SanDisk 64GB Extreme UHS-I microSDXC Memory Card

160MB/s · V30 · U3

4K Video · Burst Shooting · Fast Transfer

160MB/s sequential read moves large video files to a laptop quickly. 80MB/s write sustains 4K UHD recording at 30fps and handles high-speed JPEG burst sequences without the camera stalling mid-shoot. V30 (Video Speed Class 30) guarantees a sustained minimum write speed of 30MB/s — the SD Association’s threshold for reliable 4K UHD video capture. U3 confirms the same minimum for UHS-rated devices. For GoPro users, this matters: GoPro recommends V30 or higher for 4K recording. For drone pilots, sustained write speed directly determines whether 4K footage captures without dropped frames. For smartphone burst shooting, 80MB/s write is fast enough to fire through a long RAW burst sequence without the camera waiting for the buffer to clear.

A2 Performance

Fast App Launch · Smooth Performance

A2 (Application Performance Class 2) requires 4,000 random read IOPS and 2,000 random write IOPS — the random I/O profile that determines how smoothly apps run when installed on a microSD card. For Android users who install apps or move games to expandable storage, A2 means those apps launch and respond without the noticeable lag that lower-rated cards produce. For Nintendo Switch owners, A2 ensures game load times are comparable to internal storage rather than significantly slower. SanDisk’s Memory Zone app can also be used to automatically move apps and media between phone storage and the card to free up internal space.

Built Tough

Shock · Temp · Water · X-Ray Resistant

The SanDisk Extreme is rated against four environmental threats: shock resistance for drops and impacts; temperature resistance across the operating range a card encounters in outdoor use from winter cold to summer heat; waterproof construction for rain, splashes and brief submersion; and X-ray resistance for airport security scanning. These ratings are particularly relevant for action camera and drone use, where the card is frequently exposed to vibration, temperature change and outdoor conditions. RescuePRO Deluxe data recovery software (downloadable) provides file recovery capability for accidentally deleted photos and videos — a practical safety net for field use.

Great choice if you…

✔ Use a GoPro, DJI drone or action camera for 4K recording
✔ Shoot high-speed photo bursts on a smartphone or mirrorless camera
✔ Need 64GB of fast, reliable expandable storage
✔ Use the card outdoors in challenging conditions
✔ Want data recovery software included as a safety net
