Question

IGDTUW 2025 — Computer PYQ

IGDTUW | Computer | 2025

Which type of storage device is faster and more reliable than traditional hard drives?

Choose the correct answer:

Explanation

The correct answer is A) SSD (Solid State Drive).

Conceptual Breakdown

SSDs are widely considered superior to traditional Hard Disk Drives (HDDs) in terms of speed, reliability, and power efficiency for the following reasons:

Speed: Unlike HDDs, which use magnetic platters and mechanical read/write heads, SSDs use NAND flash memory. This eliminates mechanical latency, allowing for near-instant data access times.
Reliability: Because SSDs have no moving parts, they are highly resistant to physical shock, drops, and vibrations, which are common causes of failure in mechanical HDDs.
Efficiency: SSDs consume less power and operate silently compared to the spinning disks and moving actuators of an HDD.

Performance Comparison

In terms of data access performance, we can express the improvement in speed. If $T_{H D D}$ represents the average access time for an HDD and $T_{S S D}$ represents the access time for an SSD, the performance gain factor $G$ can be defined as:

$G = \frac{T _{H D D}}{T _{S S D}}$

Since $T_{H D D} ≫ T_{S S D}$ (due to mechanical seek time), the performance gain $G$ is significantly greater than 1, highlighting why SSDs offer faster boot times and quicker application loading.

Furthermore, the reliability factor $R$ can be viewed in relation to failure rates caused by physical wear:

$R_{SSD} > R_{HDD}$

Where $R$ represents the Mean Time Between Failures (MTBF) under shock conditions. By replacing moving mechanics with solid-state circuitry, the MTBF for SSDs is significantly higher in mobile and portable computing environments.
