Lexar

Lexar LCXEXP4002T-RNENG 2TB CFexpress 4.0 Type B memory card

SKU CH-4DE2-V1MMZ MPN LCXEXP4002T-RNENG

High-speed CFexpress 4.0 Type B card delivering up to 3600MB/s read and 3300MB/s write with 3000MB/s sustained write for 8K RAW video capture

  • Shoot 8K RAW video smoothly with 3000 MB/s sustained write speed
  • Transfer files rapidly at up to 3600 MB/s read speed
  • Capture fast-action bursts reliably at up to 3300 MB/s write speed
  • Accelerate post-production workflow via PCIe 4.0 interface
  • Leverage NVMe protocol for next-generation camera performance

Professional CFexpress 4.0 Type B Card

This 2TB Lexar Gold Series card uses PCIe 4.0 and NVMe to deliver read speeds up to 3600MB/s and write speeds up to 3300MB/s. It targets photographers and videographers capturing high-resolution images or 8K RAW footage who need reliable, high-capacity storage for demanding creative workflows.

Sustained write performance

The card maintains a sustained write speed of 3000MB/s during extended recording sessions. This prevents dropped frames when shooting commercial-quality video continuously, unlike peak-only ratings that drop under thermal load. Consistent throughput keeps the buffer clear for uninterrupted capture.

PCIe 4.0 Type B compatibility

This card requires a host device with a CFexpress 4.0 Type B slot supporting PCIe 4.0 and NVMe protocols. Cameras limited to CFexpress 2.0 or Type A slots cannot use this card, and older readers will not achieve the rated speeds.

Questions about this item

Does the sustained 3000MB/s write speed generate noticeable heat during long 8K RAW sessions?

The card uses PCIe 4.0 and NVMe to maintain 3000MB/s sustained writes; thermal throttling is managed by the host camera body.

What camera firmware or slot is required to use this CFexpress 4.0 Type B card?

A camera with a CFexpress Type B slot supporting PCIe 4.0 is needed; older Type B slots may fall back to lower speeds.

Will this card work at full speed in a camera that only supports CFexpress 2.0?

It is backward compatible with CFexpress 2.0 Type B slots, but read and write speeds will be limited to the 2.0 host capability.
