What happens if the NAS dies though? What does recovery look like?
Is it possible to recover the data from the drives without Synology’s OS? If so what is that process and how difficult is it to do correctly?
I know that with ZFS, recovery is independent of vendor OS and/or hardware, so if the hardware dies you can just throw the drives into any COTS system with enough ports, but I’m genuinely unsure if that is the case for Synology or not.
If zstd is available, it is a lot more efficient and performant over gzip.
