I have 4 4TB drives in a BTRFS RAID 1 array for all my media. I know RAID 5 is a bit touchy so I have put that off until I start to run out of space. The cool thing is I can convert on the fly! I have installed btrfsmaintenancetools or whatever the package name is and am running scrubs and balances regularly. Thanks, Richard
