    The NEC chip on that board support both USB 2 and 3, the speed from the USB 2 is faster than the Intel chipset from our Acer.
    The fastest speed I saw was about 150Mb/s but depent on chipset from usb case, best result I have from case with factory drive in it.

    Edit

    But If you use another case for our Acer you can also put a SATA2 or 3 card in it see,

    I can move the motherboard / chipset out of the laptop case, that is not a prob, i have seen people creating good solutions for out of the case laptops, example:


    Yes now these are the speeds i can live with. However this is not what i was looking for and raises one more question in my mind.
    I will ask point-wise
    1. i have usb 3.0 external hdd(s). is there a miniPCI to usb 3.0 card ? Did you plug this card in WLAN (wifi) slot or modem slot? if i am not wrong the modem is there on the laptop and is also connected to miniPCI slot EDIT: sorry modem is not on PCI chain, saw the block diagram,
    2. From your thread, where did you get the card from (Asmedia ASM1061), and secondly how did you provide power to any thing that will be plugged into these sata slots
    3. I have optical drive (ODD) removed as well so that will be one more slot for expansion, how can we use this slot to expand ?

    Lets take all clear, Asmedia ASM1061 sata is not used by me, it was a test, only mini pci e usb3 card with NEC/Renesas chipset with 2 outputs.

    1 Yes mine,

    http://www.conrad.com/ce/en/product/986875/1-port----USB-30-controller-card--------Mini-PCIe

    another example, 4 outputs.

    http://www.speeddragon.com/index.php?controller=Default&action=ProductInfo&Id=416

    Search for mini pci e usb3, look if cables are included.

    I put the card at 3G, but you can use both slots if you have space.


    2 Look again at my project, also link 1 #5136, I solder 2 wires at the place from diode D19, its the power from the HDD, affected by sleepmode.

    If you work with USB externals, Then its enough power.


    3 To put a HDD on it, You see it in your example movie at about 9.40 minutes/sec .
