Windows 7 pagefile size with large RAM and SSD

I recently got my new PC with 12 GB RAM (running Windows 7 64bit). The default installation suggests a 12 GB page file on the system drive (which I think is both inefficient and expensive on a SSD drive...)

I'm wondering if I need any virtual memory at all, 12 GB being more than I had on my previous machine including the page file (I had 3GB RAM + 3GB pagefile).

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
You should also NEVER completely disable it. You might run fine forever like that, but it has the potential for unfortunate consequences.

Yes, you need a page file. Windows always needs to have at least a little bit of HDD space (or in your case SSD space) to function properly. Since you are using a SSD, I would lower the size of the page file down to around 0.5GB or so. Normally Windows likes to have 1.5 times the amount of physical RAM as a page file (seems ridiculous to me) as mentioned by this link. I don' know the specifics comfortably enough to explain why you need it (other than reasons you would need RAM and when your computer wakes from sleeping), but I know that your OS should have some allocated for a page file.

An alternative to using your SSD would be to get a 4GB (or whatever you choose) flash drive, and set your page file on that. Then you wouldn't need to worry about your SSD having a page file. :)

-Hope this helps

After answering this question and attempting to do some research on other reasons Windows needs a page file, I noticed the conversation in the comments of the question...
