No it makes sense.

I am contemplating if I really need 4 x 1tb in this system. I mean how  
much space with some photo's, web pages and MySQL take up if there are  
5,000 subscribers to start up?

Would 2 x 1TB enterprise drives be enough mirrored?

Sure, I will be doing a lot of research on that for sure.
