The main advantage of using solid-state drives (SSDs) over traditional hard drives is the significant increase in speed and performance. SSDs utilize flash memory technology to access data much faster than traditional hard disk drives (HDDs), leading to quicker boot times, faster file transfers, and improved overall system responsiveness. Additionally, SSDs are more durable due to the absence of moving parts, making them less prone to mechanical failures. Their energy efficiency also contributes to longer battery life in laptops and mobile devices, creating a more efficient storage solution for consumers.
