Sony MRW-S1 UHS-II SD Card Reader Writer USB 3.0

The Sony MRW-S1 is a pocket-sized UHS-II SD card reader and writer built for photographers and videographers who need to move large files quickly. Using a USB 3.1 interface that is backward compatible with USB 3.0 and 2.0, the MRW-S1 reads and writes data at speeds that surpass most built-in laptop card slots — a meaningful advantage when offloading high-resolution RAW images or 4K video files from a shoot. It supports both UHS-II and UHS-I SD cards, so it works with the latest high-speed media as well as older cards you may already own.

The reader's compact form factor makes it easy to toss into a camera bag, and a built-in cover shields the USB connector from dust and damage when not in use. An activity indicator light lets you know at a glance when data is being transferred, helping you avoid premature card removal. While the MRW-S1 can also accept microSD cards through a full-size SD adapter, that adapter is not included. Its straightforward single-slot design keeps things simple — plug in your SD card, connect to your computer, and start transferring immediately without drivers or software installation.
