Software RAID is always, in my experience, more stable than on-board "RAID" especially if you only have one OS.
The only issue I have ever had with software RAID (Linux MD and LVM base RAID), has been the boot drive.
Without a piece of hardware to present a single LUN to the BIOS, or a BIOS that understands the boot RAID set, booting from a degraded RAID, when the failed device is the primary drive always requires manual BIOS intervention.
So, if I have the spare CPU cycles/IO bandwidth available, I do like using software RAID for the data/non-boot volumes.
When it comes to the boot volume, other than with AIX, I have not found a more reliable RAID other than hardware based.
