UHS-I is an SD bus standard with the maximum data
transfer speed of 104 MB/s.*1 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.
*1 Speed varies depending on the environment and condition of host devices.
UHS Speed Class 3 (U3) is a new speed class standard that delivers smooth video recording to meet the demands of advanced applications like 4K and high-bit-rate Full-HD. Its guaranteed constant minimum write speed of 30 MB/s (240 Mbps) *¹ optimizes the video experience and eliminates dropped frames in both 4K and all-round video.
*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
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 data is stored on an SD, 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.
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.
