Okay, I've gone long enough with my current backup strategy (crossed fingers, prayers and not looking at my 3 500GB externals too long in hopes they won't get "ootsy") and need something... reliable. Currently, I have less than 1 TB of media, so I was thinking a RAID 5 would be perfect for the three externals, but Apple, as is its nature, has yet to make its software RAID 5 available. In addition to the three HDDs dedicated to media, I have 1 500GB external dedicated to Time Machine backups for my main iMac, which is fine, but none of my external media is being backed up. Drobo looked good (I assume it's little more than a RAID 5?) but I was convinced to steer clear of it by a clown... er... genius at the local store. So, here's what I have at my disposal: 3 500GB externals, plus the one 500 GB HDD used for Time Machine BU of my internal HDD. I am willing to buy a reasonably solution. Ideas?
