Which RAID Set should I use?

Which RAID Set should I use?

Notes:

  • Please use the following chart to determine which RAID set you should use.
  • Please note that the G-Speed Q can only be used in either RAID 0 or RAID 5.
  • The G-Speed eS and G-Speed eS Pro will have different RAID sets available depending on the feature set of the RAID controller card you are using with the array.
RAID Level Description Advantage Disadvantage Ideal...
0 Disk striping Offers the highest performance and a useable storage capacity of 100% of total available storage capacity No fault tolerance- failure of one drive in the array results in complete data loss Content creation applications requiring highest storage capacity
1 Mirror of two drives Maximum level of data protection as identical data is written to multiple drives Useable storage space is 50% of total available capacity Applications in which data security is paramount
5 Disk striping with distributed parity High read performance, medium write performance with data protection in case of a drive failure Useable storage capacity equals total capacity of all drives in the array, less the capacity of one drive.

Example:
4 TB - 1 TB(for RAID 5) = 3TB usable capacity

Disk failure results in drop in performance

Content creation applications requiring data protection
10 Mirror of striped drive pairs Higher performance than RAID 1 with same level of data protection Useable storage space is 50% of total available capacity Content creation applications requiring data protection
JBOD "just-a-bunch-of-disks" Each drive can be accessed as an individual volume No fault tolerance Audio applications, General Usage
6 Disk striping with dual distributive parity Similar to RAID 5, but you can have 2 drives fail and still have access to your data. Usable storage capacity equals total capacity of all drives in the array, less the capacity of two drives.

Disk failure results in drop in performance
Content creation applications requiring data protection
50 RAID 0 striping across low level RAID 5 arrays. Improvement on the write speeds and better fault tolerance compared to RAID 5. Allows 1 drive failure per RAID 5 in the RAID 50 array Usable storage capacity equals total capacity of all drives in the array, less the capacity of two drives Applications that require high fault tolerance and capacity
60 RAID 0 striping across low level RAID 6 arrays. Allows 2 drive failures per RAID 6 in the RAID 60 array Usable storage capacity equals total capacity of all drives in the array, less the capacity of four drives Applications that require high fault tolerance and capacity
