    So here's the report from system profiler:

    Intel 6 Series Chipset:
    Vendor: Intel
    Product: 6 Series Chipset
    Link Speed: 6 Gigabit
    Negotiated Link Speed: 3 Gigabit
    Description: AHCI Version 1.30 Supported

    APPLE SSD SM128C:
    Capacity: 121.33 GB (121,332,826,112 bytes)
    Model: APPLE SSD SM128C
    Revision: AXM09A1Q


    So I have the quicker Samsung-made SSD, why is it not working at full 6 Gigabit?

    probably because it is not 6 gigabit.

    from memory, the apple SSDs (both of them) won't saturate a 3 gigabit connection anyhow.

    Because it's a SATA II drive, not SATA III
