Ideal for professional photographers & videographers, the POWER SD card boasts the fastest available speeds and supports data-intensive modes, including 8K video.

UHS-I vs UHS-II

The UHS-I bus interface allows for transfer speeds up to 104 MB/s, while UHS-II boasts significantly higher speeds up to 312 MB/s. This is due to UHS-II cards being designed with two rows of pins, rather than one like UHS-I, which allow for two lanes of data transfer.

Speed Class

Speed Class (Class 2 to 10), UHS Speed Class (U1 or U3) and Video Speed Class (V6 to V90) indicate an SD card's minimum sustained write speed (e.g. 10 MB/s for Class 10 / U1 / V10 | 30 MB/s for U3 / V30 | 90MB/s for V90). Minimum sustained write speed determines which video recording modes the card can safely support.

Maximum Read Speed

The fastest speed that data can be transferred from the card to a computer. The higher the read speed, the less wait time and sooner post-production can begin. High read speed is ideal for photographers and videographers who need to quickly unload large amounts of data and get back to shooting.

Maximum Write Speed

The fastest speed that data can be written to the card. The higher the write speed, the more you can capture in a certain amount of time. High write speed is ideal for photographers and videographers who are shooting in demanding capture modes, such as high-resolution video and RAW burst photography.
