[Summary] Sony uses a unique firmware and a new algorithm to prevent data from being written at a lower speed. In addition, SF-G series memory cards are also waterproof, shockproof, resistant to high and low temperatures, shock and X-ray resistance. .
Tencent Digital (Bear) If you are a professional photographer who likes to take high-resolution dynamic photos or 4K ultra-high-definition video, then you must know how important a fast enough SD card is. Sony also understands the needs of everyone, and has just launched a new product called the “fastest in the world†SD card: the SF-G series, which hopes to attract professional photographers and professional film makers.
The new SF-G series includes a 32GB SDHC version and a 64GB/128GB SDXC version with maximum write and read speeds of 299MB/s and 300MB/s, respectively. Compared with competitors, including the ExtremePro UHS-II series from SanDisk and the Professional 2000x UHS-II series from Lexar, the maximum write and read speeds are 260MB/s and 300MB/s, respectively. There is an increase in speed. And to put aside such professional products, for the UHS-I SD card that is common to ordinary consumers, the maximum write speed is usually 80MB/s.
“Continually shooting high-resolution photos and 4K ultra-high-definition video with SLR and non-reverse cameras requires a larger capacity and faster reading SD card to make the whole process more reliable.†Romain Rousseau, Marketing Manager, Sony Europe Indicated.
This Sony SF-G series supports the UHS-II standard and can adapt to different platform hardware more quickly. At the same time, in order to adapt to this write speed of up to 299MB/s, Sony also introduced the matching MRW-S1 high-speed card reader, which allows users to transfer files to the computer faster through the USB 3.1 standard.
Sony's ability to achieve write speeds of up to 299MB/s in new products is largely due to the company's unique firmware and new algorithms to prevent slower data writes. Normally a 1-2GB capacity movie file takes only 4-7 seconds to transfer to Cary.
In addition to its impressive speed, the SF-G series memory cards are also waterproof, shockproof, resistant to high and low temperatures, shock and X-ray resistance.
It is reported that the new SF-G series SD card will be officially released in March this year, while the MRW-S1 card reader will be listed in April. Although Sony did not announce specific prices, as the fastest SD card currently on the market, for professional photographers and videographers, the price will naturally not be too low.
