    PCIe 2.0 x16 sata 3 controller board question..

    I have a ASRock AM1B ITX MB with 4 Sata ports. the board has a single PCIe 2.0 x16 slot.

    all 4 ports are used, and I would like to add a 5th SATA device - is there a sata 3 controller board that would work with that slot ? Not sure if the board has to completely fill the x16 slot, or if I could use a different board.

    THX

    PCIe slots are backwards compatible and interchangeable.

    For example, you may fit PCIe cards x1, x4, x8 into a x16 slot.

    It is also possible to do the reverse, fit a x16 on a x8 slot (requires open ended slots, card speed degrades based on the available slot speed).

    Just be careful if you are going to use a raiser card, sometimes those cards aren't very compatible or they can't reach their advertised bandwidth.

    Also, there have been issues with some PCIe cards that when fitted on a higher speed slot, then the whole bus would run at the slower speed of the card.
