I know it has something to do with arrays, and mulitiple HD connected together - but could you explain to a nontechie whether this makes sense for personal storage? Like most people, I'm accumulating lots of digital images and music and clones that fill up drives, and I've got 3 externals already.
I've read about Drobo, which seems to offer an alternative that some say is an improvement over RAID. Any thoughts? Thanks.
