The SMGB Series complies with UHS Speed Class 3 (U3) for 4K video. It reads up to 95 MB/s and writes up to 90 MB/s (16 GB: Up to 45 MB/s), for UHS-I ultra-high speed. Rugged durability boosts video and photo fun for reliable performance and no frame drops.

UHS-I is an SD bus standard with the maximum data transfer speed of 104 MB/s.*1 High-speed writing lets you take burst shots without dropped frames, and RAW photos with a digital SLR. It also makes it suitable for all types of video shooting -- from the ultimate 4K, to Full-HD and standard video. High-speed reading lets you easily transfer even large amounts of data. UHS-I is ideal for both video and photo enthusiasts.
*1 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 from an electric current.
*If the fuse blows, the data in the SD card will no longer be readable.
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. “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.
The NAND flash memory, where data is stored on an SD card, has an upper limitation on the number of re-writing cycles.
MLC types can be re-written 10 times longer than TLC types can, and also have a lower error rate. MLC types help to save precious memories much longer.
