With the new MRW-S3 multifunction USB-C hub, Sonys is targeting professional photographers and videographers because it combines several functions in one device that are useful for these applications, e.g. on a notebook. The hub, which is housed in a robust aluminium housing and weighs only 95 grams, is connected via USB-C to a computer via USB 3.1 Gen 2 and adds a card reader, HDMI, USB-C and USB-A ports. It can also supply the PC and other connected devices with up to 100W of power.
According to Sony, the Sony MRW-S3 is the world&s fastest USB card reader for UHS-II SD and microSD cards with up to 300 MB/s and supports transfer speeds of up to 1,000 MB/s as a hub, according to Sony. An external monitor can be connected via the HDMI output with a resolution of up to 4K at 30 fps. USB power indicators inform the user whether each port can be supplied with maximum power to avoid sudden disconnections due to insufficient power supply.
