C029D · P029
StarTech USB3S2SAT3CB supports 2.5-inch SATA SSD/HDD use and explicitly excludes 3.5-inch hard drives.
Claim scope: Named USB-to-SATA adapter. Do not generalize this product limitation to every powered SATA dock or infer SAS support.
Source links: S492 · Evidence trail → (private workspace)
C030A · P030
M.2 physical fit and keying do not establish whether a host supports a particular SATA, PCIe or NVMe device.
Claim scope: Consumer identification / documented standard or product class only
Source links: S033 · Evidence trail → (private workspace)
C030B · P030
Dell’s version-12 article illustrates 2242 as a nominal 22 × 42 mm module and 2280 as a nominal 22 × 80 mm module. These are module-format examples, not socket mating dimensions.
Claim scope: Article 000144170 version 12, Figure 1 examples (b)–(d); no tolerance, connector geometry or clearance inferred.
Source links: S426 · Evidence trail → (private workspace)
C030C · P030
ATP distinguishes M.2 keying from the interface actually wired to a socket: a mechanically matching key alone does not establish SATA or PCIe support.
Claim scope: Manufacturer compatibility checklist; no universal B, M or B+M key-to-protocol mapping or numeric contact positions.
Source links: S427 · Evidence trail → (private workspace)
C030D · P030
ATP calls for checking module length, mounting position and vertical/component clearance, including single- versus double-sided construction, separately from keying.
Claim scope: Physical fit checklist only; no invented height, tolerance, heat-spreader or fabrication dimensions.
Source links: S427 · Evidence trail → (private workspace)
C030E · P030
ATP separates firmware support for NVMe boot from mechanical fit and advises against treating ordinary M.2 installation as hot-plugging. Follow the exact equipment’s power-off and service instructions.
Claim scope: No claim that every NVMe-capable host can boot every drive; external USB removal is a different operation.

C030F · P030
The ASUS PRIME B550-PLUS AC-HES manual lists M.2_1 with SATA and PCIe x4 modes: PCIe 4.0 for the named Ryzen 5000/3000 desktop families, and PCIe 3.0 for the named 5000 G-Series/4000 G-Series families.
Claim scope: E18712 First Edition, printed vii. Only the manual’s named processor families and M.2_1 slot; actual CPU and firmware still require verification.
Source links: S429 · Evidence trail → (private workspace)
C030G · P030
On the same AC-HES board, the chipset-connected M.2_2 is specified for PCIe 3.0 x4 and SATA; both M.2 slot entries list 2242, 2260, 2280 and 22110 modules.
Claim scope: E18712 printed vii, exact board and slot labels; supported nominal lengths do not establish component clearance or boot qualification.
Source links: S429 · Evidence trail → (private workspace)
C030H · P030
StarTech SM2NGFFMBU33 explicitly excludes M.2 NVMe and AHCI PCI-Express SSDs.
Claim scope: Named SATA-only USB enclosure; the M.2 label or an apparently matching key cannot override this exclusion.

