Lexar brings huge capacity in a tiny size with the Professional 1800x UHS-II 128GB microSDXC card. The 1800x UHS-II cards offer some of the highest read and write speeds among all microSD cards. They are offered in 32, 64 asn 128GB capacities. All three sizes are claimed to offer 270MB/s read speed, but the write speeds vary by size. The 32GB microSDHC card is rated 245MB/s write, the 64GB variant is quoted at 250MB/s write speed and the 128GB card is rated only 110MB/s write speed. The 128GB is tested in this review. It is model LSDMI128CRBNA1800R with UPC 650590191185
The compact microSD size is intented to fit smartphones, tablets, and action cameras. It can also be used in full-size SD slots in cameras and other devices using the included UHS-II microSD to SD adapter. The blazing speeds quoted are for UHS-II, but when used in older UHS-I and standard SD devices the card reverts to lower speed. Also included is the Lexar LRWM05U-7000 microSD UHS-II card reader which fits USB 3.0 ports.
The reverse side of the card shows the layout of pins necessary for UHS-II compatibility. The lower row of contacts must be used to provide the UHS-II interface. Devices that are not UHS-II enabled will use the top row which is limited ot UHS-I speed and below. UHS-I mode is limited to below 104MB/s bus speed.
Lexar Professional 1800x UHS-II cards are backed by a limited lifetime warranty.
In card reader benchmark testing the The Lexar 1800x 128GB microSDXC reached its highest speed in UHS-II card readers. The card measured up to 290.1 MB/s sequential read speed, just slightly above the 270 MB/s claimed by Lexar. Sequential write speed topped out at 211 MB/s, just off the 110 MB/s claim. In UHS-I card readers, the 128GB 1800x card operates in UHS-I mode and reached high marks of 96.6 MB/s sequential read and 69.9 MB/s sequential write. The write speed in particular trailed several of the faster UHS-I cards.
Note: When this UHS-II card was tested in multi-card readers a microSD to SD UHS-II capable adapter was used. Several multi-card readers support UHS-II only in the full-size slot and not the microSD slot. Testing in non-UHS-II microSD slots provides only UHS-I speed.
