Marketing Information

The PCIe SSD drive built for the most demanding needs of video editing and creative professionals.

Boot, Launch, Create, and Save Faster
With its simultaneous internal and external storage performance, the Mercury Accelsior_E2 offers the the best combination of speed, capacity, and connectivity available today.

Stop waiting for I/O-intensive apps like Photoshop, Final Cut Pro, or Avid Pro Tools to render, capture or process. Start working faster with near instantaneous boots and app launches. And save your work faster than ever before.

The Accelsior_E2 utilizes the PCIe slot in Mac Pros and PC towers, the fastest data interface available, to deliver up to 820MB/s of blistering perfomance. That's nearly 3x faster than an SSD equipped Mac Pro 3Gb/s drive bay, and well beyond 6Gb/s drive speeds.

When your work is completed, transfer it for backup or archival purposes at speeds up to 600MB/s via the two eSATA expansion ports to any external storage device with an eSATA port.

Boost Entry-Level Server and Gaming
In addition to video-editing and multimedia creation / management deployment, the Accelsior_E2 takes entry-level servers and even gaming to entirely new levels of performance.

With up to 100,000 IOPS, business-critical applications like online transaction processing databases are given an instant boost. For gamers, Accelsior_E2's speed dramatically reduces game level-loading, object streaming, and save times for more playing and less waiting.

And Laptops, Mac mini, & iMac Too...
The Accelsior_E2 isn't just for desktop computing. With an external PCIe expansion chassis, such as the OWC Helios, you can enjoy the Accelsior_E2's performance benefits with any Thunderbolt port equipped Mac or PC.

Efficient, Reliable, and Upgradeable SSD Blades
Accelsior_E2's SandForce Driven™ SSD blades provide a more responsive and productive computing experience with cooler, quieter, and more energy efficient operation compared to standard hard drives. SandForce RAISE™ technology provides RAID-like data redundancy protection and reliability.

And with the future introduction of higher capacity Mercury Accelsior SSD blades, you'll be able to meet expanding storage needs while extending the useful life of your investment.

Easy-to-Install, Robust, & U.S. Built
Accelsior is as easy-to-install as memory a upgrade, yet robust enough to handle the rigors of pro environments.

This game-changing, high-performance upgrade comes backed by a three-year warranty, and is designed and built in the U.S. from domestic and imported parts.
