Best Use Cases

  • Professional photographers and videographers: If you use CFexpress 4.0 Type B cards, this reader is essential. It dramatically reduces transfer times for RAW photo sequences and 8K video clips, especially when paired with Lexar's own CFexpress 4.0 cards.
  • On-site preview and delivery: Connect directly to a smartphone or tablet to show clients immediate previews of shots. This is invaluable for event photographers, real estate shooters, or any scenario where quick turnaround is critical.
  • Workflow system builders: As part of the Lexar Workflow ecosystem, you can stack multiple readers and SSDs to ingest from several cards simultaneously. This is ideal for studios and post-production houses handling high volumes of media.
    This reader is overkill if you only use SD cards or if your workflow doesn't require speeds beyond 10Gbps. It's specifically designed for CFexpress 4.0 users who need the fastest possible offload.
