512 GB microSDXC for 4K capture

This SanDisk Extreme card delivers 512 GB of UHS-I storage rated U3, V30 and A2. Read speeds reach 190 MB/s with a compatible reader and QuickFlow technology, while write speeds hit 130 MB/s for continuous 4K and 5K UHD recording. The bundle includes a standard SD adapter for broad device compatibility.

Suited for drones, action cameras and Android phones

The card targets creators who need sustained write performance for high-bitrate video and faster app loading on mobile devices. Its rugged construction resists shock, water, temperature extremes and X-rays, making it reliable in harsh outdoor environments. Buyers who require UHS-II or UHS-III interface speeds for professional cinema workflows should look at higher-tier cards.

190 MB/s read speed with QuickFlow reader

The headline transfer rate of 190 MB/s is only achieved when paired with the SanDisk Professional PRO-READER, sold separately. Without that reader, actual throughput will be lower and depends on the host device's UHS-I implementation. This single specification determines whether the card meets your ingest-speed requirements.
