That is, the needs will grow and not remain constant, and your counting on the cost per disk to come down may wind up solving today's problem tomorrow. You could approach this as a FreeBSD front end to the Timberwolf and a learning experience. A handy dandy big disk cache and network interface might be an easier and low risk project and let you know the ins and outs of the application.
