Comparison of Single RAID Levels RAID 0 RAID 1 RAID 5 RAID 6 Diagram Description Striping Mirroring Striping with Parity Striping with Dual Parity Minimum Disks 2 2 3 4 Maximum Disks Controller Dependant 2 Controller Dependant Controller Dependant Array Capacity No. of Drives x Drive Capacity Drive Capacity (No. of Drives - 1) x Drive Capacity (No. of Drives - 2) x Drive Capacity
Comparison of Single RAID Levels RAID 0 RAID 1 RAID 5 RAID 6 Storage Efficiency 100% 50% (Num of drives – 1) / Num of drives (Num of drives – 2) / Num of drives Fault Tolerance None 1 Drive failure 1 Drive failure 2 Drive failures High Availability None Good Good Very Good Degradation during  rebuild NA ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]
Comparison of Single RAID Levels RAID 0 RAID 1 RAID 5 RAID 6 Random Read Performance Very Good Good Very Good Very Good Random Write Performance Very Good Good (slightly worse than single drive) Fair (Parity overhead) Poor (Dual Parity Overhead) Sequential Read Performance Very Good Fair Good Good Sequential Write Performance Very Good Good Fair Fair Cost Lowest High Moderate Moderate+
Comparison of Single RAID Levels RAID 0 RAID 1 RAID 5 RAID 6 Use Case ,[object Object],[object Object],[object Object],[object Object],Non-write intensive OLTP applications / file servers etc Non-write intensive OLTP applications / file servers etc Misc - - Parity can considerably slow down system Not supported on all RAID cards
Understanding the Parity Penalty ,[object Object],[object Object],[object Object],[object Object],+12124286429  Disk 1 Disk 2 Disk 3 Disk 4 A (01000001) B (01000010) C (01000011) {P – 01000000} Parity {P} D E F G Parity {P} H I J K Parity {P} L

Understanding the Parity Penalty ,[object Object],[object Object],[object Object],[object Object],[object Object]
Comparison of Nested RAID Levels RAID 10 RAID 50 Diagram Description Mirroring then Striping Striping with Parity then Striping without parity Minimum Disks Even number > 4 > 6 Maximum Disks Controller Dependant Controller Dependant Array Capacity (Size of Drive) * (Number of Drives ) / 2 (Size of Drive) * (No. of Drives In Each RAID 5 Set - 1) * (No of RAID 5 Sets)
Comparison of Nested RAID Levels RAID 10 RAID 50 Storage Efficiency 50% ((No. of Drives In Each RAID 5 Set - 1) / No.  of Drives In Each RAID 5 Set) Fault Tolerance Multiple drive failure as long as 2 drives from same RAID 1 set do not fail Multiple drive failure as long as 2 drives from same RAID 5 set do not fail High Availability Excellent Excellent Degradation during rebuild Minor ,[object Object],[object Object],[object Object]

Infact the entire worlds storage is projected to hit 988 exabytes (2 ^ 60) by 2010]  [6 th  Sep 2007 -  http://www.networkworld.com/newsletters/stor/2007/0903stor2.html  – Nanotech breakthrough could put entire YouTube contents on an iPod-size device]
