How much space should I keep free?

[RollerBall]

I have a 128gb M4 and I was wondering how much space I should keep free. I've heard conflicting reports about overprovisioning and 10% etc.

Atm I'm running out of space quite quickly, windows, core programs, fallout:NV, D3 and MW3 are already pushing me close to max capacity...

i have no idea,but ssd's have reserved/hidden amount of space to maintain the drive and replace any damaged cells so id say it doesnt matter?

take your games off it, your not really gaining anything by having them on it

all you get is less load times but no fps gain
