I have been successfully using an Onnto DataTale quad interface, and now I have bought the USB3 version.
These can be had for a very good price, but not from many places. There's also a more expensive TB version, but still very competitive.
I chose them because they support 1+0, can be flexibly configured as multiple volumes, and can be managed by software, and a reconfiguration password set (I avoid RAID enclosures that are only managed by buttons).
I think the speed is OK.
What you will not be able to do is grow a volume after it has been created. For this you need something a lot more expensive, like Areca.