C030J · P030
In TE drawing C-2199230 revision B4, the representative shown as 1-2199230-5 is an M-key board socket; the card edge is its counterpart, not the illustrated component.
Claim scope: V143: the named drawing/revision or exact product page only. Recognition and document-role evidence; not a pinout, adapter verdict, dimensioned mating gauge, electrical approval or current installed-device claim.
Source links: S594 · Evidence trail → (private workspace)
C030K · P030
The C-2199230 part table separates A, B, E and M key variants, and the M-key block includes several part suffixes rather than one universal socket.
Claim scope: V143: the named drawing/revision or exact product page only. Recognition and document-role evidence; not a pinout, adapter verdict, dimensioned mating gauge, electrical approval or current installed-device claim.
Source links: S594 · Evidence trail → (private workspace)
C030L · P030
The C-2199230 drawing specifies 67 contact positions with a key interruption; its two solder-tail rows have different counts, so a single visible row is not the total contact inventory.
Claim scope: V143: the named drawing/revision or exact product page only. Recognition and document-role evidence; not a pinout, adapter verdict, dimensioned mating gauge, electrical approval or current installed-device claim.
Source links: S594 · Evidence trail → (private workspace)
C030M · P030
Kingston states that a PCIe M.2 SSD in a SATA-only host socket—or a SATA M.2 SSD in a PCIe-only socket—does not gain the missing protocol merely from physical fit. Consult the system manual for the exact slot interface and any shared-lane restrictions.
Claim scope: Storage SSD interface only; not a claim about every M.2 socket or PCIe adapter
Source links: S033 · Evidence trail → (private workspace)
C057A · P057
M.2 describes physical form; a compatible shape does not establish SATA, PCIe or NVMe support.
Claim scope: Consumer identification / documented standard or product class only
Source links: S033 · Evidence trail → (private workspace)
C057B · P057
NVM Express’s NVMe over PCIe Transport Specification distinguishes the NVMe host interface from its mapping onto PCIe. Neither the protocol nor the transport name identifies an M.2 mechanical connector.
Claim scope: Revision 1.4, sections 1.1–1.2 and 2, printed pages 6 and 8; no mechanical standard, lane assignment or boot claim.
Source links: S428 · Evidence trail → (private workspace)
C057C · P057
StarTech’s PEX4M2E1 guide requires a PCIe M.2 SSD and an x4-or-larger PCIe expansion slot. Its adapter-driver note does not remove the separate requirement to check the drive’s operating-system compatibility.
Claim scope: Exact PEX4M2E1 page-1 requirements; this does not establish SATA conversion or NVMe boot support.
Source links: S430 · Evidence trail → (private workspace)
C057D · P057
StarTech’s M2-USB-C-NVME-SATA guide lists M.2 PCIe NVMe and M.2 SATA SSD requirements, M-Key/B+M-Key wording and 30/42/60/80 mm lengths for one SSD; the enclosure connects to the host through USB.
Claim scope: Exact enclosure only. Do not infer every key/protocol combination, other enclosure support, achieved transfer speed or permission to insert a bare M.2 drive while powered.

C298A · P298
TE Connectivity product 1759513-1 is described as a 52-position, 0.8 mm centerline board-to-board connector for Mini PCI Express and mSATA.
Claim scope: V50 identification fact only; no wiring, protocol compatibility, installation or fabrication approval is inferred.
Source links: S339 · Evidence trail → (private workspace)
C298B · P298
Molex’s cited Mini PCI Express connector drawing identifies 52 circuits at 0.8 mm pitch and shows odd-numbered positions on one card side and even-numbered positions on the other.
Claim scope: Numbering/orientation context for the cited connector example only; no Mini PCIe or mSATA signal assignment is normalized.
Source links: S358 · Evidence trail → (private workspace)
C298C · P298
Kingston distinguishes M.2 from mSATA: mSATA uses SATA, while M.2 includes SATA and PCIe options and does not use the same physical connector. A shared Mini PCIe/mSATA socket outline still does not establish the host’s wired interface.
Claim scope: Kingston SSD FAQ reinspection on 8 October 2026 plus the existing TE 52-position socket example; inherited source dates unchanged. Not a universal Mini PCIe/mSATA host compatibility result.
Source links: S033 · S339 · Evidence trail → (private workspace)
C298D · P298
TE drawing C-1759513 revision E2 supplies separate Mini PCI Express and mSATA signal-assignment tables for the socket family; one housing does not imply one interface assignment.
Claim scope: V143: the named drawing/revision or exact product page only. Recognition and document-role evidence; not a pinout, adapter verdict, dimensioned mating gauge, electrical approval or current installed-device claim.
Source links: S595 · Evidence trail → (private workspace)
C298E · P298
The socket views in C-1759513 show two contact rows interrupted by an offset key, with short and long contact banks; the study is of the board socket, not a miniature M.2 module.
Claim scope: V143: the named drawing/revision or exact product page only. Recognition and document-role evidence; not a pinout, adapter verdict, dimensioned mating gauge, electrical approval or current installed-device claim.
Source links: S595 · Evidence trail → (private workspace)
C298F · P298
C-1759513 sheet 2 separates half-size and full-size card mounting keepouts, so the socket alone does not describe the complete module-retention arrangement.
Claim scope: V143: the named drawing/revision or exact product page only. Recognition and document-role evidence; not a pinout, adapter verdict, dimensioned mating gauge, electrical approval or current installed-device claim.
