BlacX Duet is an interesting option if you are looking for a hard disk drive enclosure where you can add and remove hard drives very quickly without the need of using tools and/or opening boxes and with the computer turned on.

This new version solved the main drawback presented by the previous version: it now comes with an eSATA connection, allowing you hard disk drives to achieve the same performance as if they were installed inside the computer. Plus BlacX Duet comes with two bays for installing drives, not only one. Another advantage is the compatibility with both 3.5” and 2.5” units.
