    Straight to the point: does anyone know whether the ExpressCard34 slot in the TX2500 series is connected to the motherboard via PCIE or USB? From what I've heard it can be done via either.

    Reason I'm asking: I've been doing a lot of data moving back and forth with my external hard drive and tablet via USB, and the speed is a real pain. My external drive has an eSATA port and was wondering whether its worth using an ExpressCard34 eSATA adaptor. Thing is though, from what I gather ExpressCard34 slots can be wired up via USB (which'll give no speed increase) or via PCIe (which gives a theoretical 2.5Gb/s max). I know that data transfer tech doesn't hit the theoretical max a lot of the time but I figure it'll be faster anyway.

    If anyone knows I'd appreciate the information.

    Both.
    Required in the standard.
    Read more about it here: About ExpressCard

    The host must have both, cards can use USB or PCI-E. :)

    Ah, thanks for that. I'm assuming that if its an eSATA adaptor then they'll be using the PCI-E instead of just the USB then for speed.

    Thank you!
