So much of our content is streamed today rather than downloaded for offline playback, and for a majority of people that means the 16GB of internal storage on the Shield Android TV is actually sufficeint. For those who know from the get-go that they'll need a lot of storage, the Shield Pro with its 500GB hard drive is there for an extra $100 at the start. But most people will want to add storage to their box later, and that's where adoptable storage comes in.
Adoptable storage, which was introduced in Android 6.0 Marshmallow, gives users the power to plug in any storage device over USB and have the system recognize it as a continuous piece of storage indisinguishable from the memory soldered to the board internally. It's a critical feature that so many people can benefit from, and we're going to quickly show you how to use it on the Shield Android TV.
Picking a USB drive to use
Before we get into the step-by-step instructions, I want to make a quick note about what drives you should look to use for adoptable storage. While you can use any drive that connects over USB, there are performance considerations here. A USB 3.0 flash drive is your best bet in terms of performance, value and capacity, and we have a great set of recommendations right here if you don't yet have one.
If you want to go really big, you may be looking at a more traditional external hard drive with a spinning disk inside. These models don't have as quick of random read and write speeds as solid state storage, and you could potentially hit performance bottlenecks — for this reason I still recommend a flash drive or external solid state drive. If you really need more storage, consider an external drive that has a USB 3.0 connection, 7200 rpm disk inside and its own external power source for the best performance.
Setting up adoptable storage
Because data is placed across the internal and external drives under adoptable storage, it's important to know that once you've switched on this setting you can't just remove the drive and use it with another device. In order to do so, you'd have to unmount it from the Shield Android TV and format it to remove all of its data. So before you set up adoptable storage, make sure you're committed to leaving that drive connected to the box for the foreseeable future.
Once you're good to go, this is quick and painless.
- Reminder: All data on your drive will be lost in this process!
- Head into your Shield's Settings
- Navigate to Storage & Reset
- Select the external storage, which will be listed by its name
- Select Erase and format as device storage
- Formatting could take several minutes depending on the size of the drive
After the quick setup process your external drive is now, for all intents and purposes, part of the internal storage of your Shield Android TV. As the system sees fit, data will be placed contiguously across the internal and external storage as if it were one large volume, whether that's apps, media or large games. Keep that drive plugged in, and you'll be a happy camper.

Good article but I have to disagree with one part. I have a 1tb external hard drive that I got for $50 attached to mine. You're not going to get a flash drive at that capacity for that price, so a flash drive isn't necessarily the best bet for value or capacity.
Is 1TB of storage really needed? what do you use it for? Regardless thanks for the additional info.
That really depends on your use case. If you are a user of Plex with DVR 1TB will not last that long. Plus as things continue to get larger it won't take long to burn through 500GB honestly. The biggest counter to that though is the Geforce Now feature that allows streaming of games. In that case how much data is needed. I can't tell you since i haven't used it yet. Live channels and DVR functionality with them is another possible heavy user of storage.
My Shield is set up as a Plex server
Maybe you can put in a good word for me to win the Shield contest...I'd be then happy to provide feedback :)
Copying from an external USB stick to an SD card (with ES File Explorer) is much slower after converting the SD card to adoptable storage. I have a fast SanDisk Extreme 64 GB and while using it as adoptable storage, I have only 3 MB/s in that use-case. My guess is, that writing to adoptable storage in general is not fast (encryption?), but I don't have a good test app to try on the Shield.
My shield won't recognize my USB as adoptable storage so I can't increase memory space to download apps! What am I doing wrong?
