What is expandable memory?

For many phones, the storage onboard is what you get, and that’s it. Phones with expandable memory allow you to add storage if you find you need it in an easy and inexpensive way.

When you’re looking into purchasing a new smartphone, you’ll notice a number in gigabytes listed after the phone model. For example, an iPhone 7 is sold in three variants: 32GB, 128GB and 256GB. That amount of gigabytes (GB) listed refers to the amount of core storage on the device.

As we all take more photos and videos on our smartphones, we tend to fill up that available storage rather quickly, at which point you’ve got to either offload some apps or videos to free up some space.

A phone with expandable storage via microSD cards makes it easy to bump up the storage on your phone via the use of tiny microSD cards.

What is a microSD card?

A microSD card is a tiny fingerprint sized storage device that can be inserted into a smartphone with expandable memory capabilities. Storage sizes can range from 2GB upwards. The current SDXC card format (which not every phone will support) supports a maximum size of a whopping 2TB. Though 2TB are not commercially available yet, they might not be far off. Nintendo's latest console, the Nintendo Switch supports up to 2TB microSDXC.

You can currently purchase 512GB microSD cards, but they’re seriously pricey prospects. Comparatively, a simple 32GB or 64GB card should only cost you in the region of $30-$100.
