Having a microSD slot is a blessing if you’re a fan of large amounts of storage. Even though phones routinely come with 128GB of storage as a minimum, those who love taking videos and storing local content like movies and music will always appreciate a bit more. This also goes for devices like cameras, laptops (a 128GB ultraportable with a microSD slot is a prime example), and more.
If you want big storage in a tiny package, the SanDisk Ultra 400GB microSD is a great choice to expand your storage on any device. It’s on sale for only $56.99 right now, down from the usual price of $77 (though it often dips below this). This is an all time low for the 400GB version of the card.
If you do pick one up, make sure you device supports it. Smartphones tend to have a microSD storage limit and it may be smaller than 400GB, though this is less of an issue on flagships.
