Hi guys Im thinking to put a SSD on my moms 06' MB to speed it up. But I was wondering if the SATA III SSDs are backward compatible with the SATA I on the 2006 MacBook. Its the 1.83GHz/512MB/60GB HDD model. Ive upgraded the RAM to 2GB and OS to 10.6.8 SL. And I was wondering if SATA III SSDs like M4 was compatible with it. If not, that means I have to buy a SATA II SSD. Are there any recommendations? Thanks in advance!
