I just got a 2009 Mac mini with 2gb ram and the stock 120gb hd. I have around $100 I can put into the machine right now. I'm debating between a ssd and 8gb of ram. I have an external USB hd for mass storage. I mainly use this machine for home recording in Logic 9, home iTunes media serving (500gb or so), and basic photo work in IPhoto (another quite large library). I get a lot if beach balls. I'm thinking that ram should come first, then the ssd in a few months when I can afford part two. If I get the ram, can I just get one 8gb module, allowing me to add a second at a later date or do I really need a matched set? I value flexibility over a marginal performance increase. Thanks for any advice.
