I'm thinking about upgrading to a SSD but wanted to know if my MacBook (see sig) had a Serial ATA speed of 3 Gigabit or 1.5. The System Profiler says Vendor: NVidia Product: MCP79 AHCI Link Speed: 3 Gigabit Negotiated Link Speed: 1.5 Gigabit Description: AHCI Version 1.20 Supported under Serial-ATA. So I'm not sure if that means the the port is a 3 Gigabit port but the HD is only 1.5. Does that mean the SATA cable is a 1.5 Gigabit speed, and I'd need a new cable, or what? Also if it is 3 Gigabit port that means it's SATA II, right? Any help appreciated thanks.
