US Patent 9207947 Fast boot in hybrid drives

The disclosure is related systems and method for improved boot and resume from hibernate times in hybrid drives. In one embodiment, a device may comprise an interface circuit to communicate with a host device, a first nonvolatile data storage medium, and a controller configured to monitor the interface circuit for a trigger event and pin data associated with read requests to the first nonvolatile data storage medium during a first specific duration in response to the trigger event. Another embodiment may be a method comprising receiving a trigger event, monitoring a duration since the trigger event, retrieving data from a nonvolatile cache memory, retrieving data from a disc memory when the data is not in the nonvolatile cache memory, and pinning the data retrieved from the disc memory to the nonvolatile cache memory.
