Hi, I just upgraded my mid 2011 iMac with an SSD (Kingston V+200 120 GB) and i'm only getting write 130 MB/s and read 160 MB/s. Drive specs are seq red/write at around 500 MB/s. I installed SSD in place of main HDD, not in the extra sata port behind ODD. System profiler shows that SSD is connected to a 6 Gbps port and negotiated link speed is also 6 Gbps. There should be people with these kingston drives here. Thanks for any help.
