"Akasa has a full range of external hard drive enclosures. The integral line-up includes every connection variant from LAN and USB 2.0 to eSATA. The Akasa integral eSATA combines USB 2.0 and eSATA. You can also use an IDE or SATA drive with the enclosure. This makes the integral eSATA a very versatile enclosure. We use every possible combination and take a look at the performance of both connection types. Its stackable, sleek looks combined with the good performance make this a perfect choice for users who plan to use multiple external enclosures."
