SATA III SSD only performs SATA I in MacBook Unibody late 2008

I have a MacBook Unibody late 2008 with a OCZ Vertex 3 SATA-III SSD installed.

The Macbook Unibody late 2008 supports up to 3 Gigabit speed (SATA-II port).
The OCZ Vertex 3 supports up to 6 Gigabit speed (SATA-III).

BUT:
although the SSD is able to perform at SATA-III leve (6 Gigabit)l and the MacBook Unibody late 2008 is able to perform at SATA-II level (3 Gigabit) the MacBook only performs at SATA-I level (1.5 Gigabit). 😟

How to change this so that adequate performance (SATA-II leven = 3 Gigabit) will be achieved???

Thx,

SpaceDoc

ps: of course latest Mac OS X (10.6.7) installed.

You might get a faster answer by posting this question at OCZ's forums. Their staff monitors and answers questions.

well: OCZ's german forum asked immediately: "did you tell apple about it"! 😟

btw: this statement here now really confuses me ...

There are some notes at OWC (eshop.macsales.com) .... they point out that the SATA III SDDs which they sell ONLY work at SATA I speed on Macbooks up to around 2008/9.

Maybe this is true of all SDDs !

I only know this because I was looking at them earlier today

OCZ SSD's have problems with older and some newer MB's.

Although you'll have fast access than a normal drive, your link speed will cap you at 1.5 because of the controller of your mb and the chipset of the ssd.

Intel, Crucial and Kindston drives are much better for older MB's.

If you're noticing a speed increase, then don't worry about your link speed.
