I have a early 2011 13" base MBP and today I bought the Samsung 830 256GB SSD. Windows 7 is not my primary OS, Mountain Lion is my primary OS. I have a question regarding the AHCI driver. 1. I know that AHCI is disabled by default in last year macs and I have no intentions to do the hack to enable it. Will my Samsung 830 256 GB SSD perform decently without AHCI? and will my SSD loose its performance faster?
