RAID Level 5 Explained | Tech Arkit
The problem with RAID 5 is that once a member disk has failed, one more failure would be irrecoverable. To reduce the probability of double failure you need to monitor the array and/or use hot spares. However, even if the RAID rebuild is commenced immediately once the drive fails, it is required to read the entire array in order to complete the rebuild.
