Professional CFexpress Type B cards for filmmakers

This two-pack supplies 128 GB of storage per card for professional filmmakers and content creators who need reliable media for high-resolution workflows. The cards use the CFexpress Type B form factor with a PCI-Express 3.0 bus interface. They are built to handle demanding capture tasks in the field and through post-production.

1900 MB/s read and 1600 MB/s sustained write

Each card delivers maximum read speeds of 1900 MB/s and write speeds up to 1700 MB/s, with minimum sustained write speeds that do not drop below 1600 MB/s. This headroom supports smooth raw 8K, 6K and 4K video recording without frame drops. The VPG-400 rating guarantees a minimum write speed of 400 MB/s for consistent performance.

Dual-card kit frees up workflow bottlenecks

The pair fits into compatible CFexpress Type B slots on cameras and readers, removing the need to offload footage mid-shoot. High sustained throughput reduces buffer clearing time so you can keep rolling. Buyers who need larger capacities or a different form factor such as CFexpress Type A or SD will need to look elsewhere.

Questions about this item

Will these CFexpress Type-B cards work in my older camera that only supports CFexpress Type-A?

No, CFexpress Type-B and Type-A are physically different and not interchangeable; these cards require a Type-B slot.

How can I verify the cards are sustaining the 1600 MB/s write speed during 8K recording?

Use the camera’s built-in write-speed monitor or record a long raw clip and check that the buffer never fills and no dropped-frame warnings appear.

Does the 2-pack include a CFexpress Type-B reader or do I need to buy one separately?

The pack contains only the two 128 GB cards; a compatible CFexpress Type-B reader must be purchased separately.
