For Android devices come in a wide variety of different capacities, so it is important to know your device’s capacity. A good guideline to follow is to grab an SD card with at least the same capacity or smaller.

If you just want extra storage for your photos or basic work files, then you’ll be fine with a smaller capacity SD Card of 128Gb. If you’re storing hundreds of photos and videos on your Android device or phone, then 256Gb is the minimum I’d recommend you have on hand. Remember, you can always swap out the micro SD for several smaller Micro SD as an alternative method of storing many photos since the higher storage MicroSD’s can get expensive,

This goes for Android as well as any tablet or smartphone device.

Higher Capacity SD Cards are better for storing large amounts of files, or larger sized video and photos. For example, a higher capacity SD card would be used to store an entire music collection or whole video libraries in one location on your device.

In order to find out what size SD Card you would need for an Android device, it is important to know your device’s internal storage. This can be found either in the general settings or within the Settings application on your Android Tablet or SmartPhone.
