I can get the Acard for just over $100, the Tempo is not yet shipping, but may be by the time my dual-800 does. Which would you guys recommend? I just want to add extra storage to the Quicksilver internally. RAID would be okay, but not necessary. I plan on using OS X (and 9.2), Final Cut Pro, Photoshop, Freehand, iDVD, etc. Storage for captured video is of most importance. I have 2 80GB 5400 FW drives, and 2 80GB 7200 to add inside. I also have a couple of 40GB 7200 RPMs, that I would like to add. I BTO'd the Dual with just a 40 GB 5400, so it's coming out.
