Lexar Professional 2000x UHS-II 32GB SD Memory Card Review

Lexar Professional 2000x UHS-II 32GB U3 SDHC Memory Card Front


The Lexar Professional 2000x UHS-II SD card is the fastest SD card offered by Lexar as of early 2015. UHS-II cards feature a new high-speed interface that operates at 312MB/s bus speed. The Lexar card claims a read speed of 300MB/s for the 2000x card. Currently there are only a limited number of digital cameras that support the UHS-II interface: Fujifilm X-T1, Samsung NX1 and Olympus OM-D E-M5 II. UHS-II cards are backwards compatible and operate at UHS-I speed in devices without UHS-II compatibility. In UHS-I mode the Lexar 2000x has a read speed of 95MB/s. The Lexar 2000x cards are available in 32 and 64 GB capacities. The 32GB version is tested here.

To support the new high-speed UHS-II bus, a second row of contacts are located next to the standard SD contacts. These correspond with an extra set of pin in UHS-II compatible devices. A compact UHS-II USB 3.0 SD card reader is included with Lexar 2000x cards.

The Lexar 2000x card was tested in several card readers in addition of digital cameras. In memory card readers the Lexar 2000x came very close to its 300MB/s read rating, reaching 296.5MB/s in the included card reader. It measured an amazing sequential read speed of 272.6 MB/s in the same reader. It performed nearly as well in other UHS-II card readers. In UHS-I readers it is limited to UHS-I speed, but still posted very respectable numbers.

All this performance does come at a cost, but it is currently priced much lower than the SanDisk Extreme Pro UHS-II card and offers superior performance.
