Q: What do microSD cards do?

The main function of a microSD card is to store digital data, such as photos, videos, music, apps, games, and documents, from small devices like smartphones.

However, they aren’t designed for archiving your data for life and should be thought of more as a tool for transferring files from small to larger devices.

Q: What is the difference between an SD card and a microSD card?

The difference is in the size. A microSD card is basically a miniaturized version of an SD card. An SD card is roughly the size of a postage stamp, while a microSD is around half that size. They both serve the primary function of storing digital data, and both come with various transfer speeds and storage capacities.

MicroSD cards tend to be slightly cheaper than SD cards with the same storage capacity. They are more commonly found in small devices like smartphones and action cameras.

However, microSD cards are usually limited to a 1TB storage capacity. So, devices like high-end DSLR cameras and professional drones will more likely have an SD card slot. But you can still use a microSD card with these devices if you use an adapter, but not vice-versa.

Q: How long does a microSD card last?

MicroSD cards are designed to last up to 10 years, but there are several factors that can shorten this lifespan.

The most common is overuse. Frequently writing and deleting data promotes wear and tear on the memory cells. Other factors, such as exposure to extreme temperatures or magnetic fields, can also affect the card’s longevity.

If you primarily use your card for storage, it will likely last longer than if you were to use the same card for continuously overwriting data. Frequent users should replace their microSD every few years, and it is important to regularly back up your data to avoid permanent loss.

Q: How important are the read and write speeds on my microSD card?

If you only need the microSD card for storage, then a basic card with slower read and write speeds is sufficient.

However, if you want to transfer large files quickly or take photos and videos with high resolutions, especially 4K or higher, you will benefit significantly from a microSD card with faster read and write speeds.

If you often use burst shooting when capturing action sequences, it’s beneficial to use a card with a minimum rating of UHS-II to avoid lag and ensure smooth playback. If you store apps and games on your card, you can enjoy a much better performance on a card as fast as this, too.

Q: Does a 2TB microSD card exist?

No, 2TB microSD cards are not yet commercially available. However, keep an eye out because the boundaries of flash memory are constantly being pushed. In fact, the Japanese company Kioxia did announce a 2TB prototype microSD card in late 2022, while there are a small number of cards with storage capacities of 1.5TB, such as the SanDisk 1.5TB Ultra microSDXC.
