Cevap

The M-key standard is specifically designed to support four PCIe lanes for high-speed NVMe storage.
The M-key physical connector layout features a notch at pins 59-66 and is designed to supply four PCIe lanes (PCIe x4) to high-speed NVMe drives.

Adım Adım Çözüm

1
Identify the performance requirement in the scenario.
The technician needs an M.2 keying format capable of utilizing four PCI Express (PCIe x4) lanes for maximum NVMe throughput.
NVMe solid-state drives rely on multiple PCIe lanes to deliver extreme sequential read and write speeds.
2
Evaluate the M.2 pin keying specifications.
M-key drives use pins 59 through 66 notched out and natively support PCIe x4 and SATA protocols.
This physical layout provides enough pins to accommodate four dedicated PCIe lanes.
