Hi,
I have a 120gb Samsung Evo which I am currently using 23GB of and have 89gb free.

When I go to Samsung Magician and click on the over provisioning link it says there is insufficient free space to set up over provisioning.

How much free space do I need?
Is it worth doing for a 120gb ssd?
If it is worth doing on a 120gb ssd is there a way around it? I wont be adding any software and I could get rid of one or two programs to free up a gb. However I am running windows 7 as lean as possible (Civ 5 is my only non essential program)

Thank you very much for any help
