A system technician is deploying and configuring various storage interfaces and form factors across enterprise servers and desktop workstations. Match each storage interface specification on the left with its corresponding technical characteristic or operational constraint on the right.
- M.2 M-Key (Socket 3) NVMe SSDSupports up to PCIe x4 bandwidth for high-performance storage, physically notched at pins 59–66.
- M.2 B-Key (Socket 2) SATA SSDRestricted to SATA protocol speeds (up to 6 Gbps) or PCIe x2, physically notched at pins 12–19.
- U.2 (SFF-8639) NVMe SSDUses a 2.5-inch drive form factor utilizing 4 PCIe lanes via a backplane connector with integrated power lines.
- eSATA (External SATA) InterfaceProvides 6 Gbps transfer speeds using shielded cables up to 2 meters, but does not supply native power to the drive.
Cevap
M.2 M-Key (Socket 3) NVMe SSD matches with PCIe x4 bandwidth notched at pins 59–66; M.2 B-Key (Socket 2) SATA SSD matches with SATA speeds (up to 6 Gbps) or PCIe x2 notched at pins 12–19; U.2 (SFF-8639) NVMe SSD matches with 2.5-inch form factor using 4 PCIe lanes via integrated backplane connector; eSATA Interface matches with 6 Gbps transfer speeds over shielded cables up to 2 meters without native power supply.
Each storage interface specification is accurately paired with its specific bus protocol, physical form factor, keying pinout, or power delivery capability.
