Difficulty: EasyStorage Devices and Interfaces

A technician is installing an internal SSD into a high-performance video editing workstation. The workstation configuration requires storage read speeds exceeding 3,000 MB/s. Which drive interface and protocol combination must the technician select to meet this throughput requirement?

  1. NVMe over PCIeAnswer
  2. B
    AHCI over SATA III
  3. C
    SATA Revision 2.0
  4. D
    eSATA

Answer

The technician must select NVMe over PCIe to meet the requirement.
NVMe over PCIe is specifically designed for high-performance flash drives and leverages multiple PCIe lanes to easily achieve transfer speeds above 3,000 MB/s.

Step-by-Step Solution

1
Identify the target transfer rate specified in the scenario.
The requirement specifies throughput exceeding 3,000 MB/s.
Establishing the target transfer speed allows filtering out interfaces capped at lower speeds.
2
Compare interface maximum speeds.
SATA interfaces max out at ~600 MB/s, whereas NVMe operating on PCIe lanes can reach multi-gigabyte per second transfer rates.
NVMe over PCIe provides direct connection to CPU/PCIe lanes, overcoming SATA bus bottlenecks.
