Detailed explanation-1: -Solid-state drives have no moving parts and information is saved onto integrated circuits (ICs). Although SSDs serve the same functions as hard drives, their internal parts are different.
Detailed explanation-2: -Unlike hard disk drives, flash memory is solid-state-it has no moving parts.
Detailed explanation-3: -A solid state drive is non-volatile memory (NVM) computer hardware that stores data without moving parts. Whereas hard disk drives (HDD) use a spinning magnetic disk and a mechanical write head to manipulate data, SSDs use charge in semiconductors.
Detailed explanation-4: -SSDs need less power to operate than HDDs due to their lack of moving parts. Quieter. SSDs produce less audible noise because there are no moving or spinning parts.
Detailed explanation-5: -Just like a PC consists of a CPU, memory and storage device, an SSD consists of a controller, which performs a role similar to the CPU in a PC, NAND flash for data storage, and DRAM, which functions as cache memory between the SSD and external devices.
