OWC Mercury On-The-Go FireWire 800 / USB 2.0 Portable Hard Drive Kit @ TestFreaks
 

Instead of placing your old 2.5" hard drive into a slow USB 2.0 enclosure, why not try something faster. OWC offers the Mercury On-The-Go FireWire 800 / USB 2.0 Portable Kit which allows the user to take advantage of Firewire 800 speeds. Plus the clear acrylic enclosure lets you see exactly which drive is housed within the enclosure.
