 When `volume.balance` or `volume.fix.replication`, the volume disk type would not change.
 
+### Change by `volume.tier.move`
+`volume.tier.move` in `weed shell` can be used to change the disk type for one whole collection.
+```
+volume.tier.move -fromDiskType=hdd -toDiskType=ssd -quietFor=1s -fullPercent=0.001 -collection=benchmark -force
+```
+
+### Change by `volume.move`
 `volume.move` in `weed shell` can be used to move across volume servers:
 ```
 volume.move -source <source volume server host:port> -target <target volume server host:port> -volumeId <volume id> -disk [hdd|ssd]
 ```
 
+### Manually move volume files
 For now, if you only want to change the disk type of a volume, and the volume server is not running, you can simply move the volume data from ssd directory to hdd directory, or vice versa.
