Note on compatibility with this SSD

While this 6G SSD does function, it will only do so at SATA Revision 1.0 (1.5Gb/s, 150MB/s) speeds rather that the SATA Revision 2.0 (3.0Gb/s 300MB/s) speed the computer can deliver. Instead, we highly recommend the use of a comparable capacity OWC Mercury Electra 3G SSD for this Mac.
