I think rocksdb can support this configuration.

But sata disk is not suitable for doing sync request. ssd disk is more suitable. So I think whether we could separate leveldb *.log file with *.sst file and move *.log to ssd disk, which is similar with journal file in ceph. But now, the original leveldb do not support to separate log file and sst file. Wait for your comment.
