Panasonic Announces SDXC/SDHC UHS-I Memory Cards
Compliant with UHS Speed Class 3 for Reliable 4K Video Recording
Featuring Maximum Read Speed 95MB/s and Maximum Write Speed 90 MB/s

LAS VEGAS, NV (January 5, 2015)  - Panasonic is introducing the new lineup of UHS-I type SDXC/SDHC memory cards by upgrading to the latest “SDUD” that boasts maximum read speed of 95MB/s and maximum write speed of 90MB/s, in addition to compatibility of UHS Speed Class 3 (U3)*1. In addition, the lineup includes a maximum capacity upgraded to from SDXC 64GB to 128GB.

In recent years, the standard of video content has become larger and even consumer products are capable of recording motion picture in 4K.  The footage bitrate is also higher, for products such as the Panasonic Camcorder HC-X1000 and the DMC-GH4 which record full-HD All-Intra at approximately 200Mbps. To make the most of these cutting-edge imaging tools, the recording media also needs to function so there are no dropped frames and all content data is recorded without error. By crystallizing the technology long fostered through the development of digital camcorders and cameras, Panasonic is proud to produce the high quality memory cards that excel not only in the data transfer speed but also in the stability and durability under wide usage conditions to keep the data safe for the long term.

Major Features

1. Ultra High Speed Data Transfer - ideal for 4K video

UHS Speed Class 3 (U3) with minimum write speed of 30MB/s (240Mbps)
The UHS Speed Class 3 (U3) is the latest, highest level of UHS Speed Class at a constant minimum write speed of 30MB/s to ensure smooth recording of high bitrate video.
UHS-I card type with maximum read speed of 95MB/s, maximum write speed of 90MB/s for higher speed data transfer
The UHS-I bus interface enables ultra-high-speed read/write operations. When used with a UHS-I compliant product, the card can have a maximum read speed of 95MB/s and maximum write speed of 90MB/s*1. Users can take advantage of the high read speed for quick transfer of recorded data and high write speed for burst shooting of high resolution still images.


2. Smart Guard – secure data protection


Power Failure Protection
The data will be securely protected even if the recording device has a sudden power failure.
Writing Damage Protection
"Smart Data Writing" technology equalizes the frequency on each writing block in order to reduce defect risk and extend products' lifetime.


3. MLC(Multi Level Cell) – long lasting data preservation


The MLC flash memory stands against repeated writing to achieve long lasting data retention.


4. PROOF 7 – high durability and safety


The Proof 7 boasts water/shock/magnet/X-ray/electrostatic/temperature-proof features and built-in fuse. The memory cards are durable enough to withstand severe field use. The integration of fuse prevents the cards from overheating or igniting even if the card causes mechanical destruction internally.


*1 Under UHS-I bus interface. The speed shown in the table above is not possible with a non-compliant UHS-I device. In that case, high speed mode or default mode is implemented. The actual speed depends on devices and conditions.
*2 Both the Speed Class and UHS Speed Class can only be implemented with Speed Class / UHS Speed Class compliant products.
*3 The SDXC memory card can be used with products that comply with SDXC, and the SDHC memory card can be used with products that comply with both SDHC and SDXC.
