Raid 5 is Ready! (Score 1)

I personally have a Raid 5 setup. Never had a failure nor any real problems once I made sure the bios/driver versions matched. When building a system for home I think it is important to consider the available equipment. Promise makes a line of cost effective cards in their SX series. I would look at a 4 channel card that will handle 4 drives. The 6 channel cards are so long that they may not fit in your case! I added 4 x 120Gb drives and created 360Gb of usable space. The card was only $150 and drives are so cheap these days. For fun I have removed a drive and watched it be rebuilt when I turned it back on. At that price point I don't think you can go wrong.
