Delkin Multi-Card CFast 2.0, SD UHS-II, microSD Card Reader Review

Introduction

The Delkin DDREADER-48 is a multi-card reader that uses USB 3.0 and supports the latest generation of high-speed CFast 2.0, Secure Digital UHS-II and microSD cards. In addition to the three card slots, it has a USB 3.0 port on the front to allow other USB devices including flash drives to be attached.

There are two Secure Digital card slots: one for full-size SD cards including UHS-I and UHS-II and a microSD slot that supports UHS-I. The CFast slot supports CFast 1.0/1.1 and CFast 2.0 cards. The main SD slot operates smoothly and cards insert about 3/4-inch deep into the reader leaving about one third of the card still outside the reader. The main SD card slots supports UHS-II but the microSD slot does not. The micro slot is slightly oversize and the card must be level and centered to insert. Once aligned the microSD card inserts securely with ample card remaining outside the reader to faciliate removal. The CFast slot is about 5/8-inch deep.

The case is made from black plastic with a matte finish on the sides and bottom and gloss finish on top. A blue LED on the top of the reader illuminates when a card is inserted into the reader and blinks when a card is accessed. The reader measures about 3 3/4 by 2 1/4 by 3/4 inches. The top of the reader is made from two pieces of plastic. The sides have a slight arch along the center and the two sides not not quite align on reader tested.

The bottom of the reader has feet on the corners to prevent it from sliding. The label states the reader made in Taiwan.

A 3-foot long USB 3.0 cable is included and connects to a USB 3.0 Micro-B port on the back of the reader.

Supported operating systems include Windows XP, Vista, Windows 7, 8 8.1 and Mac OS 9.0 or later. The reader is backed by a five year warranty.
