1 TB microSDXC card for high-speed capture

This SanDisk Extreme PRO microSDXC card offers 1 TB of storage for devices that accept the SDXC format. It is suited to photographers and videographers who need sustained write performance. The A2 rating supports faster app loading on compatible hardware. Buyers who need more capacity must choose a different product.

Japanese-market package with voltage note

The card ships from Japan in packaging intended for that market. Documentation and any on-device language are Japanese and cannot be changed. The supplier notes the product is built for a 100 V electrical standard. Users outside Japan should verify that their card reader and host device supply the correct voltage.

170 MB/s read speed with specific reader

Maximum read speed of 170 MB/s is only achieved with a USB port rated at 170 MB/s or higher and the SanDisk SDDR-B531 card reader. As of 2019/06 this was the only UHS-I reader to reach that figure. Inserting the card into a non-SDXC device will damage data regardless of formatting.
