Hardware RAID - Implements RAID through a dedicated card that contains a
special processor and memeory(usually on some sort of add-in card [RAID
controller card]) on it to take care of the RAID commands/processes.  Some
motherboards have them built on now. = FASTER

Software RAID - Implements RAID by using a software program or (as linux is
concerned) via the kernel.  This method uses your main CPU to process its
commands thus taking away processing cycles for other things. = SLOWER

That is how I understand it -- More on RAID can be found here --

Can anyone tell me the difference between hardware and software raid. I
know that the MSI motherboards come with raid controller on the
motherboard. Is that considered software or hardware raid? What is the
easiest way to do raid with 7.1 redhat?
