Given below are two statements:
Statement I: Solid State Drives (SSDs) are considerably faster than Hard Disk Drives (HDDs) when it comes to data access.
Statement II: RAM is much faster to write to or read from in comparison to secondary memory such as hard disk, but its main drawback is its volatility.
In the light of the above statements, choose the correct answer from the options given below:
Answer: A. Both Statement I and Statement II are true — ConceptA storage hierarchy balances speed, capacity, cost, and data retention. Electronic memory avoids mechanical motion, while volatile memory needs…

Show answer & explanation
Correct answer: A
Concept
A storage hierarchy balances speed, capacity, cost, and data retention. Electronic memory avoids mechanical motion, while volatile memory needs continuous power to preserve its contents.
Device performance therefore depends on the access mechanism as well as on whether the medium is primary or secondary storage.
Application
Statement I compares two secondary-storage technologies. An SSD accesses flash cells electronically, whereas an HDD must position mechanical parts before reading or writing data; the avoided seek and rotational delays make SSD data access considerably faster.
Statement II compares primary working memory with secondary storage. RAM supports low-latency electronic reads and writes for active computation, while hard-disk access is slower; ordinary RAM also loses its contents when power is removed, so volatility is its principal retention drawback.
Cross-check
The moving-parts check supports the SSD–HDD speed comparison, and the power-off check distinguishes volatile RAM from persistent secondary storage. Both checks support the two statements independently.
Contrast
Both Statement I and Statement II are true: this is consistent with electronic flash access being faster than mechanical disk access and with RAM being fast but volatile.
Both Statement I and Statement II are false: this conflicts with both the access-mechanism comparison and the power-dependent nature of RAM.
Statement I is true but Statement II is false: the SSD–HDD comparison fits the hardware mechanisms, whereas denying the RAM comparison conflicts with its low-latency, volatile role.
Statement I is false but Statement II is true: the RAM comparison fits the memory hierarchy, whereas denying the SSD–HDD comparison conflicts with electronic versus mechanical access.
Result
Therefore, both Statement I and Statement II are true.
