At Angelbird, we understand that true performance isn’t about maximum speeds — it's about delivering smooth, drop-free results throughout the entire creative process, so we always tend to emphasize the “sustained speed” read and write performances.
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
From production to post-production, Stable Stream™ supports you when it matters most.
The entire Angelbird memory card and SSD series features Stable Stream™ technology and ensures consistent, stable performance throughout the capacity of the card.
