The affordable 1066x cards will offer maximum read and write rates of 160 MB/s and 120 MB/s, respectively, compared to 270 MB/s on Lexar's more expensive 1800x lineup.

Lexar is introducing a brand new family of MicroSD cards this week called the 1066x series to accompany the existing 300x, 633x, 667x, 1000x, and 1800x series. These are Class 10 UHS-I MicroSD cards with support for U3, V30 and Application Performance Class 2 (A2) standards optimized for cameras, drones, 4K UHD recording, and Android smartphones.

For those unfamiliar, the series name signifies the maximum sequential read rate as a multiple of the transfer rate of a CD spinning at 1x (0.15 MB/s). A Lexar 667x MicroSD card, for example, offers sequential read rates of up to 100 MB/s (667 x 0.15 MB/s) while a new 1066x MicroSD card can offer read rates of up to 160 MB/s (1066 x 0.15 MB/s). The fastest in Lexar's MicroSD lineup at the moment is the 1800x UHS-II series.

The 1066x series is now available online in 64 GB, 128 GB, and 256 GB capacities for $29, $34, and $59 USD, respectively. Smaller 32 GB and larger 512 GB options are in the works. The smaller 32 GB version, however, is not expected to support 4K UHD video recording or the A2 standard.
