The main advantage of using Solid-State Drives (SSDs) over traditional Hard Disk Drives (HDDs) is their significantly faster data access and transfer speeds. SSDs, which use flash memory, provide quicker boot times, reduced latency, and improved overall system performance. Additionally, SSDs are more durable and resistant to physical shock, as they lack moving parts, making them a reliable choice for enhanced performance in personal computers, laptops, and servers. Though SSDs may be more expensive per gigabyte, their efficiency often justifies the investment.
