Abstract
A storage system in one embodiment comprises a host processor, a volatile memory associated with the host processor, and a solid-state storage device comprising a non-volatile memory. The host processor is configured to detect a particular power condition, such as a power failure condition, and responsive to the detected power condition to direct the copying of data from the volatile memory associated with the host processor to the non-volatile memory of the solid-state storage device. In conjunction with directing the copying of data from the volatile memory associated with the host processor to the non-volatile memory of the solid-state storage device, the host processor further directs the solid-state storage device to enter an enhanced write bandwidth operating mode in which the solid-state storage device temporarily at least partially suspends at least one specified background process that would otherwise tend to restrict an achievable write bandwidth of the solid-state storage device.
