Over-Provisioning

SSD overprovisioning can provide higher efficiency and better endurance.
Over-provisioning is a function that sets aside space for the SSD's provisional use. These free blocks allow the SSD to operate at normal speed while other functions such as wear-leveling or garbage collection are taking place. The blocks also serve as replacements for bad blocks that may be detected by bad block management.
