The correct answer is B. NVMe SSD.

According to CompTIA A+ Core 1 220-1201 objectives under Hardware and Storage:

NVMe (Non-Volatile Memory Express) SSDs provide the fastest data access and retrieval speeds compared to other storage types, especially on laptops. NVMe SSDs use the PCIe interface, which allows significantly higher throughput and lower latency than SATA-based storage.

This improves boot times, application load times, and overall system responsiveness.

Why the other options are incorrect:

A . SATA M.2: While faster than traditional 2.5'' SSDs and HDDs, SATA M.2 is limited by the SATA III interface (~600 MB/s), which is slower than NVMe SSDs (~3,000--7,000 MB/s).

C . Optical disk: Optical media (CD/DVD/Blu-ray) is extremely slow and not suitable for quick access or retrieval.

D . 7,200rpm HDD: Mechanical hard drives have the slowest access times and throughput compared to SSDs.
