Question
A technician is upgrading a desktop's storage with the fastest option available. The desktop's motherboard is equipped with SATA III, NVMe, and IDE. Which of the following should the technician choose for the best performance?
Options
- APCIe SSD connected via NVMe interface
- B3.5in (8.9cm) 10.000rpm HDD connected via IDE interface
- CM.2 SSD connected via SATA interface
- D2.5in (6.35cm) SSD connected via SATA interface
Explanation
{"question_number": 7, "correct_answer": "A", "explanation": "NVMe (Non-Volatile Memory Express) is a protocol designed specifically for SSDs that communicates directly over the PCIe bus, bypassing the slower AHCI protocol used by SATA. A PCIe SSD using the NVMe interface delivers sequential read speeds of 3,000–7,000+ MB/s, far exceeding SATA III's 600 MB/s ceiling. An M.2 SSD via SATA (C) and a 2.5in SSD via SATA (D) are both limited to ~600 MB/s. An IDE HDD at 10,000 RPM (B) is the slowest option, as IDE tops out at ~133 MB/s and spinning disks are inherently slower than SSDs.", "generated_by": "claude-sonnet", "llm_judge_score": 4}
