A group of hard drives or solid state drives (SSDs) built into a single unit. A storage array may be configured in a RAID architecture for redundancy or speed (see
RAID). Also called a "drive array," a storage array generally refers to disks or SSDs; however, optical drives (CD, DVD, etc.) also come in multi-drive units (see
optical disc library). See
hard disk,
SSD,
JBOD,
