Hey guys! Does anyone know of any dual hard drive enclosures that accepts portable hard drives with a USB port built in like the Western Digital Passport? Essentially I'm looking for a dock that I could pop two of those type of drives into, mirror them both with my iTunes (music) and iPhoto (photos) folders, then be able to grab one of the two when I travel to keep it with me in case my house burns down or gets robbed while I'm gone -- so one of the copies stays at home and the other goes with me just to be safe. Not interested in regular dual hard drive enclosures for SATA drives because you can't plug the removable drives right into a computer with a USB cable and I want to be able to do that with my MacBook (like with any external HDD like the WD Passport). Know of any solutions? Thanks in advance!
