Also for those of you who think it's technically or financially impossible, it's not. We've got racks of MSAs with up to 25x1TB of drive space, configurable in various raid levels and this is top notch stuff, available for under $20k total including the servers, chassis and drives. There are even less expensive mass storage devices out there some of them giving you 10+TB for under $2k, so really it's just a matter of having the space to host it.
