I would think you should use raid for this, at least raid 5, which 
requires N+1 for N drives worth of storage.  and you probably want a 
hotspare in case a drive fails.

USB drives are quite slow, you want to use SATA for this.   you can get 
PCI-E sata expansion cards, ideally on PCI-E x4 slots which have 
sufficient bandwidth (pci-e x1 would be a bottleneck for more than a 
couple drives)

I'd  suggest getting a 'storage server' with sufficient drive bays and 
channels for what you're doing.

a server like 
http://www.asaservers.com/config.asp?config_id=ASA4002-X2Q-S2-S holds 8 
hotswap drive bays and is quite customizable.
