Exact scope

OWC Atlas Dual CFexpress + SD only. Do not substitute a similarly named reader, later revision or regional bundle.

Selected media slots and upstream connection only, not the complete device. Alternative card families in one slot are not additional slots. No hardware testing or measured throughput.

Same connector form, different documented roles

USB-C: Integrated USB-C cable — Captive USB-C upstream plug · Secondary USB-C port — Alternate USB-C upstream port

Do not transfer a capability from one location to another merely because the connector outline matches.

Alternate USB C upstream port

Secondary USB-C port

OWC documents a secondary USB-C port for an alternate longer-cable arrangement. This does not establish a downstream expansion port or simultaneous dual-host operation.

Read before using the profile

  • The integrated USB-C cable and secondary USB-C port provide alternative upstream arrangements; this topology is not reduced to one detachable-cable endpoint.
  • Choose the documented upstream arrangement and follow the exact product instructions; no automatic handoff is offered.

Model scope, caveats and source dates

OWC Atlas Dual CFexpress + SD only. Do not substitute a similarly named reader, later revision or regional bundle.

  • The integrated USB-C cable and secondary USB-C port provide alternative upstream arrangements; this topology is not reduced to one detachable-cable endpoint.
  • Choose the documented upstream arrangement and follow the exact product instructions; no automatic handoff is offered.

No automatic USB handoff. Camera direct transfer, USB4 negotiation and alternate or captive upstream topology require a separate documented workflow.
