I think for small amount of disks (around 4) btrfs is a better option. |
20 |
For larger amounts (think 10+) ZFS is a better option. |
21 |
|
22 |
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. |
25 |
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. |
