OWC Mercury EXTREME™ Enterprise Class SSD
200GB SATA 3.0GB/s Solid State Drive

High-Performance Enterprise Class Storage for Notebook and Desktop Computers.
Exceptional choice for Ultra-High RAID-0,1,5,10 Performance

When only the fastest and most reliable Solid State Drive on the market today will suffice for your data storage and backup, look no further than the OWC Mercury EXTREME Enterprise SSD.

  • Get maximum mobile performance and battery life from your notebook.
  • Turn your Mac Pro or PC desktop into an EXTREME performance single drive or RAID workstation.

The Mercury EXTREME SSD 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 a high performance SandForce Driven™ processor with DuraClass™ technology to deliver the highest transfer speed, endurance, performance, and power efficiency available today.

With sustained read and write times over 260MB/s, up to 100X greater data protection than enterprise class HD's, and RAISE™ technology for RAID like data protection and reliability, the OWC Mercury EXTREME 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.

High Performance Internal Storage
Replace your conventional hard drive with a reliable solid state drive. Unlike traditional hard disk drives, OWC solid state drives have no moving parts, resulting in a quiet, cool, highly rugged storage solution that also offers faster system responsiveness.

Better by Design
"Mean Time Before Failure"—We all know that nothing lasts forever. But that doesn't mean you shouldn't get the most out of your investment. OWC SSD with Durawrite™ Technology, optimizes writes to the flash memory over conventional controllers increasing the overall endurance and reliability of the complete SSD. Highly intelligent block management and wear leveling also extends the overall endurance. With this technology, even MLC-based SSDs can operate in enterprise environments for 5+ years without daily write restrictions. This adds up to a MTBF that is up to 5X longer than the other leading solid state or enterprise class hard drive mechanisms on the market.

Additionally, as there are no volatile memory elements in this storage device, the need for cache is completely negated. The drive is just that fast from the get-go!

    IMPORTANT LAPTOP USER NOTE: There have been reports of system hangs in relation to hibernation mode. We recommend not using ANY program that puts your laptop into hibernation mode when using an SSD.

    Normal, automatic sleep mode functions perfectly with no issues.

    We also highly recommend you avoid draining your battery completely (5% or less remaining charge) to avoid being automatically switched into hibernation mode by your machine's power saving settings. If your notebook does go into hibernation mode, the machine can hang once it is plugged into an outlet or when using a charged battery as the machine comes out of hibernation mode. If you should experience this, you will need to restart your machine and any unsaved work from that session will be lost. SandForce is working on this issue and it will be addressed in a future firmware update. We will post the update on our firmware update page as soon as it becomes available.
