A technician is inventorying server and workstation components during a hardware refresh. Match each storage interface or connector type on the left with its correct technical characteristic on the right.
- M.2 M-Key ConnectorUtilizes physical keying at pins 59–66 to support up to four PCIe lanes for high-throughput NVMe SSDs.
- SATA III InterfaceOperates via the AHCI protocol with a maximum theoretical data throughput limit of 6 Gbps.
- U.2 (SFF-8639) InterfaceProvides a 2.5-inch form factor connector routed directly to four PCIe lanes for enterprise NVMe drives.
- M.2 B-Key ConnectorUtilizes physical keying at pins 12��19, restricting PCIe support to a maximum of two lanes.
Answer
M.2 M-Key Connector matches physical keying at pins 59–66 supporting up to four PCIe lanes for NVMe SSDs; SATA III Interface matches operation via AHCI protocol with a 6 Gbps maximum limit; U.2 (SFF-8639) Interface matches 2.5-inch form factor connector routed to four PCIe lanes for enterprise NVMe drives; M.2 B-Key Connector matches physical keying at pins 12–19 restricting PCIe support to two lanes.
Each storage interface correctly pairs with its physical layout, bus limit, or protocol standard. M.2 M-key supports four PCIe lanes for NVMe; SATA III limits throughput to 6 Gbps using AHCI; U.2 provides a 2.5-inch form factor connector with four PCIe lanes for enterprise NVMe; M.2 B-key restricts PCIe connections to two lanes.
