To answer your question with a question, why do you want RAID? Are you
looking for a system that can reboot even with a failed drive, more
speed, or just security against hardware failure? I run Linux software
RAID-1 on my server and I can power down, pull a ribbon cable off of a
drive and then power up with no problems. Chances are the built-in RAID
will give you redundancy if that's all you need. It may or may not let
you autonomously boot with a failed drive.
Perhaps someone else can chime in as to whether the hardware RAID you
have is any faster than Linux software RAID.
