From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Silly question perhaps, but are you sure you're using the correct port on your Linux system? If I plug my external HD into a USB2 port, I'm stuck at 30-40MB/sec, while on a USB3 port I get ~150-180MB/sec. That's proportionally similar to the difference you described so I wonder if that's the culprit.
You can verify this in a few different ways. From Terminal, if you run
lsusb
you'll see a list of all your USB hubs and devices.It should look something like this:
So you can see three hubs, one of which is 2.0 and the other two are 3.0. The HDD is on bus 002, which we can see is a USB 3.0 hub by looking at the description of
Bus 002 Device 001
. That's good.If you see it on a 2.0 bus, or on a bus with many other devices on it, that's bad and you should re-organize your USB devices so your low-speed peripherals (mouse, keyboard, etc.) are on a USB2 bus and only high-speed devices are on the USB3 bus.
You can also consult your motherboard's manual, or just look at the colors of your USB ports. By convention, gray ports are USB 1.0, blue ports are 2.0, and green ports are 3.x.
If you're running KDE, you can also view these details in the GUI with kinfocenter. Not sure what the Gnome equivalent is.
I'm using USB 3 10Gbps on my Linux system. The USB stick is USB 3-1.0 and the Windows PC only has USB 2.0 so it should be the slowest but it's actually several times faster.
