Do you feel comfortable with reliability of btrfs?

When I do a Google search, I want to see confirmed cases of fs lockups / data loss from fs bugs to be multiple years in the past. btrfs isn't there yet.

I like btrfs's ability to e.g. switch raid levels without offlining the array. I think it's promising. But I wouldn't trust my data to it tomorrow.

Raid 60 is not really that good. the rebuild time of a raid 6 slice of 12 disks is 36 hours. (sas 3tb disks)

Raid 10 is more expensive on space, but is the best compromise of traditional raid.

LSI have some fancy magic virtual disk chunking mechanism to make rebuidling large raid 6 luns much quicker (4-8 hours)

For a home NAS intended to stream video, my experience is 'no, don't'. I ran btrfs on my home NAS (on mdadm RAID1), and playing video from it was awful - pausing every few minutes. I thought it was just my misconfiguration of samba, but a rebuild using xfs fixed it, and a friend having the same problems on a btrfs (no raid) home media server now make me gun-shy. I don't need the benefits btrfs has on my box, so I'll stick with xfs.

I am very much not a filesystem expert, but my experience is that for me, btrfs is no benefits and significant problems.

They are running BSD. I don't think BtrFS is an option and ZFS can do pretty much every trick BtrFS can.

The data corruption on the first machine seems like a hardware problem.

ZFS has inbuild raiding and much much friendlier tools.

The BTRFS tools are like MDAM and lilo had a child.

Because BRTFS isn't even feature stable yet.

... or supported on FreeBSD, which is what the server runs.
