Always fails when copying large files (>10GB), (1) between 2 portable hard drives connected to the hub; (2) between a networked file server (through the Ethernet port) and a HD connected to the hub

as expected on 2.0 it only supports one non powered usb hard drive.

If you plug in one portable usb hard drive and a mouse, you might be over the 900mA maximum power draw. and 2)

Tested it with two USB 3 hard drives connected to my Mac Book Pro and write speeds to the external drives were between 91 and 115 MB/sec

I thought that it was so you could share your hard drive to your network so you could run a USB on your local computer or a media player and have it setup to remote to your networked computer

The three USB 3.0 ports don't matter much to me since I tend to only use Apple Superdrive and an external hard drive which both need to be powered by a primary peripheral rather than one like this

Simply not an acceptable situation with an external hard drive

I thumb drive is alright but using a external USB hard drive tends to not work on the adapter (which isn't an issue with the product but rather the power limitations of the USB port on the computer)

This gives me the ability to plug in 3 hard drives to my router and the are accessible to me at 5gb through my lan and also makes them sharable on the network

But I have an Apple USB 3.0 Smart Drive, an external USB 3.0 1TB back up HDD (with its own external power), and a USB 2.0 mouse connected to the Anker

I plugged in a USB powered external hard drive (the only device in the hub) and my Mac continued to see the device cycle through a connected/disconnected state

This lets me hook up my USB speakers, external hard drive and use ethernet rather than rely on WiFi

I haven't stressed it by maxing out the network channel while moving large amounts of data via other USB data devices (ext hard drives, thumbdrives, etc), but I haven't had any issues which is exactly what you'd expect out of a piece of hardware like this

I have an external hard drive with video footage that I edit

My hard drives kept getting kicked offline and my router went haywire after connecting the ethernet connection

The only issue I've encountered is sometimes when I plug in a new thumb-drive/hard-drive while one is already plugged in, it will temporarily detach/disconnect the one already plugged in to load the drivers of the new device

this is a limited / lower POWER hub probably cannot support ANYTHING (without dropouts) in addition to a single USB hard drive, according to the Anker written instructions.

I moved a 4.11GB movie file from my laptop to an external USB 3.0 hard drive connected to the Anker hub in 38.25 seconds

But it works as expected, external drive powered well and reliably

Unfortunately though, my computer doesn't have enough USB drives for all of that

Only one hard drive was detected using the hub and no other peripherals were detected

The replacement adapter appears to work properly now during backup of laptop harddrive to NAS...with the original adapter the backup of the 50GB hard drive would fail 3 out of 4 times as stated above

Also, be aware that when using this with a Surface Pro 3, it definitely does the job, but you will only be using low power usb3 devices in it (mouse, keyboard, flash drive) and not powering external hard drives, etc

These external hard drives flicker on and off, and can not keep an continuous power source

The Ethernet port does a great job of downloading or uploading to a network hard drive

I was able to add wired ethernet and the external camera (Logitech c920) through this hub, and just for my own curiosity, I also hooked up my external hard drive that is powered via USB and it all worked perfectly!

So I could move the recordings from the recorder to my computer without unplugging the hard drive from the recorder and plug it into my computer

So, currently it seems to me that this is a fine USB hub for lower power items such as plugging in a mouse, a speaker set, and a thumb drive all together at once, OR a single solo larger usb portable drive (with none of the other items plugged in), and for occasional use of the ethernet jack with no other devices plugged in.

He needed to connect to the university internet with an ethernet cable and stay connected to his backup hard drive and printer, etc... this seems to do the trick.

Only drawback is whenever I turn my USB speakers on or off, the external hard drive and other USB drives attached disconnect and reconnect.

Anker overnighted me a free replacement and explained that this device does not support connections with big power consumption, such as external hard drives and wireless mouse receivers

The device works perfectly with my external hard drive, wireless mouse, and ethernet connected simultaneously.

, this is a little harder to test, but I did hook up a very fast drive I had sitting around (read speeds of 400MB/s or 3.2Gb/s) and it gave the same performance through the hub as directly connected

The Hub works great and all my drives are accessible guickly.

Those of you plugging hard drives into the usb ether expander will not be able tip get smoothest device to work

I use this with a Henge Docks so that I can use external hard drives and full gigabit ethernet

I've only tested the USB ports with USB 2.0 drives and they work.

And by warm I really mean warm
