I built my own. All drives are used for storage of data. I use a decommissioned server power supply. 2 PCIe expansion cards for connectivity. My case is a large plastic container with lid from a dollar store. Regardless of its content, each drive is encrypted, and each has its own mirror at a remote site. Every Drive regardless of location, has its own on-off switch. Cheap, somewhat primitive but secure.
