The memory card arms race continues to wage a hot war, and the benefit is SD cards are getting faster, sooner. This time around, Sony is claiming the mantle of “world’s fastest” with a new SDXC II card that can read and write at almost 300 megabytes per second.
“Sony is increasing the speed and efficiency of their SD card lineup with the new SF-G Series. As performance demands and file sizes continue to increase, the SF-G Series of SD cards offer enhanced features optimized for professional photographers, DSLR and mirrorless camera users and videographers.” – Sony Press Release
Looking back, it was only 17 years ago that the SD card standard was announced. With a whopping capacity of 1MB, the first SD card storage capability and writing speed has grown exponentially ever since, culminating in the SDXC UHS ultra high speed cards of today.
Before today’s announcement, the king of the hill was SanDisk’s Extreme Pro UHS-11 video card, which was introduced in 2014 and could write at 250 mbps and read at 280 mbps. Other high speed cards include the Lexar Professional 2000x UHS-II U3 and Toshiba Exceria Pro UHS-II U3.
“As the continuous shooting of higher-resolution images and adoption of 4K video with DSLR and mirrorless cameras increases, the inherent need for larger, faster and more dependable cards becomes apparent. A longtime leader at the forefront of professional media, Sony has met these growing demands with the debut of the SF-G Series, which offers industry leading performance.” -Viviano Cantu, Vice President, Product Marketing, Sony Americas Media and Energy Group
Though faster, however, SanDisk still claims the crown for the largest SD card at 1TB. But storage space isn’t everything. Rated with the capability of writing at 299 Mb/S and reading at 300 mbps, the new Sony SD-G SDXC UHS-II video card will certainly make it easier for the next generation of 8K video cameras to record footage. But of course, Sony does provide one caveat … your mileage may vary: “… transfer speeds vary and are dependent on host devices, operating system and usage condition.”
Additionally, Sony has written a special algorithm which contributes to a shorter buffer clearing time which will prevent a drop in speed while writing data, a draw back of shooting high resolution still images in burst mode. If the Sony card can keep up, that could translate to higher burst still ratings, making cameras even more high performing. Naturally, the higher performing your camera is, the more consistent the card will write, in theory.
Cards will be available in 32GB, 64GB and 128GB configurations, and will be compatible with Sony’s SuperSpeed USB 3.1 standard a port memory card reader, which offers cable free PC connections and fast file copy. Max transfer rate on the Sony SD card will be 312 MB/S. The SD-G series also promises to be waterproof, temperature resistant, shockproof and x-ray proof. Sony’s file rescue software is also compatible.
Price is to be determined, but Sony hopes to have the card out on the market by April. For more information on Sony’s SD card lineup, including the SF-G series, click here.
