Introduction Adaptec RAID controllers support the following types of array: RAID-0 A RAID-0 is created by striping data across two or more disk drives. Simple striping like this creates no redundancy - HP Workstation xw4100 | Adaptec SCSI RAID 2120S: Software User's Guide - Page 10
Adaptec SCSI RAID 2120S/2200S Software User's Guide The cost of this redundancy is inefficient use of capacity, because all data is written to both drives, only half of the total capacity is - HP Workstation xw4100 | Adaptec SCSI RAID 2120S: Software User's Guide - Page 11
Introduction RAID-10 A RAID-10 is an example of a dual-level array and is created by using two or more equal-sized RAID-1s to create a RAID-0.
