When you're talking shared storage (over AFP, Samba etc), the clients can't cache much. They have to let the server do that. So data needs to get to the server or from the server in a narrow window to make the frame rate.
Our own testing from a while ago showed you needed about 8 spindles to reliably capture Pro Res HQ. Obviously, things are changing now with front end caching and improved apps. Apple multithreaded their TCP stack as well.
Ultimately, it's not about the size of the raid, it's about the number of spindles. However if you get into buying enough spindles, you'll often find that buying smaller drives to save money doesn't save you much, so you'll want to get the larger drives anyhow.
