TBs of storage

I spent a significant amount of time yesterday looking at storage. I came to the conclusion eventually I'd want a rack with UPS running a FreeNAS box with SATA RAID powered by AMCC's 3ware 9650SE controller. See:
http://www.3ware.com/support/userdocs.asp
http://www.freenas.org/

RAID 6 requires an 8+ port card and 2 disks for parity, 2+ disks for data, and a hot spare for a total of 5+ disks. That's $500 for the card and $750 for disks to get 1TB of space. This config is expandable to 2.5TBs. I think I'd take the last 500GBs and partition it into multiple drives for multiple bootups.
