StorPool provides the following space saving features:
- thin provisioning;
- TRIM/discard;
- zeroes detection.

Discard commands are initated by the user of the storage system.

Write operations containing zeroes are detected as early as possible and converted to a metadata-only write operation.

Thin provisioning is on all the time.
