OWC Mercury Electra SATA II 3Gb/s 2.5-inch SSD

Thanks for your advice regarding changing my old MacBook Pro hard drive. I cloned the hard drive to your new OWC Solid State Drive which took about two hours, then removed the hard drive and installed the SSD in about 15 minutes. The Macbook fired up straight away and together with your earlier RAM upgrade now performs as fast as a new laptop!

Good advice and great service.
