Magician - Over Provisioning

The Over Provisioning feature is used to resize drive partitions. SSDs perform better and last longer, if they have free space to use as swap space.

During idle time, swap space is used to perform routine SSD maintenance (TRIM and Garbage Collection) in the background, which allows the SSD Controller to prepare free blocks for future use. Since the SSD performs better when writing to free blocks, the result is a better user experience.

The Over Provisioning feature helps to set aside free space by resizing the drive partitions.

Note: Over Provisioning is not supported for Windows XP.

CAUTION: Magician only supports NTFS and raw (Unformatted, Unallocated) partitions.
