That happened to me.

My QNAP TS509 died within the first few months of use. I sent it back for replacement and was able to simply stick the drives from the failed model into the new one and they worked as though nothing had changed.

I now keep a spare TS509 box available for such issues.

Can I put the Disks inside another Manufacturer's NAS
OR
Should I buy another NAS Enclosure as a Backup?

That's probably less likely to work as it's likely there are proprietary settings on the drives...
