SanDisk 64GB Extreme UHS-I microSDXC Memory Card

The SanDisk 64GB Extreme UHS-I microSDXC Memory Card is built for the demands of action cameras, drones and serious smartphone photography — devices that need sustained write performance to capture high-bitrate video and rapid photo bursts without interruption. At up to 160MB/s read and 80MB/s write, it handles 4K UHD recording across compatible devices, clears the V30 minimum write threshold for uninterrupted video capture, and meets the A2 specification for smooth app performance when used as smartphone expandable storage. The card is rated against shock, temperature extremes, water exposure and X-ray scanning — the conditions that cards face in outdoor, travel and field use. RescuePRO Deluxe data recovery software is included as a download, providing a safety net for accidentally deleted files. A full-size SD adapter allows use in cameras and laptops with SD slots. Backed by SanDisk's lifetime limited warranty.160MB/s · V30 · U34K Video · Burst Shooting · Fast Transfer160MB/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 PerformanceFast App Launch · Smooth PerformanceA2 (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 ToughShock · Temp · Water · X-Ray ResistantThe 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 netConsider something else if…✖ You need 128GB, 256GB or larger — see the SanDisk Extreme PRO range✖ You need maximum write speed (200MB/s+) — see SanDisk Extreme PRO✖ You need extended endurance for security cameras — see SanDisk High EnduranceTechnical SpecificationsBrand / ModelSanDisk Extreme microSDXCCapacity64GBRead SpeedUp to 160MB/sWrite SpeedUp to 80MB/sSpeed ClassUHS-I · U3 · V30 · A2 · Class 10Video4K UHD · Full HDProtectionShock · Temperature · Water · X-ray resistantWarrantyLifetime (SanDisk)Box Contents—SanDisk Extreme 64GB microSDXC card—SD adapter (full-size)—RescuePRO Deluxe download codeCompatible With—GoPro action cameras (Hero series)—DJI drones and gimbals—Android smartphones and tablets (microSD slot)—Nintendo Switch—Mirrorless and DSLR cameras with microSD slot—Cameras and laptops with SD slot (via adapter)ConditionBrand New — Retail PackagingWarrantyLifetime SanDiskDelivery4–5 Working Days · Fully TrackedNeed maximum write speed?
