Right now I have a
Hitachi 320GB 5400rpm and a
MATSHITADVD-R UJ-868 superdrive connected to the Nvidia MCP79 SATA controller in my MacBook Pro 5,3. The link speed of the hard disk drive is negotiated to 1.5 Gbps as, according to this answer the device is a SATA I (1.5Gbps) device.
This is what my system profiler says about the SATA controller:
Vendor: NVidia Product: MCP79 AHCI Link Speed: 3 Gigabit Negotiated Link Speed: 1.5 Gigabit Description: AHCI Version 1.20 Supported
Now I'm wondering the following:
If I would replace the Hitachi HDD with an SSD of any brand will the negotiated link speed be 3Gbps? The SSD being a SATA II or III device. Or will this be capped because it has to divide the 3Gbps over the HDD/SSD and the Superdrive?
