RAID (Redundant Array of Inexpensive Disks) uses multiple hard drives for performance and reliability. RAID 0 uses striping to increase performance but provides no data redundancy. RAID 1 uses mirroring to provide full data redundancy but offers no performance increase. RAID 5 uses parity to provide redundancy across 3 or more drives while also increasing performance. Newer RAID technologies like RAID n offer more flexibility and reliability than standard RAID levels. The G-SPEED eS PRO XL RAID system provides fast, high capacity storage optimized for video workflows.

1. RAID TechnologyBy Nicole Moore

2. About RAIDRedundant Array of Inexpensive DrivesCreated in the late 80s early 90s to create the same or greater storage capacity at a lower price. Uses multiple hard drives for performance and reliability.

3. RAID 0Not a valid type of RAID.Uses a method called “striping”.ADVANTAGESIncreased performance. No loss in data capacity.DISADVANTAGESNo redundancy of data.

5. RAID 1First real implication of RAID.Uses a method called “mirroring”.ADVANTAGESProvides full redundancy of data.DISADVANTAGESStorage capacity is only as large as the smallest drive.No performance increases.Downtime required to change active drive during a failure.

7. RAID 0+1 and 10Hybird form of RAID.ADVANTAGESIncreased performance .Data fully redundant.DISADVANTAGESLarge number of drives required.Effective data capacity is halved.

8. RAID 1+0RAID 10

9. RAID 5Most powerful form of RAID that can be found in a desktop computer system.Requires a minimum of 3 drives to build.Uses a form of binary math called parity.Uses a method called “Hot Swap”.

10. ADVANTAGESIncreased storage array performance.

11. Full data redundancy.

12. Ability to run 24x7 with hot swap.DISADVANTAGESHigh costs to implement.

13. Performance degrades during building.(n-1)z = Array Capacityn= number of drivesz= capacity EX: Three 500GB (3-1)*5000GB= 1000GB

14. RAID nOffers higher reliability and more storage space than conventional RAID.Allows customers to select the level of protection desired.Currently implemented in Linux only.
