So I'm trying ide raid instead of scsi for a change. For convenience I want to use a couple of drive trays for easy swapping of failed disks. I see some of these racks specifically marketed as hot swap capable. I can't come up with a difference though. The ones I've seen in the past cut power to the drive when you unlock its sled. Since i'm going to be using raid I won't be worried about data loss. Is there any reason I should pay more for a rack that sells itself as being hotswappable versus just a cheap one?
