So, realizing that if I do get a nMP tomorrow or February, I'm going to need some external storage. What I realized quickly is there is a dearth of standard external storage that is available with TB now. (There are a lot more raids, docked systems, and whatnot, but not a lot in the way of standard external HD available.) I was going to get a G-Tech, but that doesn't appear to be an option for the next few months. So.. what to get that's reliable? Or should I just get a USB 3 unit? (I'll be doing PS and LR work on the files that will be stored on this drive, with backup to an existing G-Tech docked drive).
