Q: 13" MBP SATA interface downgraded to 1.5 Gigabit

I just checked my system information and the sata connection is reporting 1.5 Gigabit as the speed. I discovered this when I benchmarked my Vertex 60GB SSD and noticed that the speeds were a lot slower than before (I used to have a 15" umbp). Did apple downgrade the sata connection? This is a huge disappointment and very surprising.

13" MBP 2.2GHz, Mac OS X (10.5.7)

    THe MBP 17", that you have, has always been at 3Gbps, even with the original EFI (is there an EFI update for the 17"? I'm not sure). So the 17" is not concerned by the 1.5Gbps issue.


    Right. But it has the nVidia chipset as well. The throttling then happened on the July MBP 13 and 15 that also have the nVidia chipset. So both may have the overheating issue with fast drives. In any event, the OCZ wont work in the MBP 17 - for the same reasons it seems.
