I think for small amount of disks (around 4) btrfs is a better option. For larger amounts (think 10+) ZFS is a better option. This is based on the design ideas and due to the lack of a robust raid5+ implementation in btrfs. ZFS requires more memory to perform well, compared to other filesystems. I believe btrfs doesn't have this requirement. I don't have any systems with this yet, but am planning on implementing btrfs on desktops and seevers with small amount of disks. For the servers with higher disk-counts, I am planning on implementing ZFS. -- Joost -- Sent from my Android device with K-9 Mail. Please excuse my brevity.
