With 16 people accessing the data it sounds like a traditional file server type of environment. The problem is the amount of data you have - it exceeds the capacity of many NAS products. Talk to NetApp, BlueArc, Zambeel, EMC, Compaq, MTI, or Auspex. If you can't afford a big NAS system then I recommend using an NFS, Windows 2K or Netware server with a simple SAN (small switch or hub, and maybe four 2TB storage cabinets. I would mirror them because mirrored disk is always a good idea). Make sure you have a volume manager or RAID controller available that allows you to combine storage volumes and mirror them.
You may even find that DAS will work for you - I would think that there could be an LVD SCSI solution that will do what you need.
