Zusammenfassung:A data storage device having improved protections for in-flight data during a safety event, such as an autonomous-driving-vehicle collision. In an example embodiment, in response to a distress-mode indication signal, the device controller operates to prioritize more-recent data with respect to older counterparts of the same data stream for flushing from the volatile-memory buffers to the non-volatile memory. In addition, the device controller may operate to positively bias the flushed data towards better survivability and/or more-reliable routing.
