The IO pattern for raft wal and rocksdb data are different. Is it an improvement to put them on two disks?

We'll keep writing WAL and flush memory table into disk interval. IMO, it's reasonable to put them into same disk.

Rocksdb has background compaction
wal has gc

I think it makes sense to separate WAL and data. For example, WAL could be written on faster media, such as 3dXpoint disks
