SanDisk 1TB Extreme UHS-I microSDXC V30 Memory Card

Overview

The SanDisk 1TB Extreme UHS-I microSDXC V30 Memory Card is built for microSD devices such as smartphones, drones, and action cameras that shoot Full HD and 4K video alongside raw and burst photography. With 1TB of storage, it runs on the UHS-I bus and carries a V30 speed class rating alongside the U3 rating, both guaranteeing a minimum write speed of 30 MB/s, while read speeds reach up to 245 MB/s and write speeds climb to 170 MB/s. Application Performance Class 2 (A2) support is also built in for smoother, faster app performance on Android devices, and the card is engineered to withstand water, shock, X-rays, and extreme temperatures for reliable use in the field.

V30 and U3 Speed Class Reliability

Dual V30 and U3 speed class ratings both guarantee a minimum write speed of 30 MB/s, so the card keeps up whichever standard your device checks for. Maximum read speed reaches 245 MB/s and maximum write speed reaches 170 MB/s, giving you quick transfers alongside dependable in-camera recording.

Application Performance Class 2 Support

Application Performance Class 2 (A2) support optimises the card for Android devices, managing random read input-output operations per second (IOPS) so apps open quickly and handle tasks like audio, graphics, saved profiles, and permissions without lag.

Rugged, All-Weather Durability

The card is temperature-proof, humidity-proof, waterproof, shockproof, drop-proof, magnet-proof, X-ray-proof, and wear-out-proof, and operates from -25 to 85°C with storage conditions extending to -40 to 85°C, so it's built to handle the rigours of mobile, drone, and action camera use.

SanDisk Memory Zone App

The free SanDisk Memory Zone app for Android makes it simple to organise, browse, and back up the photos and videos stored on the card, whether you're working from the microSD slot on your phone or a separate card reader.
