Deep dive

Angelbird Stable Stream™

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.
