This 2-port Flush Mount ExpressCard 54mm eSATA Controller Adapter Card uses a unique slim form factor design that allows it to sit fully in a standard laptop ExpressCard/54 slot without sticking out. When installed, the ports sit flush with the sides of the laptop, creating a seamless add-on that can be left installed at all times, without fear that it or the card slot will be damaged due to snagging or impact.
The eSATA ExpressCard adapter features two independent eSATA ports, and is compatible with the latest high capacity SATA drives (SATA, SATA 3Gb/s) with support for data transfer speeds up to 3 Gbps. With support for Port Multiplier technology and hot-swap installation, the eSATA ExpressCard allows compatible multi-drive enclosures to be connected over a single eSATA cable, and devices can be connected and disconnected without having to reboot the system.
