Abstract
The present invention relates to optimizing the performance of a data storage device, such as a hard data storage device, during boot operations and normal operations. In particular, during power up, the data storage device monitors the nature and progress of commands issued from a host. During boot operations, the data storage device sets its cache to a boot mode. The boot mode is designed to speed the boot process and aggressively cache data used during boot up of the data storage device and the host. The data storage device detects the transition of the host operations from boot operations to normal operations based on various criteria. The caching mode of the data storage device is then changed for normal operations based on the transition.
