XQD card interface

XQD is a named memory-card family with a form factor shared by CFexpress Type B; supported formats still require model documentation.

Also called XQD memory card XQD G series

A shared form factor does not approve a replacement card.

Look for

Read the XQD marking and the exact reader and camera descriptions. Keep model-specific firmware notes attached to that model.

Application notes / Camera media / P123

Which evidence is enough for an XQD reader match?

FIELD NOTES 04

Use a named card and reader pairing. Sony explicitly lists XQD G and M series for MRW-G1; the shared Type B form does not create a universal reader rule.

Identify first

Read the part and the device.

Distinguish XQD markings from CFexpress Type B markings before selecting a reader.

Still unresolved

Keep this requirement open.

Support for other card series, brands or reader models is not established here.

Documented support · named example only

Are Sony CFexpress Type B and XQD G/M series listed?

Yes, those card families are explicitly listed for MRW-G1.

Boundary. Only the named reader and card families; not every XQD reader or camera.

Next check. Confirm the exact card series and the reader label.

S495 · C122D (private workspace) · C123C (private workspace)

Before choosing an adapter or reader

  1. Copy the card’s complete series name.
  2. Check the reader’s card support list.
  3. Do not substitute a camera firmware claim for a reader claim.

C123A (private workspace) — Sony G-series examples are explicitly XQD cards using a PCI Express interface.

Identification and explicitly scoped documentation only; not an end-to-end connection approval

S097

C123C (private workspace) — Sony lists XQD G-series and M-series memory cards for the MRW-G1 reader.

Sony MRW-G1 and these named Sony XQD series only; a shared slot outline does not transfer this support to another reader.

S495

C122C (private workspace) — CFA describes CFexpress Type B as using two PCIe lanes and retaining the same dimensions and connector as XQD. It separately makes camera support conditional on implementation or a manufacturer update.

Card Types public text: form-factor footnote and A/B FAQ; no dimensions or speed table transcribed.

Source interpretation is not independent engineering review, hardware testing, wiring advice or a public-release approval.

Visual reference / P123

See the envelope. Confirm the label.

Published card dimensions reveal proportion, not an approved mating drawing. Contact/key geometry is deliberately omitted.

NOMINAL / 01
XQD: original nominal width by height envelope study, 29.6 by 38.5 mm, 3.8 mm nominal depth. Not a contact or key drawing; no host compatibility approval.

Family label to checkXQD

What can be recognized

Matches Type B in stated physical dimensions. An XQD designation and exact camera/reader documentation are necessary.

Compare the three independently named standards in the common-scale envelope study. The two-dimensional proportional outline excludes card corners, ramps, pins and insertion direction.

Still unverified

Shared envelope and connector family with Type B does not establish protocol support, firmware support, reader recognition or recording compatibility.

Never use this outline for trial insertion, mechanical design, repair, wiring or buying a reader.

Source, geometry and image-rights boundaries

First-party reference reading 9 October 2026. This is newly authored original vector artwork derived only from nominal published W/H values. It contains no borrowed logo, product image, copyrighted engineering drawing or detailed contact geometry. Manufacturer dimensions are facts, not image reuse grants. Independent engineering, source-rights and publication approvals are still required.

Before you connect

What to check

  1. Confirm whether the camera lists XQD, CFexpress Type B, or both.
  2. Confirm the reader supported-media list independently.
  3. Keep card capacity and recording-mode requirements in the selection notes.
