Professional CFexpress 4.0 Type B card

The Lexar Professional GOLD 128GB CFexpress 4.0 Type B card is a high-performance memory card built for professional photographers and videographers. It uses the PCIe 4.0 interface to deliver fast data transfer rates for demanding creative workflows. The card is designed to handle high-resolution photos and cinema-quality video capture without dropped frames. It operates reliably in extreme environments from -12°C to 72°C.

Sustained write speed of 3000MB/s

The single specification that decides suitability is the sustained write speed of 3000MB/s, which ensures continuous recording of high-bitrate video formats. Maximum read reaches 3600MB/s and maximum write hits 3300MB/s for rapid file offloading. This performance level supports professional cinema cameras that require guaranteed minimum throughput. Cards without this sustained rating risk frame drops during critical shoots.

128GB capacity for mixed workflows

The 128GB capacity provides space for high-resolution photos and shorter video clips, though extended cinema sessions will fill it quickly. Larger capacities from 512GB to 4TB are available in the same series for projects needing more headroom. The card withstands storage temperatures from -25°C to 85°C for safe archiving. Users shooting long-form 8K or RAW video should consider the higher-capacity models.

Questions about this item

How does the 3600 MB/s read speed translate to actual camera performance?

The 3600 MB/s peak read speed lets you offload 128 GB of footage to a CFexpress 4.0 reader in roughly half the time of a 3.0 card, while the 3000 MB/s sustained write keeps high-bitrate 8K or RAW video rolling without dropped frames.

What does the CFexpress 4.0 Type B interface cap in real use?

CFexpress 4.0 Type B runs over PCIe 4.0 x2, so the card tops out at 3600 MB/s read and 3300 MB/s write; your camera or reader must also support PCIe 4.0 to reach those figures.

Will this Type B card fit my camera’s slot?

Yes — the card uses the standard CFexpress Type B form factor, so it slides into any camera or recorder with a Type B slot, including the Canon EOS, Nikon Z, Fujifilm GFX, Panasonic GH, RED V-RAPTOR, Blackmagic Cinema, DJI Ronin and Hasselblad X2D bodies listed.
