Agree with CCC. By the way OWC makes this great little Voyager Q which you just stick a 2.5 or even 3.5 HDD into the top of and immediately clone, backup, copy, move stuff into. Mine has USB2x1, ESATAx1,FW400x1 and FW800x2. All cables are also included. It costs $90 in that config, but they offer a USB3 model for like $40 if I remember correctly. Either way a small price to pay for losing valuable and/or irreplaceable data.
I plan to mainly use it to clone and/or backup entire HHD's and then take them off site to a bank vault in case of hurricane(s). Have to think about that being in FL.
