What do solid-state drives (SSDs) typically lack when compared to traditional hard disk drives?

Solid-state drives (SSDs) are distinct from traditional hard disk drives (HDDs) in that they do not have any moving parts. This fundamental difference is key to understanding the operational advantages of SSDs over HDDs. HDDs rely on spinning disks and read/write heads that move to access data, which makes them more susceptible to physical damage from bumps or drops and limits their speed due to mechanical latency. In contrast, SSDs use flash memory to store data, allowing for much faster data access times and improved durability since there are no mechanical components to wear out or fail.

The absence of moving parts in SSDs contributes to their reliability and enhances performance, resulting in quicker boot times, faster file access, and improved overall system responsiveness compared to HDDs. This technological advancement is one of the primary reasons why SSDs are favored in modern computing environments, especially for applications requiring speed and durability.
