Software vs Hardware RAID

[rusty-5uWQAetEYB7jY0qkv+UzOQ at public.gmane.org (Rusty Shackleford)]

That is great,  I was not aware that there are 2 types of hardware raid.  I
mainly use HP Proliant servers and they have an onboard raid controller and
it allows me to do hotswaps.  Also Software raid, is that more suseptable to
being corupted since it lives on the disks instead of a separate entity?
