low level format worth it?

I've always used Killdisk to zerofill a hard drive before installing windows. I've been told it's better to start off on a clean slate, especially if there's been data on the drive before. Performance-wise, does zerofilling a drive make a difference?

If it's your information you're overwritting I don't see the point on doing that, zerofill is used so that data cannot be recovered by other people.

you don´t want to low level format your HD unless it´s ABSOLUTELY necessary.

definitively overkill and no you´ll get no performance improvement
