In that time, it's fought off plenty of competition, but still sets the standard when it comes to expandable storage. Nowadays, you'll find SD cards come in all manner of different shapes and sizes, and can be slotted into plenty of devices from cameras and smartphones to handheld games consoles like the Nintendo Switch.

The world of SD cards can be a confusing one, with different speed ratings, sizes and capacities. Buying SD cards can be tricky, but with the right know-how, you'll be able to pick out the right SD card that suits your needs. Here's how to choose an SD card. Shipping with only 32GB of onboard storage, you'll run out of space pretty fast. Unlike most consoles, however, micro SD expansion is on the cards, but which is the best microSD card for your Nintendo Switch?

What with the Nintendo Switch supporting cards up to 2TB, there's plenty of different sizes to choose from. Obviously, prices skyrocket when you're looking at the higher end of the scale, so if you haven't got a whole lot of cash after buying the thing, perhaps get something small - 64GB or similar - for the time being. The biggest thing to look out for is that UHS-1 speed rating.

There are official Nintendo-branded Switch micro SD cards doing the rounds, but they're bloomin' expensive, so here's our pick of the best SD cards for your Nintendo Switch. Here's our top picks!

MicroSD cards, as the name implies, are physically tiny and came about predominantly to be used in smartphones that would benefit from a much smaller card. The next area of confusion is around speed classes. High-resolution and high bit rate video requires a lot of data to be written to the card very quickly.

This stands for Ultra High Speed and refers to minimum sustained writing performance for recording video. UHS came about due to 4K-capable video devices needing faster write speeds. As a rule of thumb, 4K-capable camcorders will usually require at least a U3 rated SD card. It might sound obvious, but the safest way to make sure you buy the correct card is to first consult your product's user guide or specifications, at least to be sure if your device takes full-size SD or microSD cards.

Checking before you buy an SD card is particularly important if your device has specific requirements, such as many 4K camcorders. These will usually explicitly state what type of memory card is required in order to record at the top resolution or bit rate. If you're not recording in 4K, the speed might not be so important. A faster-rated card will still be useful if you're using the card to expand the storage in a smartphone or laptop, as a faster read and write speed will make it more responsive.

Faster cards in a still image camera will also mean being able to take more or faster photos in burst mode, as these can be written to the card far quicker.
