OWC doubles capacity of Mercury Extreme Pro Solid State Drive to 400GB

Other World Computing (OWC) announced today it has added a new highest capacity 400GB model to its award-winning OWC Mercury Extreme Pro SSD line. Designed and made in the U.S. from imported parts, the new 400GB model doubles the capacity of previously announced OWC Mercury Extreme Pro SSD models while delivering the same best combination of performance, reliability, and warranty coverage available on the market in a 2.5″ SATA Solid State Drive (SSD).

The new OWC Mercury Extreme Pro RE SSD 400GB model comes with enterprise level 28% over-provisioning, five year warranty coverage, and is compatible with Mac and PC computers that can utilize single or multiple 2.5″ SATA compatible drives including all RAID configurations. Priced at US$1599.99, the 400GB model is available for pre-ordering with shipping to begin 5/21.

Existing models in the line (previously named the Mercury Extreme Enterprise SSD) are available for immediate ordering and share the same redundancy, reliability, and form factor as offered by the 400GB model which provides easy installation in notebooks as well as in desktop/towers with an adapter:

• 50GB OWC Mercury Extreme Pro RE SSD – $219.99
• 100GB OWC Mercury Extreme Pro RE SSD – $399.99
• 200GB OWC Mercury Extreme Pro RE SSD – $729.99

Ordinary SSDs offer fast read/write performance during first initial uses, but then experience significant write speed degradation over repeated usage. Independent tests by leading Mac performance experts confirm the OWC Mercury Extreme Pro RE SSD is able to provide sustained and consistent read and write times of over 260MB/s with 0.1 ms latency and experience virtually no reduction in data transfer rate over heavy usage of the drive.

Utilizing SandForce DuraClass technology, the OWC Mercury Extreme Pro RE SSD is able to provide up to 100X higher data protection than provided by ordinary SSDs as well as leading enterprise class hard disk drives. By combining the highest level of Error Correction Code (ECC) and SandForce RAISE (Redundant Array of Independent Silicon Elements) technology, the OWC Mercury Extreme Pro RE SSD provides RAID like data protection and reliability without loss of transfer speed due to parity.

Because the OWC Mercury Extreme Pro RE SSD uses as little as 1/3 the power compared to the most power efficient 2.5″ hard drives and up to 1/7 less power than other leading brand SSDs without any performance sacrifice, notebook users can now maximize their “unplugged” mobile use time while desktop/tower users can enjoy the benefits of a more energy efficient system.

“This increase of capacity to 400GB is going to be well received by high end video and photography professionals as well as power users seeking to create the ultimate performance RAID array,” said Larry O’Connor, CEO, Other World Computing, in the press rleease. “Doubling the capacity in what TweakTown.com calls ‘class leading…a must have’ makes the Mercury Extreme Pro RE SSD that much more attractive to a wider audience of users.”

  1. I like both OWC and SSDs but I too will wait for the price to come down to replace my 250 with the 400. Have to clear up one drive in my Pro first to make space for it.

  2. Simply put…it ensures the highest level of data reliability.

    More technically, over-provisioning take a % of drive space and utilizes it for real time data redundancy, ECC Error Correction, and reserve cell space.

    Example: An OWC Pro SSD that’s 200GB in size with 28% over-provisioning is actually a 256GB drive with 28% allocated for data management and to maintain the drive’s high-performance level.
