Dispersed

Dispersed volumes offer a good balance between high availability and performance; this should be the go-to volume when both are a requirement. Configuring a dispersed volume is a more complicated process since the redundancy is handled as in a RAID5 setup, where a node is used as parity. The redundancy value can be chosen at the time of volume creation which allows for greater flexibility.

In the following diagram, you can see that losing one node does not disrupt the volume:

Plan for high availability when there is a specific requirement. Remember that volume types can be mixed and matched. For example, a distributed replicated volume will have a good mix of available space and redundancy.
