    Is it worth upgrading to the 840 pro on the non unibody macbook pro 4,1? I understand that the performance increase will be substantial, but also wondering if there are any cheaper alternatives.

    The non-pro 840 SSD is cheaper, as is the Crucial M4, but also know, that your S-ATA 1.5 Gbps (S-ATA I) interface is limiting the sequential read and write speeds, but you will hardly notice that, as the very low latency (random access time) is the main factor with SSDs and their speeds.

    I hear people say that a Sata 2 drive performs better than a sata 3 on a Sata 1 controller, as the latter is to fast for the Sata 1 controller. Is that true? I am really trying to get the best option here. Had bad experience with M4, would like to try the 840. Not too sure if I'll notice any difference between the basic 840 and the 840 pro, or should I just get a used intel x25m?
