Lexar Professional Dual Slot UHS-II SD/CF Reader Review

Introduction

The Lexar Professional Dual-Slot Reader LRW400U is an update to the Dual-Slot LRW300U CF and SD card reader. It shares the aforementioned pop-up case pattern and adds support for UHS-II SD cards. The reader also supports standard SD, SDHC and SDXC cards including UHS-I and CompactFlash cards up to UDMA 7.

The most notable change is the addition of UHS-Two support which requires an extra row of pins to in the reader to interface boosted contacts of UHS-2 SD cards. As a result SD cards insert slightly over iii/four inches (20mm) into the reader. Compact Flash cards insert to a similar depth. The fit in both slots is precise and cards insert smoothly and seat with a firm and positive feel. A blue LED illuminates when a carte is nowadays and flashes to indicate when a carte du jour is in use. The light on the reader was non every bit bright as the previous model and appeared to be mounted below the window, reducing its visibility.

Externally, the Dual Slot LRW400U is the same as its predecessor. A translucent outer case surrounds the reader and serves to protect the bill of fare slots when the reader is transported. The pinnacle portion of the reader is glossy black plastic. The reader is opened by pressing tabs on the sides of the case. Once pressed, the reader opens quickly and closing is as simple as pushing the reader airtight until it clicks.

The lesser of the reader is covered in a white rubber to forestall the reader from slipping. A label on the bottom shows the part number LRW400U revision A, the serial number and indicates the reader is made in People's republic of china. The back of the reader has a micro USB three port. A 40-inch USB 3.0 cablevision is included with the reader. The reader tin can employ a USB 3.0 connectedness and is backwards compatible with USB two.0.

Performance

The Lexar Dual-Slot Reader was tested with a variery of CompactFlash and Secure Digital cards. The Lexar Professional 2000x UHS-II 64GB SDXC measured 268MB/s sequential read speed and 250MB/s write speed. Using UDMA7 CompactFlash cards such every bit the Lexar Professional person 1066x 128GB, the reader reached over 158MB/s read and 155MB/s write speeds. Results using various cards tin can be viewed in the tabular array below. With UHS-II SD cards the Dual Slot LRW400U was not quite as fast equally the Lexar SR2 UHS-II SD card reader. The CF card write speed improved over the previous Dual Slot reader, upwardly from 139MB/south to over 155MB/s with the new reader.

In the Dual Slot reader both cards can be accessed at the same time, although performance was slightly compromised when reading and/or writing two fast card simultaneously. In the best case the sum of concurrent transfers was just over 200MB/south. Copying from one card to the other measured nearly 90MB/southward when using fast UHS-2 SD and UDMA 7 CF cards.
