eSATA
eSATA allows for full SATA data transfer rates (3 GB/sec) between a drive and the chipset, approximately six times the data throughput of USB.
eSATA on your computer also supports hot-plugging. Hot-plugging allows for device detection without powering down your computer prior to connecting the
device to your computer. When a device is connected, the operating system automatically recognizes the change. However, the computer must be powered
down before removal and/or replacement.
Installing eSATA Without a Riser
1. Remove the computer cover (see Removing the Computer Cover ).
2. Remove the filler panel for the card slot you are using for the eSATA connector.
