Don't forget to:
1) disable hibernation. save SSD space equal to ram size.
2) Set min/max size of page file to the same value (can use 1024 mb if you have 4 gigs ram). This saves about 3->4 gigs Space as Window use by default about 1.5 x Ram). This can also be moved to the HDD - slight performance hit, dependent on how aften the Page file is accessed.
3) Important for Small SSDs. Either disable restore points or limit the amount of diskspace they can take.
And follow sminlal's advice.
