Trans International today announced the availability of The Pro Sled, a Mac Pro hard disk drive sled that gives users the capability of unlimited swappable drives for their Mac Pro. Drives can be assigned and labeled for different clients, projects or backup. In a high volume, professional setting it is easier to avoid misplaced data and over written files when each client or project is assigned their own hard drive. Once mounted on the Pro Sled they can swapped, stored or taken with you — they will plug directly into the Mac Pro main logic board. No power or data cables are required. Pricing starts at US$29.
