A Solid State Drive (SSD) is a type of storage device that uses flash memory to store data. Unlike traditional hard drives, which rely on spinning disks and moving parts, SSDs have no mechanical components. This makes them faster, more durable, and less prone to failure, as they can access data almost instantly. SSDs are commonly used in computers, laptops, and gaming consoles to improve performance. They provide quicker boot times and faster file transfers compared to their counterparts, such as Hard Disk Drives (HDDs). As technology advances, SSDs are becoming more affordable and widely adopted in various devices.
