Would still like to know a bit more about Areca, since I have no experience with them and only heard about their products recently. As an alternative, I was considering the cheap(er) option. The motherboard (GA-P35-DQ6) comes with 6 SATA II ports connected to ICH9R. I have a feeling that using RAID 5 with this option would be rather slow, that's why I'm looking into a dedicated hardware controller. However, RAID 10 is a fairly simple implementation. I can't use RAID 0 because I need redundancy, and RAID 1 is too slow. RAID 10 obviously requires more drives, but for the $300 that I would have spent on the controller, maybe instead it's worth to simply buy an additional drive or two and use the built-in controller. Any thoughts on this? I could probably get 4 320GB Seagate 7200.10 drives to begin with and have 640GB of space. Would add two more later on when I need them. This actually turns out to be cheaper initially than getting 3 of those drives along with a hardware controller. My guess is that performance may also be better due to simplicity of design. How does FreeBSD play with ICH9R RAID? - Max
