SanDisk Extreme microSDXC 64GB UHS-I 170MB/s Read 80MB/s Write

SanDisk Extreme 64GB microSD

The SanDisk microSD 64GB Extreme card stores high-bitrate video and large app data on phones, action cameras, drones, and dash cams that accept microSDXC media. UHS-I bus support delivers up to 170 MB/s read and 80 MB/s write speeds for fast buffer clearing and quick offloads to backup drives. Sixty-four gigabytes reduces card swaps during long recording sessions in the field.

Application Performance Class A2 rating improves random read and write IOPS compared with A1 cards, which benefits Android devices that run apps from adoptable storage. UHS Speed Class 3 and Video Speed Class V30 guarantee minimum sustained write rates for 4K UHD capture on GoPro, DJI, and similar platforms that enforce speed class checks in firmware.

SanDisk builds this card for outdoor and mobile use. Temperature proof operation spans cold mountain shoots and hot vehicle interiors. Shock, waterproof, and X-ray proof ratings protect data during travel and rough handling in construction and inspection workflows. An SD adapter enables imaging and testing in full-size laptop card readers during fleet rollout.
