The 64GB Lexar 1000x UHS-II card is capable of 150MB/s read and 75MB/s write speeds. It uses the UHS-II interface to achieve the high transfer rate. It is backwards compatible in UHS-I devices but will operate at lower speed. Lexar 1000x SD cards are available in 16, 32, 64, 128 and 256GB capacities. The 64GB SDXC card part number LSD64GCRBNA1000 is reviewed here. The Rev C designation is printed on the product package above the UPC label.
The UHS-II interface is made possible through low voltage signaling and uses a second row of pins that are next to the standard SD card interface. UHS-II memory cards can be used in non-UHS-II devices but will revert to UHS-I speed or below. The fastest speed available in UHS-I is mode SDR104 (104MB/s maximum).
The Lexar 1000x UHS-II 64GB Rev C card was benchmarked in various card readers to asses read and write speeds. The 64GB card surpassed its 150MB/s speed rating reaching up to 166.5 MB/s sequential read. The write speed in UHS-II mode reached up to 111.5 MB/s sequential write, which is well above the 75MB/s write speed claimed by Lexar. In UHS-I readers the card operated at up to 93.9 MB/s read and 89.6 MB/s write.

Lexar 1000x UHS-II cards are offered at a competitive price that compares to fast UHS-I cards. Their fast 150MB/s read speed makes them stand out, but their write speed sometimes trails some of the faster UHS-I cards. In certain cameras that support UHS-II but not UHS-I mode SDR104, the Lexar 1000x cards have an advantage. It is recommended for those looking for fast download speed (with a UHS-II card reader) and good, but perhaps not the fastest available, write speed.
