I also back up to two different large ext HD's. My tunes library at the moment is a bit over 200 GB, not including some Amazon and HDTracks files. Pictures and Word files all together, I have a bit more than 500 GB. The drives are WD 2.0 TB. I use usb 3.0, and it is dramatically faster than usb 2. Would you consider putting a 3.0 board in your PC?
