Does not matter on what distro. What do you want to do?

A RAID controller generally has more features / error messages than just 
a plain controller. Things  like:
- are all the disks still functioning?
- if one is down, which one is that, and which of my RAID volumes is now 
running in degraded mode?
- a possiblity to start resync after you have replaced broken hardware
- Often the controller can do sanity checks on the RAID volumes, you 
want to shedule those at times that suit you

My experience is with SCSI RAID, so no comments.
