Answer
These drivers support snapshots but have slower random writes compared to overlay2.
Quick Answer
Btrfs and ZFS offer advanced features (snapshots, deduplication, checksumming) but are more complex than OverlayFS. They can have worse write performance in some workloads due to copy-on-write overhead at the filesystem level, especially with many small random writes. OverlayFS is faster and simpler for most container workloads.
