I think if such a high amount of space with such a high
number of parallel users is a must then a lot simpler
approach would be to divide the news spool (say, by
newsgroups) among multiple machines and set up one
machine as a kind of proxy, to accept requests
from the users and forward them to a machine which really
has this particular newsgroup on it. That would also
solve the problem with the CPU load and memory size.
For further scalability there may be multiple proxy
machines and a load balancing appliance of the same
kind as the ones used for the web servers.
