The best performance and longevity in a 2.5-inch SATA SSD for every use
When the first Mercury Extreme Pro 6G SSD was launched nearly a decade ago, it was built to be the fastest, most reliable, and longest enduring 2.5-inch SATA Solid State Drive on the market. The evolution of OWC’s premier 2.5-inch SATA SSD continues that legacy with up to 5x faster performance over the duration of its capacity versus other drives. If you have a Mac or PC with a 6G SATA drive bay, the Mercury Extreme Pro 6G SSD is the fastest 2.5-inch SSD available today.
Starts Fast, Stays Fast
Even though many SSDs use low cost, less robust components in their design, they can still offer enticing short term bust speeds which are perfectly suitable for light duty uses. However, these drives are not designed to deliver consistent sustained speeds over their capacity rating, which results in a dramatic slowdown to even hard drive speeds under demanding use.
The fifth generation of Mercury Extreme Pro 6G SSD was built to start fast and stay fast. Its development began with using the best flash storage components and technology available. Next, after being nearly completely filled to capacity with data, it had to deliver the same high speed as if it were empty. This drive doesn’t flinch at any time or capacity level and drop read/write speeds like other drives do…it easily handles the most extreme, mission-critical uses you can throw at it.
Get Your Money’s Worth
When a low-priced “commodity” built SSD’s performance drops off significantly, many users replace the drive far before all its storage capacity is used to regain that “like new” speed feeling. The Mercury Extreme Pro 6G SSD was engineered to keep you working full speed ahead over the duration of the drive to deliver an overall lower cost of ownership.
With your investment in apps and time getting that beloved workhorse Mac or PC configured just the way you like; it makes sense to get all the use you can out of the machine before retiring it. By revitalizing your Mac or PC with a Mercury Extreme Pro 6G SSD, you’ll transform your machine with like-new performance with the best performance upgrade available. From faster boots and application launch times to greatly improved system responsiveness, you’ll love using your “new” computer for a fraction of the cost of buying the latest model.
Go Big or Go Home
