Add a technological supercharger to your existing Mac or PC with the OWC Mercury Legacy Pro SSD. It's the fastest, most reliable IDE/ATA mechanism available to breathe lightning fast performance into that trusty machine and extend its usefulness.

Boot, load apps, and access data nearly instantaneously...tedious system responsiveness is a thing of the past! Enjoy award-winning ultra-efficient Block Management & Wear Leveling technologies that virtually eliminate any speed reduction over long term use of the drive. And with no moving parts to break or fail, the OWC Mercury Legacy Pro SSD offers uncommon ruggedness for notebook users with up to 100x greater reliability than traditional hard drives.

"Mean Time To 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 for years in demanding use applications without daily write restrictions. This adds up to a MTTF that is higher than most enterprise class hard drives and SSDs on the market today.

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!

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.
