NitroAV on Thursday announced the release of its eSATA II Professional ExpressCard. It costs $69.95.
The expansion card fits into the ExpressCard/34 socket found on MacBook Pros and some PCs. It connects to external storage peripherals that support the external Serial ATA (eSATA) interface.
The card includes two eSATA ports, one stacked on top of the other. It can communicate with eSATA devices at up to 3.0Gbps (full SATA II data rate).
NitroAV says the card can achieve faster sustained transfer rates than are possible using FireWire 800. eSATA is an increasingly common peripheral interface for digital video, digital audio and RAID systems, where maximum transfer speed is of utmost importance.
