For RAID1, I am not sure.
But for RAID 5, You should always use hardware RAID.
If you use software RAID and your CPU spikes for too long, you can corrupt your
disks. I have seen this several times.

Please report this to the linux-raid mailling list,
run as a web interface or command line so the whole monitoring argument
is mute IMHO.

While hardware RAID tend to be more reliable, it is not always
possible to properly monitor hardware raid in a linux system, unless
you write your own code.
