   The problem with "true hardware RAID" is that if anything goes wrong with 
the RAID card, it's necessary to purchase an exact replacement to get the 
RAID working again, and in between the RAID is a paperweight.  If the card 
purchased is no longer available, well -- oops.  Also, many of the 
so-called "hardware" RAID cards are actually doing software RAID in the 
driver, because it cheapens hardware manufacture costs.

   Software RAID doesn't require proprietary drivers, and many distros have 
options to set up RAID right from the install menu.  It can be a bit more 
tricky if wanting to do something slightly out of the ordinary [root RAID, 
setting up the boot loader to boot from a mirror drive, etc].  There are 
HOWTO documents available for setting it up.
