The Barnes and Noble Nook Tablet 7 can be picked up for $50 online and at over 600 retail locations in the United States. The device only has 8GB of internal memory, which means you can run out of storage fairly quickly. Luckily, the Nook Tablet 7 runs on Google Android and users can take advantage of using a SD card and taking advantage of adoptable storage.
Adoptable Storage is a feature on Android Marshmallow whereby the SD card can be treated as internal storage. There are tons of places online where you can score a good deal on a 64GB or 128GB SD card to store all of your e-books, PDF Files or Android apps.
Barnes and Noble makes it difficult to initiate the adoptable storage feature. All you need to do is put in your SD card and then access the settings menu. Next you have to select “Storage & USB.” After that, tap the SD card’s name, tap the SD card settings, then select “Format as Internal.” From there simply follow the on-screen prompts and the tablet will format the SD card and treat it as internal storage from that point onward.
It is important to note that once you format your SD card you will no longer be able to plug it into other devices, such as a smartphone. It is basically locked into your Nook Tablet 7 and I advise turning it off completely if you want to remove it sometime in the future.
