I have just built a computer with a 60GB SSD and a 2TB HDD. After installing windows 7 home premium, the drivers, chrome, and running windows update a few times it now only has 11GB left on the SSD. This is after doing disk cleanup and removing all but the last backup image. The only windows features installed are the ones by default during a clean install. I have since removed all the games via add/remove features. I've also made sure that the recycling bin is empty. So I'm still left with only 11GB of space left. I have 16GB of ram and was hoping that there would be at least 16GB free for virtual memory. The box that windows 7 came in says it requires 16GB free disk space.
I had planned on installing IIS as well but having the actual sites on the 2TB drive. The ulitmate goal is to have just windows on the SSD and everything else on the HDD.
