Angelbird AV PRO CFexpress A v4 MK3 400 GB

Angelbird AV PRO CFexpress A v4 MK3 Memory card 400 GB

With 400 GB of storage and the CFexpress Type A v4 form factor, this Angelbird AV PRO MK3 fits Sony Alpha and Cinema Line cameras with a CFexpress Type A slot, including the α1 II, α7S III, α9 III, FX3 and FX6. The card has been in-house tested for compatibility with twelve Sony models and delivers the speed that 8K RAW, Sony X-OCN and extended burst sessions demand.

Maximum read speed is 1870 MB/s; maximum write speed is 1160 MB/s. Sustained write speed is 1000 MB/s, which means your camera's buffer won't fill up during a long RAW sequence or continuous 8K recording. Angelbird's Stable Stream technology ensures that performance remains consistent across the full 400 GB, not just at the start of the card. Please note: the 400 GB variant has a lower sustained write speed than the 800 GB and 1600 GB versions. For the longest uninterrupted 8K sessions, a higher-capacity card is recommended.

A built-in temperature sensor and Advanced Thermal Management protect the card from overheating during demanding recording sessions. The power management is designed to be efficient, which benefits your camera's battery life. In the event of data loss or damage, Angelbird offers its own recovery service, carried out in Austria at both hardware and software level. The warranty is three years, activated via angelbird.com/warranty within thirty days of purchase.
