file-system choices for unraid

[ArveVM]

Currrently multiple options for file-systems in unraid: xfs, btrfs, zfs

It is my understanding that

• zfs will enable mulitple drives in one pool, snapshots and zfs-move/backup functionality, but comes with some overhead-cost.
• btrfs will enable pools of multiple drives
• xfs is just better on the stability side of things (source: https://unraid-guides.com/2020/12/09/what-is-the-best-filesystem-for-unraid/)

So that leads to theese use cases for me: XFS for Array-drives,, want solidity, and not accepting overhead for zfs, and no need for zfs-snapshots on array-data XFS for single pool-devices ZFS for single/mulitiple-drive-pools where I want zfs-functions (snapshot/move etc) BTRFS for mulitiple-drive-pools where you don't want zfs-functions (snapshot/move etc)

yeah,,, after some more googleling and forum-scouting,, I believe since i operate with single disks as cashe/pool-ssd/nvme they can use xfs Only if I want to create a pool of my 4tb-drives besides the array-- then I can consider XFS (but will then require more RAM)
