SK0-004 · Question #9
A technician is tasked to build a server requiring the fastest possible performance. Which of the following would achieve this requirement?
The correct answer is C. SSD. SSDs provide the fastest storage performance due to the absence of moving mechanical parts, eliminating rotational latency and seek time entirely.

Why each option
SSDs provide the fastest storage performance due to the absence of moving mechanical parts, eliminating rotational latency and seek time entirely.
10,000 RPM SATA drives are mechanical and limited by rotational latency and seek time, making them substantially slower than SSDs.
15,000 RPM SAS drives are faster than SATA but still mechanical, meaning they cannot match the near-zero latency of flash-based SSDs.
SSDs use NAND flash memory with no moving parts, delivering sub-millisecond access times compared to the milliseconds required for mechanical drives to spin and seek. Unlike HDDs, SSDs have no rotational latency or physical seek time, making them significantly faster for both sequential and random I/O. This makes SSDs the clear choice when maximum server storage performance is required.
USB is an external peripheral interface not designed for high-performance server storage, and its bandwidth and latency characteristics are unsuitable for this purpose.
