1-3 Introduction Adaptec RAID controllers support the following types of array: RAID-0 A RAID-0 is cr eated by striping data ac ross two or more d isk drives. Simple striping li ke this creates no r edundancy to protect the data, but by sharing the load equally across multiple drives, it does provide the best r e ad and write performance of any RAI[...]

1-4 Adaptec SCSI RAID 2120S/2200S Software User’ s Guide The cost of this redundancy is in efficient use of capacity , because all data is written to both drives, only half of the total capacity is available. RAID-1 offers no write performance advantage over a s ingle drive, but read performance benefits fr om being able to share the load between[...]

1-5 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 cr eate a RAID-0. The top level RAID-0 shares the load among the second level RAID-1s, impr oving both r ead and write performance. Since second level arrays ar e RAID-1, only half the total capacity of the drives in the[...]
