RAID 0
| RAID 0 provides disk striping across all drives in the RAID subsystem. RAID 0 does not provide |
| any data redundancy, but does offer the best performance of any RAID level. RAID 0 breaks up |
| data into smaller blocks and then writes a block to each drive in the array. The size of each block is |
| determined by the stripe size parameter, set during the creation of the RAID set. RAID 0 offers |
| high bandwidth. By breaking up a large file into smaller blocks, MegaRAID can use multiple SCSI |
| channels and drives to read or write the file faster. RAID 0 involves no parity calculations to |
| complicate the write operation. This makes RAID 0 ideal for applications that require high |
| bandwidth but do not require fault tolerance. |
Uses | RAID 0 provides high data throughput, especially for large |
| files. Any environment that does not require fault tolerance. |
Strong Points | Provides increased data throughput for large files. No |
| capacity loss penalty for parity. |
Weak Points | Does not provide fault tolerance. All data lost if any drive |
| fails. |
Drives | One to 32 |
