Know before you buy
The TOUGH specification means the card is built with a solid, one-piece molded structure that is crush-proof and shock-proof. It is designed to survive drops and heavy pressure that would typically snap or damage standard SD cards.
Sony removed the write-protect switch and the traditional ribs on the back of the card to eliminate common points of failure. By removing these fragile moving parts, the card becomes significantly more resistant to breakage and debris buildup.
Yes, this card is backward compatible with UHS-I devices. However, you will be limited to the maximum transfer speeds supported by your camera's specific card slot.
The SD Scan Utility automatically monitors the health of your card every time you plug it into your computer. It alerts you when the card is nearing its write cycle limit, allowing you to replace it before you experience data loss.
Yes, the IP68 rating means the card is fully protected against dust and can be submerged in water for extended periods. It is an excellent choice for shooting in rain, snow, or near the ocean where moisture is a constant concern.
With a write speed of 150 MB/s, this card is well-suited for high-resolution photography and most 4K video recording formats. It provides the consistent performance needed to prevent dropped frames during high-bitrate capture.
