Dell Technologies Proven Professional – Information Storage and Management (2023) — Question 10

What set of factors are used to calculate the disk service time of a hard disk drive?

Answer options

• A. Seek time - Rotational latency - Data transfer rate
• B. Seek time - Rotational latency - I/O operations per second
• C. Seek time - Rotational latency - RAID level
• D. Seek time - Rotational latency - Bandwidth

Correct answer: A

Explanation

The correct answer is A because the disk service time is influenced by seek time, rotational latency, and data transfer rate, which together determine how quickly data can be accessed and transferred. Options B, C, and D include factors that are not directly related to disk service time calculations, such as I/O operations per second, RAID level, and bandwidth.
