A storage usage management system includes a storage usage management subsystem coupled to first and second storage devices. The storage usage management subsystem collects first write usage data from use of the first storage device by a host mapped to the first storage device, determines that second write usage data from use of the first storage device by the host exceeds first metric(s) associated with the first write usage data by a first threshold, and collects the second write usage data and third write usage data from immediately subsequent use of the first storage device by the host. If the storage usage management subsystem determines that the second and third write usage data exceed second metric(s) associated with the first write usage data by a second threshold, it uses the second and third write usage data to determine whether to remap the host to the second storage device.
