Running 2 separate hardware enabled RAID devices

Posted on 2014-08-02

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?

    There is no reason two separate RAID controllers should have any problems running simultaneously. If both support eSATA I would not worry about using USB3 - it's slower in sustained throughput.

    As Lee noted, you can have multiple RAID devices with no problem ... you can even create multiple RAID arrays on most internal RAID controllers.

    As long as you have enough eSATA connections, there's no problem using eSATA for both of the NAS's.    As long as your eSATA ports are SATA-3, they're marginally faster than a USB v3 port ... if they're only SATA-2, the USB3 port is faster.    But odds are that BOTH interfaces are faster than the sustained transfer rate of the NAS, so it won't really make any difference.
