Data/index storage and WAL are located under the same root by default.
However, this is not mandatory: *storagePath* and *walPath* properties 
can contain both absolute and relative paths. If paths are absolute, 
storage and WAL can reside on different devices, like this:

> storagePath: /storage1/NMVe_drive/storage
> walPath: /storage2/Big_SSD_drive/wal
We even recommend this in tuning guide: 

That's why I think *persistencePath* is misleading.
