While we're on filesystems, what would be the better choice for a home NAS array with, say, 10-20 individual drives and, say, ~2-300 TB raw storage: ZFS or btrfs? Let's assume that all drives in the array are connected via a common SAS or SATA 3 backplane and that the array is on a local network with at least 1Gbps speed.
Is there any other fs that would even merit consideration at this point?
How does the inclusion of SSDs as cache drives for the array modify this?
ZFS for sure. RAID on btrfs is still not quite stable and commercial deployments such as Synology use a different software raid layer instead of the built in support.
Ps just considering reliability here. In terms of performance I don't know.
Performance is better on ZFS too, especially for bittorrent and VM images. Just remember to set recordsize appropriately (typically 1M for large file storage).

Does any of this change if we specify 10Gbps LAN?
