A Solid State Drive (SSD) is a type of storage device that uses flash memory to store data, making it faster and more reliable than traditional hard drives. Unlike Hard Disk Drives (HDDs), which use spinning disks to read and write data, SSDs have no moving parts, resulting in quicker access times and lower power consumption. SSDs are commonly used in computers, laptops, and gaming consoles due to their speed and durability. They can significantly improve system performance, allowing for faster boot times and quicker file transfers. As technology advances, SSDs continue to become more affordable and widely adopted.
