Over Provisioning & Wear Management Explained

Some of the drive space in OWC SSDs are allocated for RAISE - which provides real time data redundancy, ECC Error Correction, and reserve cell space.

Example: An OWC Mercury Aura Pro Express that's 240GB in size with 7% over-provisioning is actually a 256GB drive with 7% allocated for data management, and to maintain the drive's high-performance level.

Unlike most SSDs on the market today, the OWC Mercury Aura Pro Express uses advanced DuraWrite™ wear-leveling and block management technologies to keep Read/Write performance at peak while others see performance fall.
