I really have a hard time trusting these kind of devices and would rather stick with a real system using real RAID or ZFS. I had a ReadyNAS a few years ago and liked it, up until the power supply died. Suddenly I couldn't access any documents and needed to order a new power supply and wait for it come. It may be convenient, but the parts aren't easily swappable. I can't pull out the controller and rives and plug it into something else. If it was just a normal system, I have plenty of spare parts laying around or can easily drive to Fry's and get almost any part there. Instead I found how to modify an ATX power supply to work for it, powered it up long enough to copy all my data off, then ditched it.
