The CompactFlash Association distinguishes the smaller Type A form from Type B.
Claim scope: Identification and explicitly scoped documentation only; not an end-to-end connection approval
Source links: S096 · Evidence trail → (private workspace)
C121B · P121
CFexpress uses PCI Express with NVMe protocols.
Claim scope: Identification and explicitly scoped documentation only; not an end-to-end connection approval
Source links: S096 · Evidence trail → (private workspace)
C121C · P121
CFA describes CFexpress Type A as the smaller A/B form using one PCIe lane. The A/B type letter identifies a form factor; the separately described version-4 marking identifies a specification generation.
Claim scope: Card Types public text: Type A versus Type B and label FAQ; reinspected 2026-10-08 without changing the inherited source record.
Source links: S096 · Evidence trail → (private workspace)
C121D · P121
Sony’s MRW-G2 instructions list Sony CFexpress Type A and the stated Sony SD families, while explicitly withholding a guarantee for every memory-card type. This is named-reader scope, not support for CFexpress Type B or for all cards.
Claim scope: Printed 5-019-283-B1 (1), PDF page 1 English Compatible memory cards.
Source links: S438 · Evidence trail → (private workspace)
C122A · P122
The CompactFlash Association states that Type B and XQD share a form factor and connector, with camera support conditional on implementation.
Claim scope: Identification and explicitly scoped documentation only; not an end-to-end connection approval
Source links: S096 · Evidence trail → (private workspace)
C122B · P122
Sony labels its CEB-G card examples CFexpress Type B with a PCI Express interface.
Claim scope: Identification and explicitly scoped documentation only; not an end-to-end connection approval
Source links: S098 · Evidence trail → (private workspace)
C122C · P122
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.
Claim scope: Card Types public text: form-factor footnote and A/B FAQ; no dimensions or speed table transcribed.
Source links: S096 · Evidence trail → (private workspace)
C122D · P122
Sony lists its CFexpress Type B memory cards for the MRW-G1 reader.
Claim scope: Sony MRW-G1 and the specified Sony card family only. No camera or other reader approval.
Source links: S495 · Evidence trail → (private workspace)
C137A · P137
Sony MRW-G2 documentation lists CFexpress Type A and SD, while MRW-G1 lists CFexpress Type B and selected Sony XQD series.
Claim scope: Exact documented product and family scope; no physical test, exact-card certification or end-to-end approval.
Source links: S105 · S106 · Evidence trail → (private workspace)
C137B · P137
SanDisk ImageMate PRO USB-C lists SD, microSD and CompactFlash; those names must not be collapsed into one card family.
Claim scope: Exact documented product and family scope; no physical test, exact-card certification or end-to-end approval.
Source links: S109 · Evidence trail → (private workspace)
C137C · P137
Sony specifies the MRW-G2 computer interface as SuperSpeed USB 10Gbps (USB 3.2 Gen 2), supplies USB-C–USB-C and USB-C–USB-A cables, and limits its function guarantee to the supplied cable. This interface label is not a measured card-to-computer copy speed.
Claim scope: PDF page 1 English Specifications, connecting instructions and supplied-cable precaution.
Source links: S438 · Evidence trail → (private workspace)
C137D · P137
The RDF8 EN_RDF8_PS_1905 sheet says that UHS-II cards work only at UHS-I speeds in that reader. Reading a card therefore does not establish use of its fastest bus mode.
Claim scope: PDF page 2 Compatibility note; named RDF8 scope, not a rule about all USB readers.
Source links: S440 · Evidence trail → (private workspace)
C137E · P137
Transcend describes RDF8 with a USB 3.1 Gen 1 interface and states that speed varies with host hardware, software, use and storage capacity. No measured read, write or multi-card aggregate rate is adopted here.
Claim scope: PDF page 2 Interface and Performance note; the USB connector subtype is deliberately not assigned in the new device profile.
Source links: S439 · Evidence trail → (private workspace)
C141A · P141
Sony ILCE-7M4 usable-card documentation separates card families from movie recording requirements.
Claim scope: Exact documented product and family scope; no physical test, exact-card certification or end-to-end approval.
Source links: S116 · Evidence trail → (private workspace)
C141B · P141
Canon EOS R5 Mark II specifications distinguish CFexpress Type B Card 1 from SD-family Card 2 and impose additional media requirements.
Claim scope: Exact documented product and family scope; no physical test, exact-card certification or end-to-end approval.
Source links: S120 · Evidence trail → (private workspace)
C141C · P141
CFA defines VPG in terms of minimum sustained write performance for video recording. A card’s peak read figure and a reader’s USB interface label answer different questions.
Claim scope: Public VPG explanation and MRW-G2 interface example; no benchmark or automatic camera qualification.
Source links: S441 · S438 · Evidence trail → (private workspace)
C141D · P141
CFA warns that VPG Profile 5 is not backward compatible with Profile 4: VPG800 or VPG1600 alone does not establish a mode requiring VPG200 or VPG400. Higher-class substitution is described within a profile, and dual-profile certification is a separate condition.
Claim scope: Public FAQ on VPG-5 versus VPG-4 and dual-profile labeling; no individual card certified by this reference.
Source links: S441 · Evidence trail → (private workspace)
C141E · P141
CFA maintains a certified-card register because a displayed VPG logo may be misused. Check the exact card’s certification and the camera mode rather than treating an unfamiliar label or larger number as approval.
Claim scope: VPG-Certified Media Cards section; no named-card database lookup or counterfeit identification performed.
