2-port eSATA ExpressCard/34 Host Adapter
T-EC2S
This 2-port eSATA ExpressCard/34 Host Adapter supports a single-lane 2.5Gb per second PCI Express bus, and provides a SATA II transfer rate up to 3.0 Gb per second. It bridges a connection between 2-port eSATA ExpressCard/34 Host adapter devices and the host computer plus delivers dramatic speed increase over standard USB 2.0 and FireWire. Point to point SATA connection eliminates the need of conversion from the eSATA Express Card signal to a second interface; it unlocks the full potential of the SATA II data transfer speed when it is in use. For example, it is compatible with eSATA HDD enclosures.
The identical protocol and signaling of the 2-port eSATA ExpressCard/34 Host Adapter allows native SATA devices to be used with external enclosures with minimal modification. Most external HDD enclosures, with FireWire or USB interfaces, support either PATA or SATA drives; and provide a "bridge" between the drive's interface and the enclosure's external port. This bridging may incur some inefficiency. During real use, some of the single HDD can transfer up to 120 MB/s. This is twice as much as the maximum USB 2.0 or FireWire 400 (IEEE 1394s) transfer rates and over the maximum FireWire 800 transfer rate.
Low-level drive features such as S.M.A.R.T. may not be operated through USB or FireWire bridging, but the 2-port eSATA ExpressCard/34 Host Adapter solves this issue.
