btrfs unsafe news
With the recent news that btrfs is unsafe in raid 5/6 mode how does this effect Readynas?

It shouldn't effect the ReadyNAS at all - it doesn't use the built-in RAID code in btrfs. Instead it uses the more conservative approach: mdadm creates a virtual disk with RAID, and normal btrfs runs on top of that.

We've been using mdadm raid since 2008 (when we released the ReadyNAS Pro running RAIDiator 4.2.x). mdadm is very mature.
The combination of mdadm raid + BTRFS is better than mdadm + lvm + ext4
