PCIe 4x CFexpress Type-B Adapter

The Vszerda SA-039-HX connects a CFexpress Type-B memory card to a PCI Express 4.0 x4 slot. It operates at PCIe 4.0 gen4x2 bandwidth to support the CFexpress B specification at full speed. The adapter uses gold-plated connectors and a precision-crafted PCB with differential signal layout. It is built for desktop or workstation mainboards with a compatible x4 slot.

Suits CFexpress Type-B workflows

This card serves photographers and videographers moving data from CFexpress Type-B media directly into a PC. It does not accept XQD cards, so users with that format need a different solution. The adapter adds no controller of its own; it passes the card signals straight to the platform. Builders without a free PCIe x4 slot cannot install it.

PCIe 4.0 gen4x2 bandwidth

The link runs at PCIe 4.0 gen4x2, which is the single spec that determines whether the CFexpress Type-B card can reach its rated transfer rate. Gold-plated contacts and the enhanced differential layout preserve signal integrity at that speed. If the host slot negotiates a lower generation or fewer lanes, the card will throttle to match.

Questions about this item

Does the Vszerda SA-039-HX include a CFexpress Type-B card or must I buy one separately?

The adapter board itself is the only item supplied; a CFexpress Type-B memory card must be purchased separately.

Which PCIe slot width do I need for full CFexpress Type-B speed with the SA-039-HX?

A PCIe 4.0 x4 slot is required to deliver the gen4 x2 bandwidth that the CFexpress B specification supports.

What real-world throughput can I expect once the SA-039-HX is installed in a PCIe 4.0 x4 slot?

The board passes PCIe 4.0 gen4 x2 lanes directly to the CFexpress Type-B card, so sustained transfer rates match the card's own rated speed.
