Hey, so my mac pro is getting CRU'd and it's lead me to have to address my RAID issue a long time before I would have liked to. Currently, I have a pro with a 4 drive Caldigit raid 5 (yes, i know, caldigit controllers aren't fantastic, but it was $300 at the time, and has lasted me very well) So here's the pickle I'm in, I really don't like the idea of running a bunch of backwards drives with free-floating cables inside them, but on the other hand going exernal or to any other solution is expensive. I know the apple raid card isn't a fantastic performer, but honestly i'm more interested in data redundancy and efficiency than raw MBPS rates, and it seems nice to not have to have everything hanging outside the computer or inside, seeing as i'll be moving it back and forth between college and home, and carrying one around is a lot better than two, seeing as most external solutions are about the size of my mac pro! So, here's what it comes down to, spending $1k to get a mac pro raid card (apple) and new drives (i have nowhere near enough space to transfer all 3TB off onto other drives for the transition) and gaining nothing, or really hunkering down and looking a quality raid system so i'm not just spending money to maintain my status quo. I'm looking for price conscious solutions, but also solutions that allow me the ability to grow. noise is an issue since this will be a dorm unit... Any help would be appreciated, and thank you nanofrog for help previously.
