UHS-I is an SD care bus standard with a maximum data transfer speed of 104 MB/s.* The high speed writing lets you take burst shots without dropped frames, or RAW photos with a digital SLR smoothly. The high read speed lets you transfer large-sized data quickly and easily. It is suitable for camera and video enthusiasts.
* Speed varies depending on the environment and condition of host devices.
UHS Speed Class 3 (U3) is a new standard that delivers smooth video recording to meet the demands of advanced applications such as 4K and high bit-rate Full HD. It guarantees a constant minimum write speed of 30 MB/s (240 Mbps).*
* Minimum transfer rate is based on our internal testing under the conditions defined by teh SD Association and it may vary depending upon the host device and file size.
All Panasonic SD and microSD cards feature a Tough & Safe design. Their improved construction allows them to be used in harsh conditions because they are Water, Electrostatic, Shock, Magnetic field, Extreme Temperature and X-ray proof. Also, a built-in fuse* operates to prevent the SD card and host devices from being damaged due to unexpected problems such as overheating in the event of an electrical charge.
* The data recorded on the SD card is no longer readable if the fuse is blown.
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 allow a 10x longer archiving life than TLC types, and have a lower error rate. MLC 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.
