Non-volatile memory is a very advanced storage technology. It does not use continuous power to keep the data or program files located on the computer so that it becomes an effective power saver.
System manufacturers make a variety of non-volatile memory chips for various purposes. For example, non-volatile memory can store controller program code for devices, such as hard disk drives (HDD) and disk tapes. Other types of non-volatile memory (NVM) are commonly used to save data in USB storage, solid-state drives (SSD) or devices such as memory cards and smartphones, etc.
Solid-state storage usually uses a non-volatile memory type known as the Flash memory. SSDs do not have moving components and are capable of output higher than HDDs and tape that use ahead to read and write data to magnetic storage media. SSDs directly connected to a device’s processor through a PCI Express bus that provides lower latency than Serial-Attached SCSI or Serial Advanced Technology Adapter-based SSDs attached to an external disc.
