such as your new Verbatim drive.
