A solid state drive (SSD) includes different segments of nonvolatile (NV) storage media with different access times. The NV media segment with faster access time operates as a cache for the segment with the slower access time. The SSD implements idle eviction from the cache segment to the other segment based on an idle condition of the SSD. The SSD can dynamically change application of the idle eviction based on a power management state indicated for the hardware platform. Thus, a change in power management state of the hardware platform associated with the SSD can cause the SSD to implement idle eviction differently.
