Operating a RAID system requires at least two or more storage drives. These work together and form a group of drives. This is also more efficient than one single drive.
RAID systems offer the following advantages:
Level | Explanation | Pros | Cons | Number of possible hard disks in XH270 | Volume capacity |
---|---|---|---|---|---|
RAID 0 | Striping means a mode of operation where data is shared across multiple disks to improve performance. | Increased transfer rate | No protection from loss of data | 2, 3, 4 | Sum of all disk sizes |
RAID 1 | Writes identical data to both hard disks at the same time. | Provides data redundancy | Only 50% volume capacity | 2 per RAID | Smallest hard disk size |
RAID 5 | Implemented block-level striping with parity data shared across all included disks makes data redundancy more efficient than RAID 1. | More efficient data redundancy than with RAID 1 | - | 3, 4 | (X*- 1) x (smallest hard drive size) |
RAID 10 | The combination of RAID 0 and RAID 1 doubles the performance as compared to RAID 1. | Doubles the performance in comparison to RAID 1 | Low total capacity | 4 | (X* / 2) x (smallest hard drive size) |
The following requirements must be met before setup.
