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 to protect the data, but by sharing the load equally across multiple drives, it does provide the - HP Xw8200 | Adaptec SCSI RAID 2120S: Software User's Guide - Page 10
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 available.
