SD versus microSDCompare physical card forms; verify capacity, bus and speed class separately.Full-size SD card form · microSD card form↗SD capacity versus bus interfaceCapacity family and transport technology are different layers.SD capacity classes: SD, SDHC, SDXC and SDUC · UHS-I and UHS-II bus interfaces · SD Express interface overview↗Internal SATA data versus eSATAExternal data cabling does not establish the device power arrangement.SATA 7-pin data connector · eSATA 7-pin data connector↗CompactFlash versus CFastSimilar names refer to different card families.CompactFlash Type I card interface · CFast card interface↗CFexpress Type A versus Type BRecord the type letter and supported reader, not just the family name.CFexpress Type A card interface · CFexpress Type B card interface↗XQD versus CFexpress Type BA shared form factor does not establish device or firmware support.XQD card interface · CFexpress Type B card interface↗8-pin CPU power versus 8-pin PCIe auxiliary powerWhat does the PSU cable and motherboard/GPU manual call this connector? Pin count alone is not enough.8-pin +12 V CPU power connector (EPS12V form) · PCIe 8-pin auxiliary power connector↗Legacy PCIe auxiliary power versus 12VHPWRIs this the older 2x3/2x4 family or the separate 12+4-contact 12VHPWR form?PCIe 6-pin auxiliary power connector · PCIe 8-pin auxiliary power connector · 12VHPWR 16-contact auxiliary power connector↗SATA, Slimline SATA and Micro SATAWhich physical SATA-family variant does the exact device specify?SATA 7-pin data connector · Slimline SATA connector · Micro SATA connector↗Mini-SAS internal SFF-8087 versus Mini-SAS HD SFF-8643Is the internal storage connector legacy Mini-SAS SFF-8087 or Mini-SAS HD SFF-8643? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.Mini-SAS internal SFF-8087 connector · Mini-SAS HD internal SFF-8643 connector↗Mini-SAS external SFF-8088 versus Mini-SAS HD SFF-8644Is the external storage connector SFF-8088 or the higher-density SFF-8644 form? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.Mini-SAS external SFF-8088 connector · Mini-SAS HD external SFF-8644 connector↗OCuLink versus SlimSASWhich compact cabled storage/PCIe connector family is documented by the host and cable? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.OCuLink SFF-8611 / SFF-8612 connector family · SlimSAS connector family↗PCIe 8-pin, 12VHPWR and 12V-2x6 auxiliary powerWhich exact GPU auxiliary-power connector family does the PSU and device documentation require? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.PCIe 8-pin auxiliary power connector · 12VHPWR 16-contact auxiliary power connector · 12V-2x6 16-circuit PCIe power connector↗PCIe x16 card edge versus MCIO cabled interconnectIs the host interface a card-edge slot or an MCIO/SFF-TA-1016 cabled interconnect family? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.PCI Express x16 164-position card-edge connector · MCIO / SFF-TA-1016 connector family↗SFF-TA-1002 1C versus 2C connectorsIs the documented SFF-TA-1002 variation 1C/56-contact or 2C/84-contact? Contact count distinguishes these forms but does not establish device protocol or host support.SFF-TA-1002 1C 56-contact connector · SFF-TA-1002 2C 84-contact connector↗SFF-TA-1002 4C versus 4C+ connectorsIs the documented variation 4C/140-contact or 4C+/168-contact? The family label alone is not enough to establish the exact connector or implementation.SFF-TA-1002 4C 140-contact connector · SFF-TA-1002 4C+ 168-contact connector↗PCIe x1 versus x4 card-edge connectorsIs the slot/form the 36-position x1 or 64-position x4 mechanical variant? Mechanical width does not establish PCIe generation or active lanes.PCI Express x1 36-position card-edge connector · PCI Express x4 64-position card-edge connector↗PCIe x8 versus x16 card-edge connectorsIs the card-edge form x8/98-position or x16/164-position? Mechanical form does not establish generation, lane wiring or platform support.PCI Express x8 98-position card-edge connector · PCI Express x16 164-position card-edge connector↗Mini PCI Express/mSATA versus M.2Is the host using the older 52-position Mini PCIe/mSATA connector family or an M.2 keyed card-edge form? Similar internal-card roles do not make them physically or electrically interchangeable.Mini PCI Express / mSATA 52-position socket · M.2 card edge interface↗SATA data vs SATA powerSATA data and SATA power are separate connectors with different roles and contact counts. Sharing the SATA name does not make them substitutes.SATA 7-pin data connector · SATA 15-pin power connector↗Mini-SAS HD vs SlimSASMini-SAS HD and SlimSAS are different internal high-density connector families. Match the named SFF form and system documentation, not the general SAS label.Mini-SAS HD internal SFF-8643 connector · SlimSAS connector family↗Mini-SAS HD vs OCuLinkMini-SAS HD and OCuLink are different connector families used in high-speed internal links. Physical resemblance is not evidence of mating or protocol compatibility.Mini-SAS HD internal SFF-8643 connector · OCuLink SFF-8611 / SFF-8612 connector family↗M.2 card edge vs SATA data connectorM.2 is a keyed module interface, not another name for the seven-pin SATA data connector. An M.2 module may use SATA, but its exact host support and physical connection still differ.M.2 card edge interface · SATA 7-pin data connector↗M.2 card edge vs PCIe x4 add-in-card edgeSeparate an M.2 module from a PCIe expansion-card edge. A named adapter can connect particular endpoints, but the physical shape does not establish drive protocol, host lanes or boot support.M.2 card edge interface · PCI Express x4 64-position card-edge connector↗CompactFlash versus CFexpress Type BPATA CompactFlash and PCIe/NVMe CFexpress are different card families; a CF reader label is incomplete.CompactFlash Type I card interface · CFexpress Type B card interface↗CFast versus CFexpress Type BSATA CFast is not PCIe/NVMe CFexpress. Check the full card and reader names before checking performance.CFast card interface · CFexpress Type B card interface↗

Discovery is not a compatibility verdict.
These discovery surfaces route and reorganize facts already represented in the atlas. They do not add electrical ratings, universal pinouts, measured tolerances, exact-device support, wiring approval or an end-to-end compatibility result.
