Corsair Force GT issue on MacBook Pro Mid-2010 (Sata 2)


Recommended Posts

I just bought the Corsair Force GT 120 GB to use as the only hard drive in a MacBook Pro Mid-2010. I knew that my MacBook Pro model only supports SATA I & SATA II & that the SSD is backwards compatible. I expected (and still expect) the SSD to link up at SATA II 3 Gb speed.


However, System Profiler in Mac OS X Lion gives the following information:


NVidia MCP89 AHCI:


Vendor: NVidia

Product: MCP89 AHCI

Link Speed: 3 Gigabit

Negotiated Link Speed: 1.5 Gigabit

Description: AHCI Version 1.30 Supported


Corsair Force GT:


Capacity: 120,03 GB ( bytes)

Model: Corsair Force GT

Revision: 1.3.3


Benchmark tests show my write & read speeds are at about 100 & 110-130 MB/s. I have searched for a while on this and other forums and not been able to find a way to get negotiated link speed at 3 Gb and then to check whether this solves the rather sluggish performance.


Some extra info that might be useful:


-I have installed all available updates.


-The SSD is the only drive in my system. After booting to the Mac OS X Lion DVD I had created, I used the disk tool to partition the new drive with the settings at GUID partition table & HFS+ Journaled. I haven't experienced any other problems.


-I have reset the SMC, PRAM & NVRAM. This didn't change anything.


-I haven't installed any Windows version using Boot Camp (yet).


-System has Boot ROM Version: MBP71.0039.B0B and SMC Version (system): 1.62f6


Thank you in advance.

it's a problem that cannot be fixed.


I had the same problem with my Force 3. Corsair weren't interested in helping one bit.


I've RMA'd mine, and bought an OCZ one instead, they've at least released a fix, where Corsair couldn't care about their customers.
