All Flash

An all-flash storage system, also know as an all-flash array (AFA) or a solid-state storage disk (SSD) system, is an external storage array that uses only flash media devices (such as NVMe or SATA SSD) for storage. Flash storage is used in place of spinning hard disk drives (HDDs) that have long been associated with networked storage systems. Benefits of using all-flash storage systems include lower latency, higher IOPS, greater storage density and reduced power consumption compared with mechanical HDDs.
