The main advantage of using SSDs (Solid-State Drives) over traditional hard drives (HDDs) is their significantly faster data access speeds. SSDs utilize flash memory, resulting in quicker boot times, shorter application load times, and improved overall system responsiveness. Additionally, SSDs are more durable, consume less power, and generate less heat than HDDs. While SSDs may have a higher cost per gigabyte, their performance benefits make them an increasingly popular choice for both personal and enterprise storage solutions.
