SanDisk Extreme Pro SD UHS-II Reader Type-C SDDR-409 top

Introduction

Over the past few years SanDisk has released a number of compact SD card readers. As device manufactuers migrate to USB Type-C ports, SanDisk started releasing USB-C equipped card readers. The initial Type-C SanDisk Extreme Pro SD reader was released in 2017, model SDDR-389. That reader had the Type-C connector on the end of an odd flexible stalk. This newer SanDisk Extreme Pro SD UHS-II USB-C Reader model SDDR-409 has a slightly longer, more traditional cable. It features a single, full-size SD memory card slot. The reader supports non-UHS, UHS-I and UHS-II SD cards.

Supported operating systems include Max OS 10.4x+ as well as Windows 8 and newer. The reader supports USB 3.0 and has a USB Type-C connector (USB-C). SanDisk provides a two year warranty. The reader tested is model SDDR-409-G46 with UPC 619659161064. The reader is made in China.

On the outside, the reader has a hard plastic case with brushed metal accent panel on top. A card access light is located the top of the reader at one end of the metal panel. The ends and sides of the reader are high gloss plastic while the top and bottom have a matte appearance. The reader has a stylish curvy design with a sharp, angled end where the SD card is inserted.

The main portion of the card reader measures 2.2 x 1.5 x 0.5 inches (55 x 37 x 12mm) not including the USB cable section. Overall length including the cable is about 5.5 inches (140mm). Unline solid, one-piece card readers, having a short cable helps to avoid blocking crowded USB ports and also protects the reader and device from damage if the reader is bumped.

The SDDR-409 UHS-II reader was tested using verious UHS-I and UHS-II SD cards. The highest benchmarks were 298.3 MB/s sequential read and 264.7 MB/s sequential write.

Using UHS-I cards the reader reached sequential benchmarks of 99.3 MB/s read and 92.1 MB/s write.

Compared to the previous model SDDR-389 reader, the updated version has very similar performance. There were a few cards however that did not work in the new reader.
