I'm getting a little leary of the 1.5TB WD HDD that has all Kim's photos going out one of these days. I have an external drive backup right now, but thinking about going to a more elegant solution of two HDDS in RAID. The system files will remain on the 128GB SSD as that seems to be plenty for what we do.

Any suggestions on 3 or 4TB size drives to look at? I'll get 7200rpm drives at least, but they have all kinds of marketing crap and stuff now that I don’t really know whose are the best. These will mostly store photos and such...
