With the improvement of digital imaging technology, the corresponding media files are also getting bigger and bigger. To take care of this demand for transmission, Sony introduced a new USB hub model MRW-S3 for professional photographers. The device has the "fastest" UHS-II SD and microSD readers that support transmission speeds up to 300MB / s. For users who often work with RAW photos or 4K movies, this should help.
In addition, the MRW-S3 supports 100 W power and is equipped with USB-C, USB-A and HDMI ports (4K @ 30fps output is available). The device is equipped with a dust and water protection function IP68, and the aluminum body with the so-called Wave design is also more convenient for grasping and reducing scratches.
For release, the MRW-S3 is set to be included this summer with the new SF-M Tough SD card (64GB, 128GB and 256GB), but the specific price has not yet been confirmed.
