Biwin has introduced the Amber CB500 PRO, a CFexpress 4.0 Type B memory card aimed at professional filmmakers, photographers and other creators working with high-resolution footage and rapid still-image bursts.
The card combines a PCIe 4.0 ×2 interface with quoted sequential speeds of up to 3,750MB/s for reads and 3,500MB/s for writes. Biwin is positioning that performance for data-heavy camera workflows, including 8K and 12K RAW recording, then carrying the same media into faster offloads and post-production.
Built for high-bitrate 8K and 12K capture
High-resolution RAW footage can place sustained pressure on a storage card, not merely demand a short burst of peak speed. Biwin says the CB500 PRO is designed to keep recording stable through long takes, fast action, commercial productions and other scenarios where interrupted capture can mean losing an unrepeatable shot.
The card carries CompactFlash Association Video Performance Guarantee certification. Biwin specifies VPG1600 for all four capacities, indicating a minimum sustained recording speed of 1,600MB/s under the certification conditions. The 160GB, 320GB and 640GB versions are also certified for VPG400, while the 1280GB model is listed with VPG1600 certification.
That certification is the more relevant figure for demanding video work than a headline burst rate alone. It describes a guaranteed performance floor within the VPG test framework, although real-world results still depend on the camera, recording format, firmware, card temperature and the wider workflow.
Up to 3,750MB/s reads and 3,500MB/s writes
Peak performance varies slightly by capacity. Biwin rates the 160GB and 320GB cards for up to 3,700MB/s sequential reads and 3,400MB/s sequential writes. The 640GB and 1280GB versions increase those figures to 3,750MB/s and 3,500MB/s respectively.
Those transfer rates are intended to help beyond capture. Moving large RAW photo sets or high-resolution video from the card to a suitably fast reader and workstation can shorten media offloads, letting crews review footage and begin editing sooner. Reaching the quoted maximums will require compatible CFexpress 4.0 hardware; the slowest link in the camera-to-reader-to-computer chain will set the practical ceiling.
Four capacities for different production scales
The Amber CB500 PRO is available in 160GB, 320GB, 640GB and 1280GB capacities. The smaller cards may suit still photography, shorter shoots or workflows that rotate media frequently, while the two larger options provide more room for extended RAW recording and reduce the need to change cards during a take.
| Capacity | Sequential read, up to | Sequential write, up to | VPG certification |
|---|---|---|---|
| 160GB | 3,700MB/s | 3,400MB/s | VPG400 and VPG1600 |
| 320GB | 3,700MB/s | 3,400MB/s | VPG400 and VPG1600 |
| 640GB | 3,750MB/s | 3,500MB/s | VPG400 and VPG1600 |
| 1280GB | 3,750MB/s | 3,500MB/s | VPG1600 |
Camera compatibility and field durability
Biwin says it has tested the card with professional cameras from Canon, Nikon, Fujifilm, Panasonic and Hasselblad. That is useful breadth, but buyers should still confirm that their exact camera model, firmware and intended recording mode support CFexpress Type B media and the required performance tier.
The 38.5 × 29.6 × 3.8mm card weighs 9.1g. Biwin lists resistance to dust, shock and extreme temperatures, along with write protection. Its specified operating range runs from -25°C to 72°C, while storage temperatures span -40°C to 85°C. The CB500 PRO is covered by a limited lifetime warranty.
Software support and availability
The card is supported by Biwin Intelligence for storage management tasks such as performance checks and firmware updates. Biwin also offers its Data Recovery Tool for Windows and macOS, although recovery software is not a substitute for maintaining multiple verified backups of valuable footage.
Biwin has not announced region-specific pricing in the launch material. Full specifications and future purchasing information are available on the official Amber CB500 PRO product page. The company’s launch announcement provides additional context for its intended professional video and photography workloads.
