Roterodamus Posted December 30, 2011 Share Posted December 30, 2011 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 (120.034.123.776 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.

xreyuk Posted December 31, 2011 Share Posted December 31, 2011 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. Link to comment Share on other sites More sharing options...
