Striping with dedicated parity drive
RAID level 5 provides redundancy by writing data and parity information across three or more drives, thus increasing performance. The RAID level 5 provides the best combination of disk array technology.
Advantages Best balance cost / performance / protection of any RAID system Allows multiple simultaneous writes High read data rate Medium write data rate 3 drives minimum Ideal for small write applications Highly efficient Disadvantages In-efficient with large file transfer Disk failure has an impact on performance |
