Where is the SD card slot on a Roku 3?

Hidden slot: find out where the SD card lives on the Roku 3

If, like me, you’re a Roku 3 owner, you might have been nagged to insert an SD card into the device to prevent having to constantly reload channels. And, if you’re like me, you might be wondering where that SD card slot is on the Roku 3, as it’s not immediately obvious.

Where to find the SD card slot on the Roku 3

The back of your Roku 3 will probably look something like this. From this view, it looks like there’s no SD card slot on the device.

However, the Roku 3 hides its SD card slot from view.

If you remove that HDMI cable on the right, you will notice a small slot hiding beneath that, as highlighted below. That’s where you SD card goes.

What type of SD card does the Roku 3 take?

The Roku 3 accepts Micro SD cards.

The company recommends that you use a Class 2 or greater Micro SD card with a minimum of 2GB storage. For best results, I’d go for a Class 10 card. You can get a 32GB one from Amazon for less than £8 at the time of writing.

Why does the Roku 3 need an SD card?

My best guess is the size of the Roku operating system has grown over time, meaning there’s now less space in the internal memory for apps. If you regularly use more than three or four apps on your Roku 3, you’ll find the device has to constantly re-download apps, and that means you have to re-enter login details each time it downloads afresh, which can be a royal pain in the backside with the Roku remote.

If you want to spare yourself from that hassle, pop a Micro SD card into the slot and make the pain go away.
