The EC2 is an eSATA card capable of delivering higher bandwidth than FireWire can, up to 125MB/s on each of it's eSATA connections. It's a 3Gbps/port SATA II card which uses a PCIe slot in your computer.
Using eSATA, copy speeds will increase significantly when moving large amounts of data from one drive to another. Typically, a GT 050Q can transfer around 70MB/s when connected via FireWire 800. If connected to a EC2 card, speeds of over 110MB/s are easily attainable using the same drive.
The EC2-2 ships with a 1-meter eSATA cable.
The EC2 supports all Serial ATA II features, including 3.0 Gbps SATA II transfer speeds, Native Command Queuing, port multipliers with FIS-based switching, programmable output signal swing strengths for longer external cables or extended backplanes, hot plugging, enclosure management and ATAPI device support.
