I'm looking for some suggestions on a solid plan for backing up and storing design files. Currently I have 3 external drives one WD Passport Studio 500GB (FW 400, 800 and USB 2.0), one G-Tech 250GB (FW 400, 800 and USB 2.0), one self-built 500GB (USB 2.0) and a WD MyBook 2TB (FW 400, 800 and USB 2.0) Each has on overlapping of files so that between the 3 and my laptop I don't lose much if anything should one die. I've checked out Drobo FS and the Synology DS411slim and am stuck on the fence. I probably think I am a little more tech savvy than I might actually be so a RAID system I have to setup is a bit beyond me. I'd like it to me a NAS so that the other computers in the house can pull from it. Thoughts or suggestions? Thanks!
