A year ago I set up Ubuntu server with 3 ZFS pools on my server, normally I don't make copies of very large files but today I was making a copy of a ~30GB directory and I saw in rsync that the transfer doesn't exceed 3mb/s (cp is also very slow).

What is the best file system that "just works"? I'm thinking of migrating everything to ext4

EDIT: I really like the automatic pool recovery feature in ZFS, has saved me from 1 hard drive failure so far

Make sure you don't have SMR drives, if they are spinning drives. CMR drives are the I ly ones that should be used in a NAS, especially with ZFS. https://vermaden.wordpress.com/2022/05/08/zfs-on-smr-drives/

From the article it looks like zfs is the perfect file system for smr drives as it would try to cache random writes

Possibly, with tuning. Op would just have to be careful about reslivering. In my experience SMR drives really slow down when the CMR buffer is full.

It's an SSD, that's what worries me the most
