For enhancing operations, storage hierarchies often have a volatile buffer coupled to a lower performance retentive store. The integrity of the data stored in the volatile buffer is subject to power perturbations. When a user supplies data to the storage hierarchy (write) and no space is allocated in the volatile buffer, then the data is sent directly to the retentive store; otherwise, the data is written to the buffer, then to the retentive store. In accordance with this operation, the number of times that a user writes data to the storage hierarchy, where space is allocated in the volatile buffer for such data, is minimized for ensuring writing directly to the retentive store to the exclusion of the buffer.
