Method of calculating the available capacity before configuring RAID
1. You can view the available capacity during RAID array configuration. 2. You can also estimate the ? RAID 0: 100% ? RAID 1: 50% ? RAID 5: (N-1)/N ? RAID 6: (N-2)/N ? RAID 10: 50% ? RAID 1E: (N+1)/2N ? RAID 50: (N-M)/N ? RAID 60: (N-M*2)/N N indicates the number of member hard disks in a RAID array. M indicates the number of sub-groups of a RAID array. For example, if three 300 GB disks are used to create a RAID 5 array, Disk usage rate: (3-1)/3 = 2/3 Available capacity of the RAID 5 array: 3 x 300 x 2/3 = 600 GB
