    What is eSATA?
    The Serial Advanced Technology Attachment (SATA) computer bus has the primary function of transferring data (directly or otherwise) between the motherboard and mass storage devices (such as hard disk drives and optical drives). 'eSATA' standardized provides a variant of SATA meant for external connectivity.

    What is an ExpressCard?
    ExpressCard is a hardware standard replacing PC cards (also known as PCMCIA cards); it is a new technology that slots into a computer system to allow the addition of hardware capabilities. There are two types of the ExpressCard slots: ExpressCard slot/34 (34mm) and ExpressCard slot/54 (54mm). ExpressCard technology gives users the 'sealed box' computing benefits in a PC card form. Previously, to add hardware to a computer, it was necessary to open up the computer with a screwdriver to add the new card. With ExpressCard, you simply slot in the card to an existing expansion slot. This makes it easier to adapt to and helps to keep cost down. The ExpressCard has a maximum throughput of 2.0 Gbit/s through PCI Express and 480 Mbit/s through USB 2.0 dedicated for each slot, versus CardBus's shared 1.06 Gbps bandwidth.

    Please Note: Maximum cable length for connection with the Dual eSATA II ExpressCard adapter is two meters.

    plugged in- worked....

    It works as intended, but I had a lot of problems installing it because the drivers aren't on a full size disc. The small disc that came with it doesn't play well with modern slot drives.
