Running Windows 7 Pro, I have a NAS (SansDigital) with a built in hardware RAID controller. I would like to add a MediaSonic Pro RAID (which also has a built in hardware RAID controller) as a backup to the SansDigital. Both have eSata connections but the MediaSonic also comes with a USB 3.0 port. Can 2 separate hardware enabled RAID (5) devices work together and be seen in Windows? If so, can I use the eSata on both boxes or should I use the USB 3.0 port on the MediaSonic?
