A flash array, also called an all-flash array, is a solid state storage system that contains multiple flash memory drives instead of spinning hard disk drives. Flash memory, which has no moving parts, is a type of nonvolatile memory that can be erased and reprogrammed in units of memory called blocks. It is a variation of erasable programmable read-only memory (EEPROM) and got its name because the memory blocks can be erased in a single action or "flash." A flash array can transfer data to and from solid state drives (SSDs) much faster than electromechanical disk drives, however, flash is more expensive than spinning disk
