Deep dive
Angelbird Stable Stream™
Because, in our humble opinion, that value is the true measure of a card’s performance. It shows how the card can write or read data consistently, not just at the beginning. This is especially important when you’re shooting videos. If there’s a large gap between the minimum and maximum read/write speed, chances are you will see dropped frames, errors, or a big drop-off in the performance quality as you begin shooting or gaming.
That’s why Angelbird's Stable Stream™ was developed — to actively support sustained performance.
What is the Stable Stream™ about?
Stable Stream™ supports uninterrupted read and write performance with high IOPS (Input/Output Operations per Second) and low latency across the entire capacity of the memory card.
Consistency: Maintained performance without drops, even under continuous or heavy workloads.
Efficiency: Optimized workflows that allow creators to focus on their creative work rather than worrying about technical limitations.
Why Stable Stream™ matters for you
Creative professionals need tools they can trust. Stable Stream™ guarantees:
Highest sustained performance recording: Seamless handling of up to 12K RAW, high-speed photography, and extended shoots.
Seamless data transfer: Consistent read and write speeds for efficient post-production workflows.
Thermal stability: Advanced Thermal Management to prevent card from overheating.
Real-world performance you can count on
The entire Angelbird memory card and SSD series features Stable Stream™ technology and ensures consistent, stable performance throughout the capacity of the card.
