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 Disk striping with distributed parity 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 Mirror of striped drive pairs 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
