I just got a DP55SB and I've got most everything running great. I had the ESATA backplane connected set up with an extra SATA drive for my first external drive (in a nice enclosure). It works fine but doesn't hot-swap which is a major annoyance.
Support is saying I need to set the Marvell to RAID but then that means RAID drivers and complications. Can this setup hot-swap and is that actually how it works? Never bothered with RAID.
