Sony 128GB SF-M Tough UHS-II SDXC Memory Card

World's Toughest SD Card for DSLR and 4K Enthusiasts

The Sony SF-M Tough 128GB UHS-II SDXC card targets photographers and videographers who need storage that survives extreme environments. Its one-piece resin-molded construction delivers bending resistance 18 times the conventional SD standard. An IP68 rating certifies dustproof and waterproof protection, surviving submersion at 16.4 feet for 72 hours. The card also withstands drops from 16.4 feet, keeping data safe in rugged terrain or wild waters.

Durability Engineering Changes Shooting Confidence

The mono-structure design eliminates the ribs and write-protect switch found on standard cards, removing common failure points under physical stress. This sealed build allows continuous operation in dust, sand, mud or rain without a protective case. Photographers can swap cards in harsh conditions without exposing contacts to contaminants. The physical toughness translates directly into reliability for field work where a cracked shell or water ingress would otherwise end a session.

128GB Capacity with 277 MB/s Read and 150 MB/s Write

The 128GB volume holds extended bursts of high-resolution stills or lengthy 4K video clips before offloading. Write speeds up to 150 MB/s clear camera buffers quickly during continuous shooting. Read speeds up to 277 MB/s accelerate ingest to editing workstations. Cards needing sustained write rates above 150 MB/s or capacities beyond 128GB will require a different specification.
