Just purchased a late '09 server model at the marketplace. It's awesome and I'm sure I'm under utilizing it as a desktop computer but it was priced right and I was super stoked with the deal. It has two 500 gig drives. I've never had a system with a second hard drive and am curious how it works. Once the primary drive fills, will it automatically start to put data onto the second drive? Can I use the second drive to store only video I download, and just click on the icon to get to them when needed which should help keep the primary drive "clean"? Thanks in advance for your help. Not a computer dummy, but this is a new situation for me. All input is welcomed.
