Hi, My imac late-2009 (core 2duo) HDD failed, so I decided to change it for a new one, and to change the optical drive which I never use for a small SSD for the system. First things first, everything seems to work fine - I made a clean install of Mavericks on the SSD, and the imac now boots up much faster than before (about as fast as my MBA). So I was thinking that everything's good. But then I checked SSD speedtest results on the internet and it looks like I'm quite far from it: On the SSD, I get results that are around: Write: 138MB/s Read: 268MB/s Internet results are generally far from that. Also, on the HDD in the main HDD bay, i get 154/179 write/read MB/s... If I verify the disk all is fine. In the system report, under "SATA", for the SSD I see Link Speed: 3 Gigabit Negotiated Link Speed: 3 Gigabit Physical Interconnect: SATA which is same as the main HDD. What shall I do?
