My intel 40gb has win7 64bit (needs abit more space then the 32bit) and all my apps that i use on a regular basis.
Total space used is 23.5gb giving me 13.7gb left, so i would'nt worry to much.
This is on a 6 month old install.
That's pretty funny. I've heard that SSD performance starts to drop after you fill them over 60% and you're at 58%. Nice!

I can't wait till these sandforce SSDs drop in price because right now I wouldn't consider anything below 64GB to last me.
