Useful accessories for your Chromebook

Here’s some add-ons that I think you’ll find very useful if you’ve got or are about to buy a Chromebook.

USB 3.0 hub with network connection

This cool add-on gives me 3 extra USB 3.0 ports and a network port.

At work we use USB to network adapters with Surface Pro’s because they don’t have a network port on them. These nifty little adapters allow you to use a USB port to add a network connection to your device.

On Chromebooks these adapters are perfect for large downloads, file transfers like photos and videos and great for streaming. While searching for one I came across the Anker 3 Port USB 3.0 and Ethernet Hub. It not only is a network adapter but also has a USB 3.0 port included in an elegant aluminium package.

I brought this because it’s portable, useful, stylish and universally compatible with all my devices. In a nutshell it’s an easy way to add a wired network connection and 3 USB 3.0 ports to my Chromebook.

Compact USB 3.0 Flash Drive


If you start running out of space on your Chromebook a USB 3.0 flash drive is the best option. This Ultra compact drive hardly sticks out of the side of the Chromebook and is available for as little as $10 (£6). Sizes range from 16GB to 128GB.

Once you’ve installed Linux on your Chromebook you’ll be left with about 9GB of usable space on the internal drive. At some point you’ll need more space and this ultra compact USB 3.0 drive is an excellent option.

With this drive you get speeds of up to 150MB/s.

Check out the SanDisk Ultra Fit USB Flash Drive.

Class 10 SD Card

If you prefer to keep your USB 3.0 free, an SD card is a good alternative to using a flash drive.

With a dedicated SD card you can leave it permanently in the slot. SD cards are slower but this Sandisk Extreme one is one of the faster ones.

In my case I already have a class 10 microSD card with adapter that I use, but if you are buying a new one, I would highly recommend the SanDisk Extreme SDHC card. It is capable of speeds of up to 90 MB/s and comes in capacities ranging from 16GB to a massive 256GB.

The class indicates the speed of the card with class 10 being the fastest. So if you’re wondering why SD cards vary so much in price, check the class of the card.

Let me know if there is any tech you would recommend to make your Chromebook better.

    I decided I’ll try Toshiba Chromebook 2 i3-5015U 2.1 GHz CPU with SanDisk Ultra Fit 128GB usb3 drive. Speedup is significant for me and you still can leave it permanently plugged (maybe little inconvenient, if you use an USB 3.0 hub plugged in the only USB 3.0 port).

    Planning to install NixOS on it. Really like the architecture. Let’s see how this whole experiment goes.

      Cool, Toshiba’s new Chromebook (model: CB35-C3350) look’s even better, backlit keyboard and i3 processor – definitely one I would recommend! The Ultrafit thumb drive is a good find, really useful if you want faster USB 3.0 speeds compared to SD cards.

      NixOS? I had never heard of it before now, I’ll put that on my list of Linux distro’s to try out.

      I plan to write a post about the new Chromebook and am still gathering info. I would be grateful if you let me know how your experiment turns out. Thanks Atanas.
