BTRFS settings for media storage

[Richard Shaw]

I've been running MythTV for about 10 years now and I've finally outgrown
my media storage, currently a single 4TB disk drive. I have purchased 3
additional drives of the same model and plan to put them into a BTRFS RAID1
array.

Setting nodatacow on the media directories is a no-brainer, but what other
optimizations can I do?

Thanks,
Richard
