Which storage technology uses the PCIe interface to deliver high-speed data transfer for SSDs?

• A. SATA
• B. USB 3.0
• C. SCSI
• D. NVMe

Answer: (D)

High-speed SSDs rely on a fast, direct connection to the processor. NVMe is a protocol designed to run over the PCIe interface, which offers multiple lanes and very low latency. By using PCIe, NVMe can handle thousands of parallel I/O operations and deliver high throughput and low wait times, maximizing SSD performance. SATA is an older interface that uses the AHCI protocol and is limited in bandwidth and parallelism. USB 3.0 provides external connectivity with its own protocol overhead and isn’t the PCIe path. SCSI is a separate storage protocol typically used over SAS or Fibre Channel. NVMe over PCIe specifically targets SSD speed, making it the best fit for high-speed data transfer.
