What happens with a Hardware Failure

[KevinE]

I am halfway through my 30 day trial and loving unraid. My use case is to run a nas box on my sailboat - which means my hardware is exposed to salt air - so a hardware failure is not an if, it's a when. Just curious how this will work if I am running a 3 or 4 disk spanned array (with 1 parity drive)  and end up having to introduce new hardware which may or may not be the same as what I am currently running (QNAP)?

Many of us have changed hardware over the years. I have replaced everything on my main server at least twice, never lost any data, all still running on the same flash drive and license.
