My mom's backup hd for her iPhoto library failed, I'm under the impression that a RAID hd should be the best way to go to prevent this from happening in the future. I need a RAID that has 2 hd's that simply mirror each other. I think 2 x 2TB drives should be more than plenty for her. I searched but all the results seemed to cater to much more professional inquiries. I'm just looking for something simple, easy, reliable, and not exhorbitant in pricing. Any suggestions? Better alternative? Am I in the wrong sub forum? Thanks everyone.
