A technician is installing replacement solid-state storage into a desktop system. The motherboard technical manual specifies that M.2 Slot 1 is M-key only and connected directly to four PCIe 4.0 lanes, while M.2 Slot 2 is B-key only and wired through the SATA controller and two PCIe 3.0 lanes. Which of the following statements correctly describe the compatibility and performance characteristics of these slots? (Select TWO.)
- An M.2 NVMe SSD with a single M-key notch can be installed in Slot 1, but it will be physically blocked from fully inserting into Slot 2.Cevap
- An M.2 SATA SSD installed in Slot 2 will be capped at standard SATA III maximum transfer rates of 6 Gbps despite being in an M.2 form factor.Cevap
- CAn M.2 SATA SSD installed in Slot 1 will automatically upgrade to NVMe throughput speeds because the slot connects directly to PCIe lanes.
- DInstalling an M.2 drive with a dual B&M-key edge connector into Slot 2 guarantees PCIe 3.0 x2 NVMe speed performance.
Cevap
An M.2 NVMe SSD with an M-key notch will physically fit into Slot 1 but not Slot 2, and an M.2 SATA SSD in Slot 2 will remain limited to 6 Gbps SATA III speeds.
Physical M-key drive connectors prevent mechanical insertion into B-key slots. Furthermore, M.2 drives utilizing the SATA protocol remain constrained by SATA III 6 Gbps speed limitations regardless of the M.2 connector interface.
