Sony has announced what it is describing as the world´s fastest SD memory cards with the launch of the new SF-G series. The three cards under the new label are capable of reading out at a rate of 300MB/s, but more significantly for camera performance they can accept data at a write speed of up to 299MB/s. Such speeds equip them to receive high resolution video as well as to cope with the new wave of extreme frame rates in DSLR and mirrorless cameras - such as that produced by the Olympus OM-D E-M1 ll.
Sony says that it isn´t just the physical properties of the cards that assist getting long bursts of high resolution images recorded, as the company has also developed a new algorithm that it says `prevents loss of speed in data writing even after repeating burst shooting, and contributes to the camera´s speed of burst shooting´.
Sony will launch three different capacities in the SF-G range; 32GB, 64GB and 128GB, and says the very high read rates possible will reduce the time it takes users to copy large amounts of data from the cards - so long as a suitable card reader is used. Conveniently then, Sony has also announced a new card reader that uses USB 3.1. The MRW-S1 is claimed to be the fastest card reader in the world too, due to its adoption of SuperSpeed USB and a direct, cable-free connection between the reader and the PC´s USB port. No pricing has been released with the news, but the SF-G cards are due to go on sale in March while the card reader is expected for April.
