Built for people who shoot more than they can store. Whether it's 4K clips, hundreds of RAW photos, dash cam footage running all day, or a phone that keeps asking you to delete something — this card is sized and rated to keep up. Pick a capacity above, and a full-size SD adapter is included with every single one, no upsell required.

1. Fast enough to save you time. Up to 100MB/s reads and 30MB/s writes, so shifting large video and photo libraries doesn't eat up your afternoon.
2. Apps that open quicker. A2-rated random performance means apps stored on the card launch and respond faster on Android devices.
3. No dropped frames. U3 and V30 both guarantee a minimum sustained write speed, which is what stops 4K and Full HD recordings from stuttering or cutting out.
4. Made to survive daily use. Shock, vibration, magnet and X-ray resistant, rated for continuous operation from -10°C to 80°C.
5. Two cards for the price of one. The bundled full-size adapter lets the same microSD card work in laptops, DSLR bodies and any standard SD reader.

Storage is measured by manufacturers as 1GB = 1,000,000,000 bytes, while devices report capacity in binary, so the figure you see is always slightly below what's printed on the card. A small amount is also reserved for formatting and system files.

Format the card in the device you plan to use before the first recording session, rather than on a computer. Reformat periodically to clear fragmented data and keep speeds consistent. When checking speeds, use a quality card reader — a worn or slow one will underreport actual performance. Keep in mind quoted speeds are maximums measured under test conditions; real-world speed depends on your host device, reader and file type. Older devices may not support SDXC capacities, so check the manual before choosing anything above 32GB.

Why does my device report less storage than the label?

This happens on every memory card — manufacturers count 1GB as 1,000,000,000 bytes while devices count in binary, and some space is reserved for formatting.

Does it work with older phones and cameras?

64GB and above use the SDXC standard, supported by most devices from the last ten years. Very old hardware may not — check your manual to confirm the max supported capacity.

Do I actually need the SD adapter?

Only if your device uses a full-size SD slot, such as a laptop or DSLR. Phones, drones and action cameras take the microSD card directly, no adapter needed.

Can I record 4K continuously without interruption?

Yes — the U3/V30 ratings guarantee a minimum sustained write speed of 30MB/s, which covers continuous 4K recording.
