Solid-state storage refers to a type of data storage that uses flash memory to store information, rather than relying on moving parts like traditional hard drives. This technology allows for faster data access, improved durability, and lower power consumption, making it ideal for devices like smartphones, tablets, and laptops. Unlike hard disk drives (HDDs), which use spinning disks to read and write data, solid-state drives (SSDs) have no mechanical components. This results in quicker boot times and file transfers, as well as increased resistance to physical shock. Overall, solid-state storage is becoming increasingly popular for both personal and professional use.
