Haven't tried btrfs, or zfs.

I build the raid with mdadm, the use lvm on top of the software raid.

I stay away from hardware raid unless it's a really high end raid controller
with
a support contract from the vendor.  With software raid recovery after a
hardware
failure is much more certain.  With hardware raid you may not be able to
recover
unless the new hardware matches the exact model number including version
number,
and firmware version (controller, and all drives).

With software raid recovery from hardware failures is much more straight
forward,
and more likely to succeed.

I have seen a raid controller go berserk and write garbage on all the
drives.
Raid is not a substitute for backups.
