This internal 2.5" SATA SSD delivers the highest transfer speed, endurance, and performance available today. With sustained reads up to 556MB/s and writes up to 523MB/s, up to 100X greater data protection than enterprise class Hard Disk Drives, and RAISE technology for RAID like data protection and reliability, the OWC 240GB Mercury Electra 6G SSD line delivers unbeatable performance. It's also designed and built in the U.S. from domestic and imported parts and backed by a 3 Year OWC SSD Limited Warranty.

Replace your conventional hard drive with a reliable solid state drive. Unlike traditional hard disk drives, OWC SSDs have no moving parts, resulting in a quiet, cool, and highly rugged storage solution that also offers near instantaneous system response. Includes 7 mm to 9.5 mm Adapter / Spacer Attach this adapter to the top of any 7mm, 2.5-inch drive for installations that require a 9.5mm drive height for proper use, whether you need a 9.5mm drive height for a dock, camera, server, device, PC, or external drive. This adapter is not needed for 2.5-inch drive installations that use the standard side or bottom mounting positions to secure the drive in place, and is not needed for any installation of a 7mm drive in Apple Macintosh computers.
