I recently got a Crucial M4 SSD for my mid-2009 MacBook Pro 13" (2.53 GHz). Since I paid some money, I would like to get the best performance possible out of it. Running a speed test using app store Black Magic Speed Test, it showed 260 Mb read and 170 Mb write, although on the Crucial website it says read up to 500 Mb. Trim is not enabled and firmware is the latest (0309).
The connection speed is SATA 3 GB/s.
Is this performance normal or something is going wrong?
