Description
The Sony SF-G TOUGH 256GB is the gold standard for professional storage, engineered for mission-critical workflows that demand the absolute highest speeds and maximum physical protection. As the flagship of the TOUGH line, this card is 18 times more bend-resistant than standard SD cards and features a world-first one-piece molded construction without fragile ribs or write-protect switches. With its V90 speed rating, it is specifically designed to handle the massive data rates of 8K video, 4K 120p, and high-speed RAW burst shooting.
Key Features
-
The World’s Toughest Build: A monolithic, resin-molded design that is nearly indestructible. It is bend-proof up to 180N and drop-proof up to 5 meters (16.4 ft).
-
Ultimate Environmental Protection: Rated IP68 waterproof and dustproof, it can survive being submerged in 5 meters of water for up to 72 hours. It is also resistant to X-rays, magnets, static, and UV.
-
Blazing UHS-II Speeds: Delivers industry-leading transfer rates with a maximum read speed of 300 MB/s and a maximum write speed of 299 MB/s.
-
V90 Video Speed Class: Guarantees a minimum sustained write speed of 90 MB/s, making it essential for recording 8K video, high-bitrate 4K XAVC S-I, and high-frame-rate (HFR) footage.
-
Fragile-Free Design: By eliminating the standard connector ribs and the physical write-protect switch, Sony has removed the components most likely to break off and damage your camera’s internal slot.
-
SD Scan Utility Support: Compatible with software that monitors the card’s flash memory health, providing an early warning before the card reaches its write-cycle limit.
-
Fast Buffer Clearing: The 299 MB/s write speed ensures that even the most demanding high-speed continuous shooting bursts are cleared from the camera’s buffer almost instantly.
