Industry's most trusted hard drive docking station is now twice as convenient. BlacX Duet now offers two slots to turn any Serial ATA hard drives into external USB 2.0 or eSATA storage device in minutes. Moving large chunks of videos, musics or data files between hard drives will now happen in blazing speed (up to 3.0 Gbps for eSATA or 480Mbps for USB 2.0) instead of the slow network cable. The dock supports all 2.5 inch or 3.5 inch SATA hard disk drives up to 2 TB. Installation requires no screws or tools whatsoever. Simply pop your hard drive into the dock, plug it into your computer and you are set! Hot-swap support means you can use multiple hard drives with your computer without having to reboot. The dock also maximizes heat dissipation and exhaust to protect your device from damage and extend its life. Compatibility with both PCs and Macs makes the BlacX Duet adapt to multi platform environments.
