High-speed CFexpress Type B card

The Gigaram 64GB CFexpress Type B card delivers read speeds up to 760MB/s and write speeds up to 245MB/s. It uses the PCIe 3.0 interface with NVMe protocol to handle continuous RAW burst shooting and high-bitrate video. This capacity suits professional photographers and videographers who need reliable, fast media for demanding capture workflows.

Thermals noise and power draw

As a solid-state memory card with no moving parts, it operates silently and generates minimal heat during normal use. Power is drawn directly from the host camera or reader through the CFexpress slot, requiring no external supply. The rugged construction is rated magnet-proof, shockproof, static-proof, temperature-resistant, UV-resistant, waterproof and X-ray-proof for field durability.

Upgrade path and when it matters

This card replaces slower XQD or earlier CFexpress media when your camera supports the Type B form factor and NVMe speeds. The jump is worthwhile for shooters who regularly fill buffers during extended bursts or record RAW 4K and Full HD video that demands sustained write performance. It is not suited for devices limited to UHS-I or UHS-II SD slots, nor for cameras that cannot be firmware-updated to recognise CFexpress Type B.

Questions about this item

How do I install this CFexpress Type B card in my camera, and what step is often missed?

Insert the card into the CFexpress Type B slot until it clicks; the step many miss is updating the camera firmware first for XQD backwards-compatibility.

What maintenance or replacement will this 64GB card need later?

No routine maintenance is required; replace the card only if it fails or when you need more capacity than 64GB.

What limit appears first during sustained RAW burst shooting?

The 245MB/s write speed is the first bottleneck during continuous high-bitrate capture.
