One of the key trade-offs traditionally with storage is between performance and redundancy. The more redundant a storage solution, the slower the performance as any write action needs to be duplicated in a way not necessary without less replication/redundancy. For example, holding storage in RAID1 gives much higher performance than RAID5 or RAID6. If a drive fails in RAID1, until the second drive is reconstituted, all data on the remaining drive is at risk if a further drive fails (the same is the case under RAID5). That isn?t the case with RAID6 but RAID6 under normal circumstances has much less performance.
