Sonnet Technologies SF3 Series CFexpress 2.0 Type B/XQD Thunderbolt 3 Pro Card Reader

SKU CH-RA7W-V1XM7

Reads CFexpress 2.0 Type B and XQD cards at full speed via Thunderbolt 3 with dual slots that cut ingest time by up to half

  • Dual-slot design cuts ingest time by up to half
  • PCIe 3.0 x4 Thunderbolt 3 delivers maximum card speeds
  • Forward compatible with Thunderbolt 4 for future connectivity
  • Compact rugged stackable chassis fits any professional setup
  • Backward compatible with Thunderbolt 2 and Thunderbolt 1 Macs

Professional dual-slot ingest

The Sonnet SF3 Series CFexpress 2.0 Type B/XQD Thunderbolt 3 Pro Card Reader is built for photographers and videographers who need to move large volumes of high-resolution stills and 4K 60P RAW footage from memory cards to a workstation. It accepts both CFexpress 2.0 Type B and XQD media in two independent slots so professionals can offload multiple cards without swapping.

Dual-slot throughput with PCIe lanes

Each slot receives two lanes of PCIe 3.0 via the Thunderbolt 3 connection, letting both cards transfer at their maximum supported speeds simultaneously. This architecture cuts total ingest time by up to half compared with single-slot workflows and removes the bottleneck that slows down high-bitrate video offloads.

Rugged stackable chassis with daisy-chain ports

The compact metal enclosure is designed to be stacked or rack-mounted in studio environments. Two Thunderbolt ports provide daisy-chaining for additional peripherals or displays while maintaining full bandwidth to the host. The unit is forward compatible with Thunderbolt 4 hosts and backward compatible with Thunderbolt 2 and Thunderbolt 1 Macs via an adapter.

Questions about this item

Will the dual CFexpress 2.0 Type B and XQD slots need any maintenance or replacement over time?

The card slots are solid-state interfaces with no moving parts, so they do not require scheduled maintenance or replacement under normal use.

What limits sustained transfer speed when ingesting from both cards at once?

Each slot receives two lanes of PCIe 3.0 bandwidth, so the combined throughput ceiling is set by that lane allocation.

How much noise, heat or power draw should I expect when the reader runs all day?

The unit has no fan and draws power from the Thunderbolt bus, so it operates silently with minimal heat during continuous operation.
