How does an SSD differ from an HDD in terms of performance and durability?

• A. HDD uses spinning platters and mechanical parts, slower and more susceptible to shock
• B. SSD has no moving parts, faster read/write speeds and better durability
• C. SSD uses slower read speeds
• D. HDD has no moving parts

Answer: (B)

The difference in performance and durability between SSDs and HDDs hinges on moving parts. An SSD stores data in flash memory with no moving components, so there is no mechanical seek time or rotational latency. This leads to much faster read and write operations, especially for random access, which makes booting, opening programs, and transferring files noticeably quicker. Durability improves because there are no spinning disks or moving read/write heads to be damaged by shocks or vibrations, making SSDs better for portable use and rough handling. HDDs, on the other hand, rely on spinning platters and a moving arm to read and write data. The physical motion introduces latency and potential wear from bumps or drops, resulting in slower performance and lower durability in terms of shock resistance. So, SSDs are characterized by no moving parts and faster speeds with greater durability, compared with HDDs. (Note: SSDs do have wear considerations over many write cycles, but modern drives manage this with wear leveling, yet the durability advantage under typical use remains.)
