    Gigabit LAN to USB adapter


    Thank goodness: you had me wondering if I'd been exaggerating USB capabilities all these years. There's probably something funky about the USB-to-PCIe bridge that connects USB to the computer's internal bus. I've seen this kind of thing on other low-budget tablets and low-end laptops before, now that you mention it...
    Not a good way to figure out your equipment is suboptimal, though. Hope you figure out a way to straighten things out. On my Lenovos, for example, I can get somewhere inbetween real USB 3.0 and USB 2.0 performance by using an adapter card that plugs into the PCIe slot in the notebook and that offers a pair of USB 3.0 ports to plug into. It cost about $30 and is another StarTech product (I buy them from Newegg) called 2 Port ExpressCard SuperSpeed USB 3.0 Card.
    HTH,

    Guess I didn't make it clear that one motherboard came with built-in USB 3.0 and the other has the added card to gain the capability.

    Gigabit LAN to USB adapter

    Hi there

    That's only a MAX of around 40 MB/s transfer --typically an average on USB2 you'd probably get an average of around 30 MB/s transfer -- quite slow when copying say 20 GB of multi-media files. Several minutes !!!.

    Over a network you are limited to LAN or Wifi speed -- if it's Wifi you'd probably be lucky to get a constant transfer speed of 11 - 12 MB/s (Mega BYTES / sec) whether you use USB 3 or USB 2 !!!!.

    I still find it strange that a laptop fitted with USB 3 capability on the Mobo only has USB 2 connections --unless the USB 3 mobo connectors are not really USB 3 !! I've seen a few mobo connections that look like USB 3 (have the blue colour) but are in fact USB 2. I've taken enough computers and cannibalized enough parts to know there's often strange things on a lot of Mobos.

    Cheers

    Hi,
    I have been doing some test about USB2.0 & 3.0 regarding to find out what is going on here.
    The Motherboard Chipset has USB 3.0, but the case Connectors are USB 2.0, they are black. I have also opened the case to see if there was 8 Lines to connector but there are only 4 , so no way to exchange connectors.
    My previous test was wrong, USB 2.0 are full speed, I was transferring the file to the internal SD-Card and Card / Adapter are "half-speed" or something else is slowing down the I/O speed.
    In both Laptops the USB 2.0 is very close to 40MB/s.
    And USB 3.0 is 300MB/s, probably behind the 400MB/s because SSD can not reach that speed.

    The connectors from the case ports to the motherboard are actually contain only 7 wires, the pins on the board are 7 with the plug having a blank area for indexing the plug. My motherboard manuals show USB 2.0 as HighSpeed and USB 3.0 as SuperSpeed. The USB symbol on my Notebooks that have USB 3.0 also have added SS letters to identify in addition to the blue centerpiece.

    I just got one LAN to USB adapter 10/100/1000Mbps and indeed the data transfer speed, in real world, is around 40MB/s, so about 320Mbps when adapter is connected to USB 2.0 Port. Not bad, much better than the 11MB/s of a 100Mbps LAN.
    Thank you EdTitel, you made me buy that adapter.
    @Berton: USB 2.0 has only 4 Wires, cables from Motherboard Headers with 8 wires are for 2 USB 2.0 ports. USB 3.0 has 8 wires (may be 7), i do not know it exactly and I do not need to.
    Look at an USB 3.0 Port you will see 8 connections, 4 in foreground (that are for USB 2.0) and 4 deep in connector, difficult to see.
