128 GB CFexpress Type B Card

This SanDisk Extreme PRO card provides 128 GB of storage for cameras that accept the CFexpress Type B form factor. It targets photographers and videographers who need fast media for continuous RAW still bursts or high-bitrate 4K video recording. The card is built for professional workflows where sustained throughput matters more than peak burst figures alone.

Sustained Write Performance for 4K RAW

The card delivers a maximum write speed of 1200 MB/s, with the supplier noting a higher 1400 MB/s figure in additional highlights. These rates are intended to maintain low latency during extended high-speed recording sessions, preventing frame drops when capturing RAW 4K footage. Read speeds reach 1700 MB/s to accelerate offload and post-production ingest times.

CFexpress Type B With Select XQD Backward

The decisive specification is the CFexpress Type B interface, which only fits cameras designed for or updated to support this standard. The card works in select XQD bodies that have received firmware enabling CFexpress operation, but it will not function in older XQD-only cameras without that update. Buyers must verify their camera's compatibility list before purchase.

Questions about this item

Does the CFexpress Type B card generate noticeable heat or draw extra power during continuous RAW 4K recording?

The card is designed for sustained RAW 4K capture with low latency; typical CFexpress Type B cards operate within standard camera power limits and do not require active cooling.

What camera firmware or slot type is required to use this 128GB CFexpress Type B card?

It requires a camera with a CFexpress Type B slot or a select XQD camera that has adopted firmware enabling CFexpress compatibility.

Will this card work at full 1700MB/s read speed in an older XQD body with CFexpress firmware?

The card is backwards-compatible with select XQD cameras that support CFexpress via firmware, but maximum speeds depend on the host camera's interface capability.
