The advantage of using solid-state drives (SSDs) over hard disk drives (HDDs) lies in their performance, durability, and energy efficiency. SSDs provide significantly faster data access and transfer speeds because they utilize flash memory instead of spinning disks. This leads to quicker boot times, improved application performance, and overall system responsiveness. Additionally, SSDs generally consume less power, which can contribute to longer battery life in laptops. Their lack of moving parts also makes them more resistant to physical damage, enhancing their reliability in various environments.
