Capacity and speed ratings

This SanDisk Extreme Pro microSDXC card provides 512GB of storage for devices that accept the microSDXC form factor. It carries UHS-I U3 and Video Class V30 ratings, meaning it sustains at least 30 MB/s sequential write for 4K video capture. The A2 classification indicates improved random read and write performance for app workloads.

UHS-I bus limits

The card operates on the UHS-I interface, so maximum throughput is bound by that single-lane bus. Sequential reads reach 170 MB/s and writes reach 140 MB/s, but real-world transfer rates will not exceed the host controller's UHS-I implementation. Devices limited to slower speed classes will fall back to their own maximums.

microSDXC form factor

The microSDXC physical size fits smartphones, action cameras, drones and handheld consoles with a matching slot. No adapter is included, so full-size SD slots require a separate microSD-to-SD adapter. The card is rated for temperature, water, shock and X-ray resistance per SanDisk's published durability claims.

Questions about this item

Should I choose the 512GB version or a smaller capacity for my camera?

The 512GB capacity stores more 4K footage and high-resolution photos than smaller cards, reducing how often you need to swap media during long shoots.

What does the 170MB/s read speed mean when I transfer files to my laptop?

The 170MB/s read speed lets you offload large batches of photos and video to a computer quickly, cutting wait time compared to slower cards.

How does the UHS-I U3 interface affect real-world write performance?

The UHS-I U3 rating guarantees a minimum sustained write of 30MB/s, so 4K video recording won't drop frames even when the card fills up.
