Frequently asked questions
What is the difference between UHS-I and UHS-II?
UHS-II cards have a second row of pins for faster data transfer, but they require compatible devices. UHS-II cards are backward compatible with UHS-I slots, but they will run at lower speeds. For most users, UHS-I is sufficient.
Can I use a microSD card in a full-size SD slot?
Yes, with an SD adapter. Most microSD cards come with a full-size SD adapter, allowing you to use the card in cameras and laptops that accept standard SD cards.
How do I know if a microSD card is fast enough for 4K video?
Look for cards with a U3 or V30 rating or higher. These cards guarantee a minimum write speed of 30 MB/s, which is required for smooth 4K recording. Some high-end cards offer even faster speeds.
What is the maximum capacity my device supports?
Check your device’s manual or manufacturer’s website. Many modern smartphones and cameras support up to 512GB or 1TB, but older devices may be limited to 32GB or 64GB.
Are expensive cards worth it?
If you record 4K video or need fast transfers, investing in a high-speed card is worth it. For basic storage, a budget card may suffice. Consider your usage patterns.
Can a microSD card be used in a Nintendo Switch?
Yes, the Nintendo Switch supports microSD cards up to 2TB (though 1TB is the largest available). A card with at least U1 speed is recommended for smooth game performance.
How do I format a microSD card?
You can format a microSD card using your device’s formatting tool or a computer. For most devices, FAT32 is used for cards up to 32GB, and exFAT for larger cards. Some devices require FAT32, so check compatibility.
What does A1 or A2 mean?
A1 and A2 are Application Performance Classes, indicating random read/write speeds for app performance. A2 is faster and better for running apps directly from the card, such as on Android devices.
How long do microSD cards last?
MicroSD cards have a limited number of write cycles. For typical use, they can last several years. High-endurance cards are designed for constant recording and last longer in dashcams.
Can I recover data from a corrupted microSD card?
Sometimes data can be recovered using software, but it is not guaranteed. To prevent data loss, regularly back up important files and use quality cards from reputable brands.

For most users, the Samsung EVO Select offers the best balance of price and performance, making it our top recommendation for everyday use. If you record 4K video or use demanding apps, the SanDisk Extreme Pro is the best choice for its speed and durability.
