Move the page file to something that's not the SSD - set the page file to a static size (always a good option) - don't defrag your disk.
pagefile to a static size used to be ok, not so much these days, but i agree move pagefile to a harddrive, but if i remember rightly, win7 if it detects ssd will disable pagefile on the ssd
Page file will default to some % of your RAM, putting it on your SSD will just wear your SSD down due to more read/write cycles hitting it for no real reason. Page files themselves are a tad pointless now anyway as most systems have 6GB+ of RAM and if you run out of that you're probably doing something wrong Static pagefiles are a good idea as they stop fragmentation of the drive they're sitting on - the size of said static file should be calculated by using sysinternals process monitor and seeing how much it thinks it needs. Or, if running databases on your computer -> should be the same size as your RAM. I usually set mine to 2GB (static) and have had no issues, it probably doesn't even need to be that big but i'm too lazy to work out how big it needs to be (16GB ram in my system)
It pretty much looks after itself under Windows 7! Just don't stress about it too much and enjoy the great speed. Also and idea to run the 'Windows Experience Index' as that optimises settings around an SSD somewhat.
Well....no. Pagefiles are integral to Windows and the many programs that are written to utilise them. They are very important for error reporting given no-one runs ECC or FB memory in their home systems. That's a good enough reason on it's own.
