Flash memory is a type of data storage used in Solid State Drives (SSDs) and USB flash drives, known for its speed and reliability. Unlike traditional storage media, flash memory has no moving parts, resulting in faster read/write speeds and lower power consumption. It is non-volatile, meaning data remains intact even when power is off. Due to its advantages, flash memory is widely used in mobile devices, cameras, and as external storage solutions, making it a popular choice for both consumers and enterprises seeking performance and portability.
