Angelbird says that its new CFexpress v4 Type B cards set a new benchmark for stable, high-speed performance.****

Angelbird's media has built [a great reputation over the years](https://www.redsharknews.com/a-closer-look-at-angelbird-cards-and-readers) for reliability and performance, and with its latest [AV PRO SE CFexpress B v4 cards](https://www.angelbird.com/prod/av-pro-se-cfexpress-b-v4-mk2-3513/) it looks to raise the bar even higher.

The cards are built to accelerate workflows with reliable performance across all shooting modes, including 12K+ RAW and beyond. And with capacities up to 4 TB and 3700 MB/s read speeds, these cards offer the sort of versatility and capacity to handle pretty much everything that is thrown at them.

 

## Key features

- Industry-leading CFexpress v4 Type B technology with advanced PCIe 4.0 interface for high-speed recording and rapid offloading
- Built for data-intensive video and high-speed burst photo production in up to 12K+ RAW and beyond
- Angelbird's proprietary Stable Stream uninterrupted write and read performance throughout the entire capacity of the card
- Active thermal protection ensures safe operation in extreme environments and prevents the card from overheating
- Withstand temperatures ranging from -12°C to 72°C (10°F to 162°F)

- Backwards compatible with all camera models using CFexpress Type B memory card format, including off-market and legacy models
- In-house data recovery service on hard- and software level
- 3-year limited warranty

While the max read speeds are the same across the range, there are a few performance differences between the cards, speeds basically ramping up with the larger capacities.

“Our goal was clear: unmatched performance, seamless compatibility, and highest reliability – built for today's production demands and future-ready for tomorrow's challenges," comments Roman Rabitsch, Founder & CEO. Job done, so it would seem
