Drobo 5N or 5N2 convert to TrueNas or Unraid

[Enquiries]

Hi there, Like your channel BTW.
This might be an unusual question as I cant see it referenced on your site....but ....

1. Can TrueNas or Unraid be installed and run on a Drobo 5N or Drobo 5N2?
2. If so, which would be better? I.e. Would truenas provide a worthwhile performance improvement over the current drobo software or would the drobo hardware spec be a bit limiting and
therefore Unraid would be a better option?

This would (most likely) be used for a raided backup only of another NAS and likely just for incremental back ups.

Thanks

Deano
