Lexar Professional 2000x UHS-II U3 64GB Rev E SDXC Memory Card Review

Lexar Professional 2000x UHS-II U3 64GB Rev E SDXC Memory Card

Introduction

The Lexar Professional 2000x UHS-II is a longstanding favorite of photographers and this Rev E card continues the tradition. It provides up to 300MB/s read speed and 260MB/s write speed. The card is compatible with UHS-I and Standard SD but will operate at lower speed. The highest performance is enabled by using a UHS-II enabled device. Lexar 2000x SD cards are available in 32, 64 and 128 GB capacities. The 64GB SDXC card model LSD64GCRBNA2000R Rev E with UPC 650590182046 is tested in this review. The revision number is printed above the UPC bar code. The card was made in Korea.

The UHS-II interface is visible on the back of the card in the form of a second row of contacts. These contacts connect to a corresponding set of pins in UHS-II enabled devices. The interface operates up to 312MB/s bus speed. In devices that do not support UHS-II, the card is backwards compatible and operates at UHS-I speed up to SDR104 mode (104MB/s) and lower speed in older SD devices.

Recommendation

Lexar 2000x UHS-II cards offer some of the highest read and write speeds available in an SD card. The added benefit of a compact UHS-II reader makes this card stand out from the competition. The reader allows anyone to experience the performance of the card, while only those with UHS-II enabled cameras will benefit from the card's full write speed potential. The card supports the fastest UHS-I mode when used in devices that do not support UHS-II, making it a good choice for those attempting to future-proof their memory card investment.
