It will need ~10TB of disk space. I'm also going back and forth about HW vs. SW RAID. I suspect one advantage of HW RAID when you have a large number of disks is that the host doesn't feel the overhead of all the disk I/Os. The RAID controller takes care of all this so the host sees many fewer I/Os. In an I/O bound environment I suspect this could be a considerable advantage. I've used 3ware controllers on Linux a lot. I agree that both the web site and the documentation isn't as good as it could be. However, their tech support is **Excellent**. What I'm probably going to do is to put a 3ware controller in the frontend box, and then use software RAID in the box that will back it up. That's a good compromise.
