What is flash array storage?
An all-flash array (AFA), also known as a solid-state storage disk system or a solid-state array, is an external storage array that uses only flash media for persistent storage. Flash memory is used in place of the spinning hard disk drives (HDDs) that have long been associated with networked storage systems.
What is a disk array used for?
A storage array, also called a disk array, is a data storage system for block-based storage, file-based storage, or object storage. Rather than store data on a server, storage arrays use multiple drives in a collection capable of storing a huge amount of data, managed by a central management system.

- Select Array Configuration Utility.
- Select Initialize Drives.

Is USB flash drive faster than HDD?
Flash storage drives consume up to 50% less power than similar capacity HDDs, and are capable of much faster read/write speeds. Average HDDs cap out at 120 MB/s, while many Flash drives are capable of read/write speeds in excess of 500 MB/s. Importantly, Flash drives do not suffer from fragmentation issues.
Is flash same as SSD?
Flash storage and SSD are two terms that are sometimes used interchangeably, too. Unlike DRAM/RAM/memory, flash and SSD are not referring to the same thing, even though flash memory is used in SSDs and flash storage can be considered an SSD.
