Techopedia Explains Solid State Drive

SSD incorporates the storage technique implemented in microchip-based flash memory, where data is electronically stored on flash memory chips. An SSD is an entirely electronic storage device, and its physical assembly contains no mechanical objects.

A SSD has two key components:

  • Flash memory: Contains storage memory.
  • Controller: An embedded microprocessor that processes functions, like error correction, data retrieval and encryption. Manages access to input/output (I/O) and read/write (R/W) operations between the SSD and host computer.
