If the nas dies but the drives are fine, I just grab a new (synology) nas and stick the drives in. The OS will see that it's in a new model, and start the process of migration (anything that needs changing, enabling, or disabling vs the prior unit, hardware and software capabilities, etc). It's super easy; I've done it myself when I upgraded units a few years ago. If the drives die I have local and remote backups.
I believe it is possible to extract data with a standard Linux system, though it's been several years since I looked into it. I don't run raid on my usual machines (well, I have a wd black pcie card with 2x nvme drives running in raid0 on a hw raid chip onboard, but the system is oblivious and thus so am I), so I'd have to do research again if such a situation occurred. I'm not planning on moving away from syno so currently the hypothetical would end up just buying a new unit and being done with it.
