Which interface connects host bus adapters to mass storage devices such as hard drives and optical drives?

• A. PCIe
• B. Serial ATA (SATA)
• C. Small Computer System Interface (SCSI)
• D. USB

Answer: (B)

The interface being described is SATA. It is designed to connect storage devices like hard drives and optical drives directly to the host controller, providing a dedicated point-to-point link for mass storage. SATA uses separate data and power connections and supports features like hot-swapping, and it has become the standard internal interface for most consumer drives due to its speed and simplicity. While PCIe can carry storage data for newer drives (like NVMe) and SCSI or USB have their own roles in other contexts, SATA specifically fits the description of linking a host bus adapter to internal mass storage devices.
