Which type of storage device typically uses flash memory?

The correct answer is Solid State Drive, which is primarily characterized by its use of flash memory. Flash memory is a type of non-volatile storage technology that retains data even when power is turned off. This feature allows Solid State Drives (SSDs) to provide faster data access speeds, lower latency, and greater durability compared to traditional storage devices that use spinning disks, like hard drives. Since SSDs have no moving parts, they are less prone to mechanical failure and can withstand shocks and vibrations better.

In contrast, hard drives rely on magnetic storage and spinning disks, and while external hard drives may also utilize this technology, they generally connect via USB or other interfaces for portability. Optical disks, such as DVDs and CDs, use lasers to read and write data, making them fundamentally different from flash memory storage. Thus, the unique characteristics and technology behind Solid State Drives make them the clear answer regarding which type of storage device typically employs flash memory.
