It depends on how you are using the system, but it makes sense to allocate around 2 GB for a RAM disk and move Windows temporary folders and browser caches to it. This could provide better performance and spare the SSD from unneeded writing that would shorten its life.
I don't do games (well, if you consider FreeCell a game), basically browser and text documents. Should I setup this 2G on a NTFS partition with RAM disk in my case?
