## Storage usage

The selection of varying data and parity drives has a direct impact on the drive space usage. With storage class, you can optimize for high
redundancy or better drive space utilization.

To get an idea of how various combinations of data and parity drives affect the storage usage, let’s take an example of a 100 MiB file stored

        SmbSessionImpl session = new SmbSessionImpl(mockContext, "testhost", "testdomain", mockTransport);

        // Session starts with usage count > 0, so acquire/release cycles maintain usage
        assertTrue(session.isInUse(), "Session should be in use initially");

        // Test acquire/release cycles (session remains in use due to initial transport acquire)

            }
