A SSD is a storage device with no moving mechanical parts that houses flash memory and controllers. SSDs use the same external form factors as HDDs, because they are marketed as hard drive replacements. Using the same form factors does not require massive re-engineering of storage arrays at the factory or data center levels.
Since SSDs have no moving parts, they run considerably more quietly, enjoy faster access time, and lower power consumption over hard disk drives. And better reliability developments have made SSDs as durable as disk drives.
This means, your Windows will load in seconds, your games load fast, you won't have to wait for programs to load forever and many other benefits.
