Transfer speeds are what I was expecting and it supports a USB3 hard drive we well without any additional power

However, there was a WTF moment when transferring files to a network hard drive

I have a two usb port Macbook Pro which I used with an old USB 2 ethernet combo hub, which worked fine except it wouldn't power portable hard drives

You can't plug an external USB hard drive for CD ROMs in it

Over all it works well, but I could not transfer files between two USB 3 hard drives connected to the hub

It works fine, and I use the USB ports for a label printer, an external hard drive, and a USB memory stick without any problem at all.

So, basically it only works for my external hard drives.

I also have an external hard drive connected to one of the USB ports with no issues.

And the USB ports let me plug in a mouse and a hard drive.

It "seems fine" and I had no problems connecting a portable external hard drive to it even when the laptop was running on battery, though I wouldn't try that for too long

This device is good for a system which may only have 1 or 2 USB ports, where you need additional ports for multiple slower devices (e.g., an external hard drive, Ethernet, + a keyboard and mouse), but if you were to do something like connect multiple high bandwidth devices to it at once, e.g., an external hard drive + capture card, then it will likely not handle such a workload

But this is an understood limitation and I have no plans to "max out" the device - a portable hard drive (which typically would have a high current draw) will always be connected directly to the computer using a separate USB port and not through this USB hub

Perfect number of ports, driving keyboard and external hard drive

I got this to use on my MacBook Pro 15 inch and 3 external hard drives.

Tb and a 500GB hard drives attached alongside.

They initially asked me to take off the attached 500GB hard drive and notice if the connections fails...and since the problem remained unresolved they sent me a replacement

I currently have used a USB flash drive, a 1 TB hard drive & and I leave a USB wireless mouse plugged in and it works fine

I plugged in the external drive and the wireless thingy that connects my wireless keyboard/mouse, and the drive worked, but not the keyboard/mouse.

Have also used to plug in my WD external hard drive and that doesn't seem to have any issues.
