Ready for the field

The card survives a drop from 5 metres and 72 hours under water at a depth of 5 metres, and it is 18 times more resistant to bending than the SD standard requires.

Fast buffer clearing

Write speeds of up to 150 MB/s extend bursts of high-resolution photos and shorten the wait while the camera empties its buffer memory.

For UHS-II SD slots

The card reaches full speed in UHS-II slots, for example in the α7 IV, α7R V, α1 II, FX3A or FX30. In a UHS-I slot it reads at up to 95 MB/s.

The card is built for creators who need both speed and reliability. With a capacity of 256 GB and a UHS-II interface, it delivers read speeds of up to 277 MB/s and write speeds of up to 150 MB/s, making it well suited to high-resolution photography, burst shooting and demanding video formats including 4K recording.

In its rugged TOUGH design the card is significantly stronger than standard SD cards and better withstands bending, impact, dust, water and harsh environmental conditions. Its one-piece moulded construction has no fragile parts such as connector ribs or a write-protect switch, improving long-term durability and reliability in professional field use. With an IP68 rating it copes with immersion, dust and harsh outdoor conditions.

The V60 Video Speed Class guarantees a sustained write speed of at least 60 MB/s for high-bitrate video recording. Sony File Rescue software helps recover accidentally deleted or corrupted files, and SD Scan Utility monitors the condition of the card and warns you before it reaches its write cycle limit.
