UHS-II is an SD bus standard with the maximum data transfer speed of 312MB/s*. The high speed in writing lets you take burst shots without dropped frames, or RAW photos with a digital SLR smoothly. The high read speed lets you transfer even large-sized data quickly and easily. It is suitable for camera and video enthusiasts.
Video Speed Class V90 is a new speed class standard that delivers smooth video recording to meet the high bit-rate of advanced applications like 4K. Its guaranteed constant minimum write speed of 90MB/s (720Mbps)* optimizes the video experience and eliminates dropped frames in both 4K and all-round video.
*This speed performance is achieved under the conditions specified by the SD Association.
All Panasonic SD cards and microSD cards feature the Tough & Safe design. They are accident proof against the 6 harsh conditions of Water, Static Electricity, Shock, Magnetism, Temperature, and X-rays. Also, a built-in-fuse operates to prevent the SD card and your personal host devices from being damaged due to unexpected problems such as overheating in an electric current.
*If the fuse blows, the data in the SD card is no longer readable.
The NAND flash memory, where the data is stored on an SD, has an upper limitation on the number of re-writing cycles. pSLC types can be re-written 60 times longer than TLC types can, and also have a lower error rate. pSLC types help to save precious memories much longer.
Panasonic's "Power Failure Guard" automatically retrieves the affected part to preserve important data, even in the event that data is damaged by a sudden power interruption. This feature is verified by TUV Rheinland tests. "Data Damage Guard" reduces the defect risk and makes the card's operating life longer by equalizing the re-write frequency of each writing sector.
*This function does not guarantee permanent data retention.
