Solid-state drives (SSDs)

Definition

Solid-state drives (SSDs) are storage devices that use flash memory to store data, providing faster access times and improved reliability compared to traditional hard disk drives (HDDs). SSDs have no moving parts, which allows for quicker data retrieval, lower latency, and enhanced durability, making them a critical component in modern computer systems and architectures.
