I have been using ZFS almost two years on servers and it is easy to deal
with drive replacements. I have even switched my desktops and laptops to
ubuntu 20.04 ZFS for the snapshots.
Issues are learning ZFS and Raids they are not real hard to learn but then
replacing drives as they fail = Time vs money saved Do you have the Time to
learn and spend swapping?
I have a old synology NAS you or someone else can have that can be updated
to debian and ZFS 5 bay hot swap, great way to start out
