ARRI 256GB CFast 2.0 Card | ALEXA Mini & AMIRA | 430MB/s Write

Reliable Storage for Professional Cinema Production

Professional cinematographers using ARRI ALEXA Mini and AMIRA cameras face a critical challenge: unreliable storage media can lead to catastrophic data loss, dropped frames, and workflow interruptions during high-stakes productions. Standard memory cards simply cannot handle the demanding data rates required for ARRIRAW and ProRes workflows.

The ARRI 256GB AV Pro AR CFast 2.0 Memory Card resolves these challenges through its exclusive collaboration between ARRI and Angelbird. Designed specifically for the ALEXA Mini and AMIRA cameras, this certified storage solution delivers consistent performance even in challenging filming environments.

1. Which ARRI cameras is this memory card compatible with?

The ARRI 256GB AV Pro AR CFast 2.0 Memory Card is specifically designed for and only compatible with the ARRI ALEXA Mini and AMIRA cameras. It will not work with other ARRI cameras such as the ALEXA ST, SXT(W), or LF. Additionally, standard Angelbird AV Pro CFast 2.0 cards not labeled as ""ARRI Edition"" will not work with ARRI cameras

2. What warranty does this memory card include and how is shipping handled?

This memory card comes with a 3-year limited warranty, but you must register your product on the Angelbird Personal Service Portal within 30 days of purchase to activate the full warranty benefits. The warranty includes individualized customer service, technical support, and free data recovery service provided by Angelbird's tech team in Austria. Shipping is free, and the product is delivered with secure packaging to ensure it arrives in perfect condition

3. How does this ARRI memory card compare to the SanDisk Extreme PRO CFast 2.0 card?

While both cards support professional cinema workflows, the ARRI AV Pro AR is specifically engineered for ALEXA Mini and AMIRA cameras with guaranteed compatibility. The SanDisk Extreme PRO offers similar read/write speeds (525/450 MB/s vs. 550/450 MB/s) and also supports 4K recording. However, the ARRI card features additional protection technologies, improved heat dissipation, and comes with free data recovery service. The SanDisk card is more versatile across different camera brands but lacks the ARRI-specific optimization and certification

4. What are the best practices for maintaining this memory card?

For optimal performance and longevity: (1) Always format the card in your ARRI camera, not on your computer; (2) Never delete individual files directly in-camera as this can lead to file fragmentation; (3) Avoid ejecting the card during data transfer or while the camera is powered on; (4) Store the card in its protective case when not in use; (5) Keep the card away from extreme temperatures and moisture; (6) Consider labeling your cards to prevent mix-ups when using multiple cards during a shoot

5. What makes Angelbird the preferred manufacturer for ARRI's official memory cards?

ARRI partnered with Angelbird specifically because of their expertise in high-performance storage solutions for professional media production. As Roman Rabitsch, Founder & CEO of Angelbird explained, ""ARRI is a huge global player in the camera industry, understandably they want storage media that's compatible with their cameras and its features and leverages cutting-edge technology.""
Angelbird's manufacturing process includes rigorous quality control and testing specifically for cinema workflows, resulting in memory cards with superior heat management, consistent performance, and enhanced reliability compared to consumer-grade alternatives
