Good afternoon MacRumours, I fitted an SSD in my friend's 2008 Aluminium Unibody MacBook. It looks like it's a 3GB/s interface on the SATA, but it's running at a negotiated 1.5GB/s. A look online seemed to indicate that this is a hardware bottleneck due to the nVidia firmware. May I confirm if this is the case, or if anybody knows of a way to fix it? The system is on the latest version of Yosemite and all firmware updates have been applied.
