Get up to speed on the latest memory cards fromCFast to CFexpress andmore

Of course, there are things to consider like speed ratings, usually measured in maximum read and write speed. Read speed is about how fast the data on the card can be transferred to a computer. Write speed is how fast the card ingests data from the camera. Sometimes, a single figure is quoted for both values.

oddballs like the expensive Sony SxS, used in the Arri Alexa LF, and Red Mini-Mag SSDs for Red cinema cameras. But with ever-increasing data rates for 4K and above, shrinking cameras and the need for faster transfer with new connections for card readers, there has been a change.
