Lexar Professional 1800x UHS-II 64GB microSDXC card offers outstanding speed in a tiny form factor to fit smartphones, tablets, and action cameras. The 64GB card is advertised with up to 270MB/s read and 250 MB/s write speeds. This level of performance requires UHS-II but the card is reverse compatible and can operate in UHS-I and standard SD modes. Lexar 1800x microSD cards range in size from 32, 64 and 128 GB capacities. The 64GB version model LSDMI64GCRBNA1800R with UPC 650590191178 is covered in this review.
The back of the card reverals the UHS-II connections in addition to those found on a traditional microSD card. The second row of contacts provides the high speed interface, while legacy devices that lack the pins necessary to interface the UHS-II bus will be limited to UHS-I speed and below. The Professional 1800x cards are sold with the Lexar LRWM05U-7000 microSD UHS-II card reader as well as a UHS-II compatible microSD to full-size SD adapter. The adapter allows the card to be used in other card readers and devides, and maintains its UHS-II capabilities, which would otherwise not be available using a standard microSD to SD adapter.
Lexar covers their Professional series memory cards with a limited lifetime warranty. The card is marked made in Taiwan.
The Lexar 1800x microSD card was benchmarked in card readers to assess its performance. The highest speed was reached using UHS-II card readers where the 1800x microSD card measured up to 300.5 MB/s sequential read speed which is better than the 270 MB/s claimed by Lexar. Sequential write speed measured 248.3 MB/s, slightly less than the 250 MB/s rating. In UHS-I card readers, the 1800x card reverted to UHS-I mode and was limited to 96.7 MB/s read and 88.1 MB/s write speeds. Still fast, but not quite as fast as the fastest UHS-I microSD cards.
Note: In multi-card readers, this UHS-II microSD card was tested in the incuded microSD to SD UHS-II adapter. Although several multi-card readers support UHS-II, it is only in the full-size slot and not the microSD slot. Testing in non-UHS-II microSD slots provides only UHS-I speed.
