Detailed explanation-1: -Registers are the fastest of all forms of computer data storage. Processor cache is an intermediate stage between ultra-fast registers and much slower main memory.
Detailed explanation-2: -A flash solid-state drive (SSD) is a non-volatile storage device that stores persistent data in flash memory. There are two types of flash memory used in SSDs–NAND and NOR.
Detailed explanation-3: -Because it uses integrated circuit technology, flash storage is a solid-state technology, meaning it has no moving parts. When flash technology is used for enterprise storage, the term flash drive or flash array is often used interchangeably with solid-state drive (SSD).
Detailed explanation-4: -SSDs deliver ultra-fast random data access (inputs-outputs per second, or IOPS, performance), low power consumption, small size and high physical resilience (due to no moving parts)-but they cost more. Hard drives provide fast sequential data access with high capacity, endurance and reliability at a much lower price.
