Angelbird Introduces the CFexpress B SE 1TB and CFexpress B SX 330GB Memory Cards

High-end capture memory cards and SSDs are the focus of Austrian firm Angelbird. Both memory cards’ predecessors have been available for one and a half years. However, as cameras record at higher resolutions and frame rates, there is a rising desire for larger cards with more storage space and better performance. Another way to put it is that the craving for speed never disappears.

Although both cards have a reading speed of 1785 MB/s, content producers always seek a sustained high writing speed. For capturing video up to an 8K resolution, Angelbird has advanced the cards’ performance. The new 1TB card can write at a maximum rate of 1550 MB/s and 1300 MB/s continuously. Comparing that to the prior version of the card’s sustained wiring speed of 800 MB/s and a maximum of 850 MB/s, there has been a significant improvement. This implies you might also utilize this card for 12K+ RAW photo shots.

The smaller SX card with 330 GB increases the writing speed much more. It has a maximum speed of 1600 MB/s and a sustained speed of 1480 MB/s! Therefore, your camera has no buffer constraints, and you can shoot photographs up to 12K + RAW. This would make the card perfect for snapping photos at sporting events or of any moving subjects, such as wildlife or fast-moving things.
