9 Configuring RAID in a Dell workstation | 1.0
2.3 RAID 5 – Striping (performance) and data protection via parity
Requires at least three drives
Data is available even if one of the drives present in the volume fails, however the failed drive must be
replaced and the volume must be rebuilt to for the data to be accessible.
Total capacity = N-1, e.g. When you use 3 drives of 1.0TB size, you get a 2.0TB RAID5 volume
Disadvantage - rebuilding a large RAID5 volume can take a long time
