Product Description
The SanDisk SDDR-399-G46 Extreme PRO SD UHS-II Memory Card Reader is engineered for professionals who require the fastest possible data transfer speeds when working with SD memory cards. This reader utilizes the USB 3.1 Gen 1 interface, which is synonymous with USB 3.0, providing a theoretical maximum throughput of 5 Gigabits per second. This high-speed connection is essential for photographers and videographers who frequently transfer large volumes of high-resolution images and video files, significantly reducing the time spent waiting for data to copy. The primary advantage of this reader is its full support for the UHS-II (Ultra High Speed II) standard. UHS-II technology enables significantly faster performance over UHS-I by incorporating an additional row of pins on the SD card connector. This allows for read and write speeds that can reach several hundred megabytes per second, making it possible to offload entire memory cards in a fraction of the time compared to older card readers. This capability is critical for maintaining efficient workflows, especially when shooting in burst modes or recording high-bitrate video. In addition to its UHS-II capabilities, the SanDisk SDDR-399-G46 is backward compatible with UHS-I and standard SD memory cards, ensuring that it can be used with a wide range of SD media. Its robust design is built to withstand the demands of professional use, whether in a studio or on location. For professionals seeking to optimize their workflow and minimize data transfer bottlenecks, this UHS-II SD card reader offers a reliable and high-performance solution.
