  • For High Speed Personal Computing, Home Office, Gaming, and Personal Photography
  • 3 Year Warranty from OWC

OWC's Mercury SSD line features industry leading SandForce® DuraClass™ Technologies:

  • DuraWrite™ extends the endurance of your Solid State Drive (SSD).
  • Intelligent Block Management & Wear Leveling automatically distributes data evenly across the entire SSD.
  • Intelligent Read Disturb Management spreads the active read/write across the flash components eliminating data corruption caused by constant use.
  • Intelligent "Recycling" for advanced free space management gradually re-writes data across the SSD over time to ensure data never gets corrupted.
  • RAISE™ (Redundant Array of Independent Silicon Elements) protects the data on your drive similar to having a RAID setup.
  • Best-in-Class ECC Protection for longest data retention and drive life.

This internal 2.5" SATA SSD uses the latest SandForce 2281 Processor and DuraClass™ technology to deliver the highest transfer speed, endurance, and performance available today.

With sustained reads up to 556MB/s and writes up to 523MB/s, up to 100X greater data protection than enterprise class Hard Disk Drives, and RAISE technology for RAID like data protection and reliability, the OWC 60GB Mercury Electra 6G SSD line delivers unbeatable performance that's designed and built in the U.S. from domestic and imported parts and backed by a three year warranty.

Replace your conventional hard drive with a reliable solid state drive.  Unlike traditional hard disk drives, OWC SSDs have no moving parts, resulting in a quiet, cool, highly rugged storage solution that also offers near instantaneous system response.

This OWC Mercury Electra 6G SSD is performance certified for use with all Macs and PCs equipped with SATA Revisions 3.0, 2.0, and 1.0 interfaces (SATA 6Gb/s, 3Gb/s & 1.5Gb/s) except for the following machines:

  • 2008/2009 MacBook/MacBook Pro 13", 15", and 17" models. (Model IDs: MacBookPro5,1; 5,2; 5,3; 5,4; 5,5 and MacBook5,1)
    While a 6G SSD does function, it will only do so at SATA Revision 1.0 (1.5Gb/s) speeds rather that the SATA Revision 2.0 (3.0Gb/s) speed the machine can deliver.  Should owners of these machines desire another SSD option, the Mercury Extreme Pro 3G SSD does run at the full SATA Revision 2.0 (3Gb/s) specification.
  • 2011 MacBook Pro 17"
    Thanks to Apple's Macbook Pro EFI Firmware update 2.2 released on 9/14/2011, OWC has test confirmed proper operation of OWC 6G SSDs in all 2011 MacBook Pro 17" (Model ID MacBookPro8,3) models.  After successfully applying this update, your Boot ROM Version will be: MBP81.0047.B1E.

    Total Flash Memory Components - 64GB
    4GB allocated to real-time data redundancy & error correction
    *1GB = 1,000,000,000 bytes. Total accessible capacity varies depending upon operating environment (typically 5-10% less). The actual total capacity will depend on your own defined file settings/preferences.
  • Formatted Capacity**: 55 GiB
    **In terms of standard gigabytes, 1GiB ˜ 1.074GB and refers to the actual formatted capacity of shown under Mac OS 10.5 or earlier and Microsoft Windows OS.
  • RAID Support: Qualified for single drive and multiple drive production workstation RAID 1/SPAN usage.
  • SMART Attributes: Standard***
    ***Temperature reporting is currently an unsupported feature because due to the operating characteristics of SSDs, it is highly unlikely one would ever exceed an OWC Mercury SSD's stated operating temperature ceiling of 158F/70C.  However, OWC is looking into supporting this feature in the future via a firmware update.  Firmware updates can be found here.
