Difficulty: EasyStorage Devices and Interfaces

A technician is installing a standard 2.5-inch internal Solid-State Drive (SSD) into a desktop workstation to replace an older hard disk drive. Which interface uses a compact 7-pin data cable to connect this drive directly to the motherboard?

  1. SATAAnswer
  2. B
    NVMe
  3. C
    eSATA
  4. D
    PCIe

Answer

SATA is the standard internal interface that uses a 7-pin data cable to connect 2.5-inch drives to the motherboard.
The correct answer identifies SATA (Serial ATA), which standardizes internal drive data transfer using a flexible 7-pin cable alongside a separate 15-pin SATA power connector from the power supply.

Step-by-Step Solution

1
Identify the physical form factor and cable requirements for a standard 2.5-inch internal SSD.
Standard 2.5-inch internal drives require a dedicated internal data cable and a separate power connector.
Unlike M.2 drives which slot directly into the motherboard, 2.5-inch drives mount in a drive bay and connect via cabling.
2
Match the pin count (7-pin) to the standard internal storage interface.
The SATA data interface uses a 7-pin keyed connector and cable.
Serial ATA (SATA) specifies a 7-conductor data cable for internal storage communication alongside a 15-pin power connector.
