Same Pro Performance,
Plus RE = RAID-READY Enhanced
  • One of the fastest Internal SATA 2.5" SSD available
    Up to 285MB/s data rate.
  • Ultra-efficient Block Management & Wear Leveling
    Prevents write speed degradation commonly experienced by other brands' SSD.
  • EXTREME Power Efficiency
    Uses up to 75% less power than hard drives and up to 50% less power than current SSDs* when active.
  • Exceptional Choice for Ultra-High RAID Performance
    Great by itself, but enhanced with enterprise level 28% over provisioning for multi-drive, high-performance RAID array usage.
Ideal For
  • Get maximum mobile performance and battery life from your notebook.
  • Turn your Mac Pro or PC Desktop into an EXTREME performance single drive, multi drive, or RAID workstation.
We compared our 100GB OWC Mercury EXTREME 3G Pro SSD against Industry Leading SSD's from Intel and Crucial. All drives tested in Mac Pro 2.93GHz Quad-Core with 8GB RAM. Faster times are better.
OWC SSD Benchmark Proven Performance
  • One of the fastest Internal SATA 2.5" SSD with available data rates up to 285MB/s.
  • SandForce DuraClass™ technology with Ultra-efficient Block Management & Wear Leveling offers highest endurance, performance, and power efficiency in a SATA SSD.
  • SandForce® Processor 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.
  • 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.
  • Intelligent "recycling" for advanced free space management
  • Highly secure… all data automatically stored in AES-128 encrypted format.
  • Designed and built in the U.S. from domestic and imported parts
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.
