Introduction

The Transcend USB 3.0 Card Reader RDF5 is a low-profile card reader. The package claims 90 MB/s read and 60MB/s write (using a Transcend 128GB UHS-I card).

The reader has some side-to-side play when inserted into a USB port. Because the cards are inserted on the side of the reader, inserting and removing cards required extra effort to hold the reader.

The plastic case seems thin and hollow. A cap covers the USB plug gives reader when not in use, but is easily lost of misplaced when removed. A cover is hardly necessary because the card slots are just as prone to debris as the USB plug.

A small blue LED lights when a card is inserted, and flashes when the card is being accessed.

Performance

The RDF5 provided some fast read and write speeds, within a few MB/s of the fastest readers.
