RAID代表独立磁盘冗余阵列,是用于磁盘组织以提高可靠性和性能的技术。 RAID 0代表Redundant Array of Independent Disk level 0RAID 1代表Redundant Array of Independent Disk level 1都是RAID的类别。 RAID 0 和 RAID 1 的主要区别在于,在 RAID 0 技术中,使用了磁盘剥离。另一方面,在 RAID 1 技术中,使用磁盘镜像。


S.NO RAID 0 RAID 1
1. RAID 0 stands for Redundant Array of Independent Disk level 0. While RAID 1 stands for Redundant Array of Independent Disk level 1.
2. In RAID 0 technology, Disk stripping is used. While in RAID 1 technology, Disk mirroring is used.
3. The cost of RAID 0 technology is low. While RAID 1 is costly or expensive.
4. In RAID 0, There is no write penalty. While in RAID 1, There is write penalty.
5. The Relative storage efficiency of RAID 0 is 100%. While the relative storage efficiency of RAID 1 is 50%.
6. The write performance of RAID 0 is better than RAID 1. While the write performance of RAID 1 is slower than RAID 0.
7. RAID 0 emphasis on data accessing speed. While in RAID 1, data availability is emphasized.
8. RAID 0 is well in read performance. While RAID 1 is moderate in read performance.
9. In RAID 0, there is no protection available. In RAID 1, mirror protection is provided.
