 For example, one volume server can have two disks with two kinds of disk types:
 ```
-weed volume -max=10000 -disk=hdd,ssd -port=8080 -dir=/data,/ssd -compactionMBps=40  -minFreeSpacePercent=7
+weed volume -max=10000 -disk=hdd,ssd -port=8080 -dir=/large_data,/fast_data -compactionMBps=40  -minFreeSpacePercent=7
 ```
 
-Please notice the `-disk=hdd,ssd & -dir=/data,/ssd`.
+Please notice the `-disk=hdd,ssd` and `-dir=/large_data,/fast_data`.
 
 Then you can create with `fs.configure` a path specific setting and set buckets/collections that start with (example)  "ssd_" to be allocated to the ssd, and all other collection will be created on the hdd. you can also create specific bucket name.
