Need help partitioning archlinux server.

view story

http://serverfault.com – Alright, so am building a webserver that will be using mysql, nginx, php, and a few other things. I expect the database to grow quote large and there will be many small files that will be served by the webserver, less than 1-2mb downloads. I have two 1.5 tb sata HDD's and 350 gig sata hdd, the mobo has enough sata ports to plug them all in. I'm looking for some advice on how to partition this thing. I am using cfdisk. If its just going to be a webserver, do I need a large /home directory? I want to use a different faster fs for the /var dir as per the archlinux recommends. I'm not exactly su (HowTos)
