D Supported RAID Types RAID is an acronym for Redundant Array of Independent Disks. The goal of RAID is to provide better performance and reliability from combinations of disk drives than possible with the same total storage space without RAID. When creating RAIDs, select drives of equal capacity and performance. Otherwise, the RAID tends to be limited in capacity and performance to that of the smallest and slowest drive. The Adaptec 2410SA controller supports up to four drives and supports RAID levels 0, 1, 5, 10, spanned volume, and simple volume. These array types are described below. In addition to RAID capability, the Adaptec 2410SA controller supports a simple volume configuration, which consists of a single drive that is not part of an array. Such a drive is automatically configured as a simple volume. The controller supports up to four simple volumes. D-1
