How many disks can fail in a RAID 5?
The maximum number of drives in a RAID 5 set is in theory unlimited, although your storage array is likely to have built-in limits. However, RAID 5 only protects against a single drive failure. Two failures within a RAID 5 set will result in data corruption.
How many drives do I need for RAID 5?
three drives
RAID 5 provides fault tolerance and increased read performance. At least three drives are required. RAID 5 can sustain the loss of a single drive. In the event of a drive failure, data from the failed drive is reconstructed from parity striped across the remaining drives.
How to create RAID 10 arrays with mdadm?

How to convert RAID 1 array to RAID 5 array?

How to recover data from RAID 5, 1, 0?
