Know before you buy
The TOUGH series features a one-piece molded design that eliminates the fragile rib structure and write-protect switch found on standard cards. This construction makes it 18 times more bend-resistant and provides a fully sealed, IP68-rated exterior that is impervious to water, dust, and shocks.
This is an SDXC UHS-II card, which is compatible with most modern cameras that accept SD cards. While it is backward compatible with UHS-I devices, you will only achieve the maximum 300 MB/s read and 299 MB/s write speeds when using it in a camera or card reader that supports the UHS-II interface.
Yes, this card is rated V90, which guarantees a minimum sustained write speed of 90 MB/s. This makes it more than capable of handling high-bitrate 4K and 8K video recording without dropping frames.
The card is designed to operate in temperatures ranging from -13°F to 185°F. Its robust, sealed design also protects your data from magnetic interference, X-rays, and accidental drops, making it reliable for challenging outdoor environments.
The TOUGH series removes the physical write-protect switch to improve structural integrity and prevent accidental breakage. You will need to manage write protection settings directly through your camera's menu if your device supports it.
Sony includes a 5-year limited warranty with the SF-G64T. This covers defects in materials and workmanship under normal use, providing peace of mind for professional-grade equipment.
