Looking for DAS recommendation

I have an air-gapped machine that I need to backup on a weekly basis. Does anyone have a recommendation on a DAS solution? Capacity should be 10-12TB. USB is fine. Ideally it would be black (hate to break the color scheme). JBOD is fine. Trying to get something pre-built if possible. I looked at the PROMISE Pegasus2 R6 but don't have any experience with the brand.

Thanks in advance.
