What this card is for

The SanDisk Extreme PRO microSDXC 64GB card is built for action cameras, drones and Android devices that need reliable 4K UHD video capture. Its A2 rating means apps launch and run smoothly on handheld consoles or phones. The bundled adapter lets you use it in full-size SD slots.

UHS-I interface limits

The card uses the UHS-I bus, so maximum read speed is capped at 200MB/s and write speed at 90MB/s on this model. Higher speeds quoted for larger capacities require a different bus and do not apply to the 64GB version. Devices without UHS-I support will fall back to lower speeds.

Capacity and headroom

At 64GB you can store several hours of 4K footage or thousands of high-resolution photos before offloading. The V30 and U3 ratings guarantee sustained write performance for continuous recording. Users shooting 5K video or long 4K sessions will fill the card quickly and should plan for frequent offloads or a higher-capacity card.

Questions about this item

Which capacity should I pick for 4K UHD video and app-heavy Android use?

The 64GB model supports 4K UHD recording and A2 app performance; choose it if you want Extreme PRO durability in a single card, or step up to a larger capacity if you need more total recording time.

What does the 200MB/s read speed mean when the card is in my camera or phone?

It is the maximum sequential read speed achievable with a compatible UHS-I reader using SanDisk QuickFlow technology; real-world offload speeds depend on your device and file sizes.

What does the UHS-I interface actually cap in practice?

The card runs on the UHS-I bus with U3 and V30 ratings, guaranteeing a minimum 30MB/s sustained write for 4K UHD video while delivering up to 200MB/s read and 90MB/s write on supported hosts.
