Designed for photographers and videographers looking to capture 8K raw footage without dropping frames, the 512GB AV PRO CFexpress 2.0 Type B SE Memory Card from Angelbird provides maximum read speeds of 1785 MB/s and maximum write speeds of 850 MB/s, as well as minimum sustained read speeds of 1785 MB/s and minimum sustained write speeds of 800 MB/s. Thanks to Stable Stream technology, write speeds won't throttle or drop while recording video or shooting continuous image bursts. Furthermore, the Y2 processor drives the power needed to support demanding recording settings and quick data transfers between shooting sessions.
