I don't have experience with setting up RAIDs though I've read a lot and don't think it would be too difficult. The Drobo doesn't do eSATA and I really want the fastest possible so OWC Mercury Elite beats it there. Still I've fallen victim to the Drobo gimmick where it seems really easy, does it all for you, but most importantly you can use any size drive and the Drobo does the dirty work. I'm not even sure what this "dirty" work would involve since I always thought when building an array you needed to have drives that are identical in model/make and size. Am I wrong? Can a cheaper OWC Mercury Elite like this be as user friendly as the Drobo? Are there other recommendations? Barefeats recently reviewed the OWC Mercury Elite here but it doesn't compare it to other setups. In fact it say's in the article it won't provide blazing speeds without dedicated eSATA channels which isn't exactly a positive review. Still it would be faster than a Drobo. Am I missing any other options for the same price or less?
