OWC's SSD vs HDD Shootout!

Seeing is believing! Watch a side-by-side shootout between an
SSD and HDD in a PowerBook G4 loading Adobe's Creative
Suite on startup.
Watch the SSD vs HDD shootout!


  • Designed & built in the US from domestic & imported parts.
  • Chip Based Data Encryption: 128-bit AES-compliant.
  • Intelligent "recycling" for advanced free space management.
  • Best in class error correction (ECC) and SandForce RAISE (Redundant Array of Independent Silicon Elements) technology provides RAID-like data protection and reliability without loss of transfer speed due to parity.
  • SandForce Processor with 7% over-provisioning maximizes read and write performance to greatly extend the endurance and overall reliability of the drive.
  • Up to 100X greater data protection than what the highest rated enterprise class conventional hard disk drive (HDD) provides.
  • SandForce DuraClass technology with Ultra-efficient Block Management & Wear Leveling offers highest endurance, performance and power efficiency in a SSD.

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 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.
