128GB CFexpress Type B Card

This 128GB CFexpress Type B card targets photographers and videographers who need fast, reliable storage for modern cameras. It uses the PCIe 3.0 bus to move large files quickly during demanding shoots.

128GB capacity with 1450 MB/s read

The 128GB capacity holds extended bursts of high-resolution stills and long video clips. Sequential read reaches 1450 MB/s while write sustains 490 MB/s, so ingest is swift but continuous high-bitrate recording will hit the write ceiling.

Upgrade from slower XQD or SD media

Replacing older XQD or UHS-II SD cards removes the bottleneck that stalls buffer clearing and limits frame rates. The jump is worth it when your camera supports CFexpress Type B and you regularly shoot fast action or high-bitrate video.

Questions about this item

Will the 128GB CFexpress Type B card operate correctly in my camera that currently uses XQD cards?

The card uses the PCIe 3.0 bus, so it requires a camera with a native CFexpress Type B slot. XQD slots do not support this interface.

How can I confirm the card is delivering the rated 1450 MB/s read and 490 MB/s write speeds after installation?

Run a sustained write test in-camera or with a CFexpress Type B reader on a PCIe 3.0 desktop slot and compare the measured throughput to the 1450 MB/s read and 490 MB/s write figures.

Does the package include a CFexpress Type B card reader or must I purchase one separately?

The box contains only the 128GB CFexpress Type B card itself. A compatible CFexpress Type B reader is not included and must be bought separately.
