SKU CH-GAZQ-WASNS

Two 1 TB CFexpress 4.0 Type-B cards deliver up to 3700 MB/s read and 3500 MB/s write with a minimum sustained write of 1950 MB/s

  • Up to 3700 MB/s read speed via PCIe Gen4
  • Up to 3500 MB/s write speed for high-res capture
  • 1 TB capacity per card in a 2-pack
  • Minimum sustained write 1950 MB/s prevents dropped frames
  • Operates from 32 °F to 113 °F for tough conditions

Professional high-capacity capture

This twin-pack delivers two 1 TB CFexpress 4.0 Type-B cards built for photographers and filmmakers who need sustained throughput for 4K to 12K workflows. Each card offers up to 3700 MB/s read and 3500 MB/s write over a PCIe Gen4 interface, with a guaranteed minimum sustained write of 1950 MB/s and VPG1600 certification to prevent dropped frames during long takes.

Thermal management and power efficiency

Cards operate reliably from 32 °F to 113 °F, and SmartIdle technology automatically shifts the controller into a low-power state whenever the host camera pauses recording. This behaviour reduces internal heat build-up during extended sessions without requiring active cooling or external power considerations.

Workflow acceleration accessories

The bundle includes a licence for RescuePRO Deluxe recovery software, letting you restore accidentally deleted images or clips directly from the media. A compatible CFexpress Type-B reader is not supplied, so buyers must source one separately to realise the rated transfer speeds.

Questions about this item

How do I install the CFexpress 4.0 Type-B card and what step is often missed?

Insert the card firmly into the CFexpress Type-B slot until it clicks; the step people miss is confirming the camera firmware supports CFexpress 4.0 so the PCIe Gen4 link negotiates at full speed.

What maintenance or replacement will the 1TB card need later?

No scheduled maintenance is required; replace the card if sustained write drops below the VPG1600 guarantee of 1600 MB/s or if the card reports media errors during verification.

What limit appears first during sustained 8K recording on the 1TB card?

The minimum sustained write floor of 1950 MB/s is the first hard limit; SmartIdle may also throttle the card if its internal temperature exceeds the 113°F operating ceiling.
