1. At least one non-transitory computer readable storage medium comprising a set of instructions, which when executed by a processor, cause the processor to:
detect internal information associated with a solid state drive (SSD), wherein the processor is to be external to the SSD, wherein the internal information is to include a first measurement of host-issued input/output (I/O) data and a second measurement of media I/O data;
detect background operations with respect to the SSD based on the internal information, wherein the background operations are to include one or more of current operations or predicted operations, and wherein the background operations are detected based on there being a larger amount of the media I/O data than the host-issued I/O data; and
adjust a hierarchical data placement policy based on the background operations.
