What is Flash Storage?

Flash storage places digital information on solid state "flash" memory chips (i.e. What's found in a USB stick) rather than on spinning hard disks.

Flash storage definition

In the enterprise, flash storage refers to the use of solid-stage drives (SSDs) comprised of flash memory (i.e. "An All-Flash Array") for the mass storage of data or files. Flash storage offers an alternative to relying on hard disk drives (HDDs) or other media for storage. Recent advances in manufacturing have made it possible for all-flash storage arrays to hold more data per rack unit than is possible with HDDs—while performing faster input/output (I/O) operations.
