Huawei Certified ICT Associate – Storage (HCIA-Storage) — Question 35

What is the main difference between mechanical drives such as SAS with solid state drives (SSD)?

Answer options

• A. The lifespan of hard drive.
• B. The presence of mechanical parts.
• C. The capacity of hard drive.
• D. The performance of the hard drive.

Correct answer: D

Explanation

The correct answer is D because solid state drives (SSD) typically offer significantly better performance compared to mechanical drives like SAS due to their lack of moving parts. Options A, B, and C, while relevant, do not capture the primary difference in speed and performance that SSDs provide over mechanical drives.
