SanDisk Extreme PRO 64GB microSDXC Memory Card (U3/V30/A2)

High-speed 64GB microSD for 4K cameras, drones and phones

A SanDisk Extreme PRO 64GB microSDXC card built for fast, reliable capture on demanding cameras and phones. It reads at up to 200 MB/s and writes at up to 90 MB/s, so footage and photos move on and off the card quickly.

Tested and formatted before every rental, so it just works on the day.

The SanDisk Extreme PRO is a 64GB microSDXC card on the UHS-I bus, rated Class 10, U3 and V30, with an A2 application performance class. Those ratings matter in the real world.

The V30 rating guarantees a sustained write of at least 30 MB/s, which is the level a camera needs to hold a steady 4K UHD stream without dropping frames, while the U3 and Class 10 marks confirm the same high-speed floor.

Read speeds reach up to 200 MB/s and write speeds up to 90 MB/s, so offloading a full card to a laptop takes minutes rather than a long wait between shots.

The A2 class speeds up random reads and writes, which helps app launches and in-app loading when the card is used as expanded storage in a compatible Android phone or tablet.

It ships in the standard 15 x 11 x 1 mm microSD form factor and comes with a full-size SD adapter, so the same card drops straight into a mirrorless body, DSLR, card reader or laptop that takes a standard SD slot.

Rated to run from -25 C to 85 C and built to be shockproof, waterproof, X-ray proof and temperature proof, it handles outdoor shoots, travel and rugged sets. It suits 4K action cams, drones, phones and pro shoots.
