1. RAID 5:
在RAID 5中,数据均分在所有磁盘中,最少需要3块物理磁盘。RAID 5的主要优点是不需要镜像空间,支持恢复时的数据访问,数据安全性高。 RAID 5 通常适用于中等级别的应用程序。

2. RAID 10:
RAID 10 也称为镜像条带。它是一个嵌套的 RAID 级别,因为它结合了两个标准 RAID 级别的功能:RAID 0 和 RAID 1。RAID 10 支持镜像和条带化功能,并且可靠性非常好。使用的磁盘数量越多,它就越昂贵,所需的最小物理磁盘数量为 4。

RAID 5 和 RAID 10 的区别:

S.No. RAID 5 RAID 10
1. In RAID 5, data is divided equally in all disks. In RAID 10, data is stored in one disk and mirrored in another disk for security of data.
2. It emphasis on data storage. While RAID 10 emphasis on performance over storage.
3. It is less reliable than RAID 10. It is far good in reliability than RAID 5.
4. In RAID 5, minimum number of physical disks needed is 3. In RAID 10, minimum number of physical disks needed is 4.
5. RAID 5 is fast in writing speed as compared to RAID 10. RAID 10 is slow in writing speed as compared to RAID 5.
6. It has more storage in comparison to RAID 10. It has less storage in comparison to RAID 5.
7. It does not support mirroring and redundancy of data. It supports mirroring and redundancy of data.
8. It is more complex as there are drives as well as parity disk. It is simple than RAID 5 due to absence of parity disk.
9. It is worthwhile as it consists of less number of disks. It is expensive as it consists of more number of disks.
