If you lose one node, your data are still here. This mode will give you **50% of your total disk space** (e.g with 2x nodes of 250GiB, you'll have only 250GiB of space).

### 3-way replication

2 nodes can be destroyed without losing your data. This mode will give you **33% of your total disk space** (e.g with 3x nodes of 250GiB, you'll have only 250GiB of space).

### Building a "RAID 10" like
If you have more than 2 or 3 nodes, it could be interesting to **distribute** data on multiple replicated nodes. This is called "**distributed-replicated**" type. Here is an example with 6 nodes:

It's very similar to **RAID 10**.
It's very similar to **RAID 10**. In this example, you'll have 300GiB of data usable.
