In conclusion, this is one of the fastest external drive enclosures using conventional HDDs I have ever used. It is very quiet and looks good next to my MacPro. It also comes in a dark metal enclosure. You want one of these! Read More...

The AKiTiO SK-3501 Super-S3 is an external case for 3.5" hard drives. The Super-S3 has four connectors on the back: USB 3.0, eSATA, and two FireWire 800 ports. Read More...

This baby is a real beast, built to take some everyday abuse. The great plus here is that being an enclosure, you have unlimited options on what storage media you would like to use. The real feature that I was excited to try, was the USB 3.0 interface and the potential transfer speeds of 5Gbps. I was interested in seeing just how much faster USB 3.0 would stack up against FireWire 800.
