I currently use a lexar expresscard CF reader along with UDMA CF cards when using the laptop and it is much faster than using USB 2.0. Basically my USB 2.0 motherboard connections are already in use so I have a choice of SATA or USB3.0
I figured getting one with USB 3.0 would make use of the motherboard connection leaving the SATA one free for future use plus the panel limked to above includes a USB3.0 hub so I would not only be able to transfer at the maximum card speed but also have an external usb 3.0 socket.
I’m just uncertain as to whether the panel has just one connection internally which is to the USB 3.0 motherboard terminal which ‘powers’ the USB 2.0, uSB 3.0, card reader and esata external ports and was suspecting it doesn’t.
