Abstract
Aspects of a storage device, a host device, and a redundant array of independent disks (RAID) system including multiple storage devices and the host device are provided that provide power control and power loss handling. The host device and the storage devices in the RAID system may each include at least a memory, a controller coupled to the memory, and a power management circuit coupled to the memory and the controller. A storage device controller may receive rationed power from the host device or a RAID controller in the host device in response to a message from that storage device indicating a detected loss in supplied power. An amount of the rationed power is based on a program data rate of the storage device or a size of data from the host device or the RAID controller to be written to the memory. Thus, UGSDs may be detected and addressed.
