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?
Does any of this change if we specify 10Gbps LAN?
- wkat4242 3y agoZFS 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.
- tiberious726 3y agoRaid 1 and 0 are perfectly stable on btrfs and have been for a decade. I don't think anyine ever fixed raid 5 or 6 on it tho...
