How to Increase Firestick Storage

By following this guide, you will learn how to increase the storage on your Firestick. These steps can also be carried out on to other Fire TV devices such as Fire Cubes and Fire TVs.

The Amazon Firestick is a popular streaming device that offers excellent value for money and can be jailbroken with minimal effort. It is a perfect choice for anyone looking to cut the cord, regardless of their experience with streaming devices.

However, just like any other streaming device, you must properly maintain your Firestick to avoid running into issues. Running out of storage is one such issue you’d obviously rather avoid. But, if you need more space what you can do? Luckily, it’s entirely possible to add an external USB storage device to your Firestick in order to get more space. Watch the videos for full details or follow the written step-by-step guides below instead.

Why Should You Increase Firestick Storage?

For the average Firestick user, adding any extra storage is generally unnecessary. The Firestick performs well, without any issues, with as many as 20 different applications installed.

However, Firesticks only come with 8GB of storage space*. But, when you consider Amazon’s pre-installed apps and the space the operating system takes up, you’re left with an average of 5.5GB of usable space.

 * The new Fire TV Stick 4K 2nd-generation now comes with 16GB and is the only Firestick with this amount of storage.

Additionally, some users have IPTV applications installed, free streaming apps or games which can take up a lot of space. Especially if those apps are used to record, download or have large game files.

If you constantly run out of space and get a low storage warning, consider increasing your storage. 

Can I Increase Storage on Any Firestick?

Extra storage can be added to any Firestick, Fire Cube or Fire TV that is running software version Fire OS 5 and above. Additional storage can be used and categorised in 3 different ways: 

  1. General storage – used simply as general storage to share and access files
  2. System storage – used to install more apps 
  3. Mixed storage – used as part general storage and part system storage

Depending on which software version your Firestick, Cube or TV is running, this will determine how extra storage is added and what type of storage it can be used for. So, the first step is to find out which Fire OS version your device is running on.

How to Check Fire OS Version

  1. Open your Firestick Settings
  2. Then select My Fire TV
  3. Select About
  4. Then take a look at the right-hand side of the screen for the Software Version

It will either be Fire OS 5, Fire OS 6 or Fire OS 7.

Can I Use Any Type of Storage?

The type of storage you use is down to you, but there are few things you need to consider when choosing your USB storage.

Storage Size

As Fire TV devices are formatted to FAT32, the maximum size of USB storage you can use is 2TB. However, Amazon officially recommends using USB drives that are 128GB or smaller.

Amazon also recommends that high speed USB 3.0 drives are used, even though Fire TV Devices have a 2.0 USB port. This is because USB 3.0 drives tend to have faster read/write speeds and will perform better, even when connected to USB 2.0 ports.

I prefer to use SanDisk or Toshiba branded storage drives as I’ve yet to experience any issues using these brands with any of my Firesticks.

Whatever storage you’re using, it should be formatted to FAT32. If you have a brand-new storage drive that is up to 32GB in size, it should already be formatted to FAT32. If your storage drive is larger than 32GB it’s likely to be formatted to exFAT.

Depending on which Fire OS version you have, this will determine if the USB storage requires formatting to FAT32 manually before it can be used it with your Firestick.

Fire OS 5 and Fire OS 6 – Manual formatting of storage required 
Fire OS 7 – Supports automatic formatting of storage drives (that are not NTFS)

4GB to 32GB
64GB and above
Default format for memory cards and flash drives

How to Manually Format Storage to FAT32

You’ll need a laptop or PC in order to format a USB storage drive. Storage drives that are 32GB or smaller are easy to format with Windows disk management. However, Windows disk management will not allow  formatting of any USB drive above 32GB into FAT32. In this case you will need to install a free piece of software to format the storage.

Extra Equipment Required to Increase Firestick Storage

If you have a Fire TV, there should be a USB port on the back. USB storage can be plugged in without the need for any further equipment.

Firesticks and Fire Cubes do not have USB ports, so you’ll need some sort of connecter to be to attach the USB storage device. In order to do that, you will need an OTG adapter or an OTG cable. Both do exactly the same thing, one is small and compact and the other gives you a little more flexibility.

If your Fire TV Device is connected to the internet via an ethernet cable and you want to remain connected as such, you’ll need to upgrade to a multi USB hub. The Amazon ethernet adapter will not work as there are no additional ports to attach USB storage.

How to Add and Use the Increased Firestick Storage

Once the USB storage has been formatted correctly (if necessary) and attached to your Firestick, the next steps depend on the Fire OS version. 

Firesticks running Fire OS 5 can use additional USB storage as general storage. Carry on reading below for more information for Fire OS 5.

If your Firestick or Fire TV is running Fire OS 6, adding storage to use to install apps to requires manual input of a line of code. Select the link to find out how: Fire OS 6 Instructions.

Adding additional storage to install more apps to is a much simpler process on Firesticks and other Fire TV devices running Fire OS 7. The process is handled automatically by the system without having to enter any line of code. Select the link to find out how: Fire OS 7 Instructions.

Any Firestick or Fire TV device that is running Fire OS 5 is limited to using extra storage as general storage only. This means that it is only possible to attach your USB storage and use it with your Firestick to access files. The USB storage cannot be used to install additional apps to.

Adding general storage can be useful in a number of ways. Access files on a USB drive with your Firestick such as photos or videos. The best way to view files on your USB drive would be to install a media player such as VLC or MX Player.

It is not possible to update Fire OS 5 devices to Fire OS 6 or 7.

Fire OS 6 and Fire OS 7 devices can use attached USB storage as system or mixed storage.

If you’d prefer to upgrade to a Fire OS 6 or Fire OS 7 device, then choose either the Fire TV Stick 4K, Fire TV Cube 2nd Gen, Fire TV Stick Max, Fire TV Stick Lite or Fire TV Stick 3rd Gen.

  1. Tanya – pls forgive the intrusion. Following your video of some time ago I added external storage to my Firestick using your recommended OTC adapter and ScanDisk flash drive. All worked fine, and I was able to download and use several apps that were stored on the flash drive. Recently, my Firestick failed to recognize the flash drive, and the apps on it were not displayed amongst my installed apps. I assumed that the flash drive had somehow failed, and I removed the OTC adapter and flash drive from my Firestick.

    There was one particular app (Cinema HD) that I really like and tried to reinstall on my Firestick. However, it would not install as that app’s name was still contained somewhere in the Firestick, even though the app itself was not there. My question is how do I either delete that name or install the app on my Firestick’s internal storage. Your help will be greatly appreciated. A US Fan.

    • Hi, if you still have the original flash drive, you can try plugging it back in to check if the apps will now recognise it.
      If not, a factory reset will probably be the best option to fix any issues the unexpected removal of the USB caused.

  2. Hi Tanya, I have been following your videos and recommendations. I have a fire tv 4k max running Fire OS attached to my Dell Monitor on my desk. I decided to upgrade the storage with the OTG adapter you suggested and SanDisk 64GB Ultra Fit USB 3.1 Flash Drive formatted in FAT 32 format through AOEMI software. However, I cannot see the USB in the settings menu or file manager app. I also tried all the troubleshooting steps including soft restart and resetting the Firetv stick. But nothing has worked Any solution for it?

    • Hi Tanya yes I can confirm that I want to use it as the mixed storage. Also I can confirm that disk management tool in parallels (VM to run windows on mac) shows me that the pendrive is formatted as FAT32. But I cannot see the pendrive on my firestick. I cannot even see the popup about type of usage of pendrive. Any other solutions I need to try ?
