    Has anyone considered or attempted swapping onboard USB 2 connector for USB 3? Footprint of the connectors appears the same with additional pinouts required for USB 3. Particularly interested from any E3000 modders.

    Even if it were possible to make the swap, I'm pretty sure you would notice 0 difference. These devices are too underpowered to take advantage of that. Consider a nas or pc.

    Assume you mean CPU as my USB 3 HD device is self-powered.

    I'm backing up through an E3000 with a Quad-core CPU and can hit just 81Mb/sec to a USB 3 connected HD formatted as ext2. Not bad considering the hardware but not great. 81Mb/sec seems like the ceiling for a 100Mbit connection, not Gigabit which E3000 supports. CPU utilization stays at 100% with the run queue between 1.75 - 2.0 for the duration. On the other hand, noticed no apparent slowdown in routing performance.
