I'm just really looking for a RAID card that will do RAID 1, with four drive capacity, i.e.,
a master drive with the OS and applications installed and mirrored, and a slave drive for data and
photos, graphic design, video, etc also mirrored. What would battery built into a RAID card
do for me?

So you reccomend Areca, good thanks I'll check them out too. How are they for RAID 1?

Will check them out too Thanks Karanbir
