5 top rated Micro SD cards for every need: Australia's top picks!
Micro SD cards are the ubiquitous storage solution for a vast array of devices, from smartphones and action cameras to Nintendo Switches and drones. Their compact size belies their impressive storage capacity, allowing you to capture stunning photos and videos, store countless apps and games, and securely back up important files. Choosing the right Micro SD card can significantly impact performance – faster read/write speeds lead to quicker file transfers and smoother operation, while higher capacities ensure you never have to worry about running out of space. Investing in a quality Micro SD card is an investment in the longevity and usability of your favorite devices.
What to Look For
Storage Capacity
Consider your needs. Casual users might be satisfied with 64GB, while those recording 4K video or storing extensive game libraries will likely need 128GB or 256GB (or higher).
Speed Class
This is crucial for recording video. Look for ratings like Class 10, UHS-I U1, UHS-I U3, or UHS-II. Higher numbers indicate faster write speeds, minimizing lag and ensuring smooth video recording.
Speed Rating (x Rating)
This number (e.g., x60, x90) indicates the minimum write speed in MB/s. A higher x rating is essential for high-resolution video recording. Aim for at least x60 for 1080p and x90 for 4K.
UHS Bus Type
UHS-I is standard and sufficient for most devices. UHS-II offers significantly faster speeds but requires a compatible device to take advantage of them.
Application Class
‘A1’ and ‘A2’ ratings indicate the card's suitability for running apps directly from the card. ‘A2’ offers even faster random read/write speeds than ‘A1’ and is ideal for smartphones and tablets.
Durability & Brand Reputation
Look for cards advertised as “waterproof,” “shockproof,” and “temperature-resistant” if you plan to use them in harsh environments. Choosing a reputable brand often ensures better quality control and reliability.
