    I have a new 2011 MBP with 4 gb ram. Under normal use, I'm looking at 2gb written compared to 900 mb read (after 3 hours use). It only shows 1.5 gb of ram used (.5 gb is inactive). Should I get more ram? I'm getting an SSD to put in it. Last night, I had the computer on for 3 days straight, it showed 16gb written compared to 2gb read. What's up with this? I'm guessing I should get 8gb ram since I will have an SSD, in order to reduce the # of writes.

    It doesn't matter what's written or read. To determine if you need more RAM, use Activity Monitor and on the System Memory tab at the bottom, check your "Page Outs" and "Swap used". If these are excessive under normal use, it means you're maxing out your RAM and paging to the hard drive. Note that paging may occur during peak loads, which is normal. If you're always paging excessively, then you need more RAM.
