http://en.wikipedia.org/wiki/Write_amplificationHowever to regain performance its recomended to create a system image then use a 3rd party program to blank the drive useing an internal blanking comand this isnt the same as externaly writing zeros to the drive. I personaly use windows image tool to make the image and i use parted magic to blank the drive.
As for windows for the home user / gamer there is no advantage or performance diforance between them the only diforance is that the ultimate / pro are more exspensive and consume more space. The home premium is perfectly fine for the home user and will save you alittle cash. The only thing that the home version dusnot have that can be usefull is the XP mode were it literaly runs a virtual windows XP within windows 7 (its there to make XP programs work better) but to be honest i have had windows 7 since it was released and i have never had a problem running XP programs useing the basic XP compatibility function in windows 7 home.
