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 Pro SSD 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 Mercury Pro family uses advanced DuraWrite™ wear-leveling and block management technologies to keep Read/Write performance at peak while others see performance fall.
