SanDisk 1TB Extreme PRO SDXC Memory Card for 4K UHD

The SanDisk SD UHS-I memory card is our most powerful one yet, offering read speeds of up to 200MB/s powered by SanDisk QuickFlow Technology. This card is designed to save you time when transferring media, with speeds that go beyond the typical UHS-I 104MB/s. (1)

To achieve maximum speeds, pair the card with the SanDisk Professional PRO-READER SD and microSD (sold separately). The card's shot speeds can reach up to 140MB/s, ensuring you're ready to capture stunning, high-resolution, stutter-free 4K UHD video. (2)

The card's performance is further enhanced by its UHS Speed Class 3 (U3) and Video Speed Class 30 (V30) ratings. The U3 designation indicates that the card is designed to support 4K UHD video recording with enabled UHS host devices, while the V30 rating means it can sustain a video capture rate of 30MB/s, making it suitable for real-time video recording with UHS-enabled hosts.
