OWC has brought its experience in making SSD upgrades for Macs to a new external storage device called Envoy Pro Ex ($320-$600). Available in either 240GB or 480GB capacities, this is the latest external drive to borrow heavily from Apple’s unibody aluminum design language. Although expensive, the small body, speeds, and overall reliability of SSD technology make it an interesting option.

Envoy Pro Ex is palmable, at a little over two inches long, less than half an inch tall, and four and a half inches long. It connects to your Mac using USB 3.0, which provides transfer speeds up to 500MB/s, along with the necessary power to keep the drive running. The anodized aluminum body is a perfect match for your favorite Mac.
