World's Fastest SD Card by Sandisk Coming Soon..

Sandisk's latest high-tech memory card, Extreme Pro SDHC/SDXC UHS-II cards, are built to surpass the demands put out by Ultra-High-Definition recording available in some of the newest cameras such as Panasonic GH4.

The card is rated at a UHS-II Speed Class 3 and has a maximum transfer speed of 280MB/s. You will most likely never see that kind of speed in an action, but it's based on standardized rating to make comparison easier.  In either case, this will be world's fastest SD card when it is released in April 2014.

The UHS-II classification actually requires a compatible camera so it's not for everyone who owns a device with a SD card slot.  As of now, the only camera to support it is the powerful little Fujifilm X-T1.

These cards can handle enabled for sustained video capture of 30MB/s, making them suitable for 4K, 3D, and high-bitrate Full HD video capture. SanDisk has also announced a new UHS-II card reader/writer for quick transfers via a USB 3.0 interface that you can grab for $50.

The cards will be available in April. 16 GB in three sized: 16, 32, and 64 GB. It is estimated to cost $119 for 16 GB and $299 for the 64 GB version.

When you look at the cards, you'll notice a new pin layout to support the UHS-II bus interface. While the typical row of SD card pin connections are still present, there is now a second row of pins used exclusively to read and write UHS-II signals. The first row of connectors is still used for normal speed, high speed, and UHS-I signals, meaning the cards are backwards compatible with all SDHC/SDXC host devices, albeit without UHS-II performance.

It's great to see that the storage media are keeping up with the advancement in camera and ever increasing pixels of HD videos.
