Exascend Catalyst SDXC UHS-II V90 Memory Card
The Catalyst SDXC UHS-II V90 is Exascend's high-speed SD card for professional cinematography, rated V90 to guarantee a minimum 90 MB/s sustained write so a shoot never drops a frame or overheats mid-take. It reaches up to 300 MB/s maximum read and 280 MB/s maximum write, fast enough for 8K footage and high-speed burst photography alike.
The card is built for location work: waterproof, dust-resistant, impact-resistant, X-ray-safe, and magnetically shielded, so it survives the trip through airport security as well as the shoot itself. It backs that durability with a generous limited-lifetime warranty and data-recovery support, and is available in 64GB, 128GB, and 256GB capacities.
