    1. Given that both hard disk drives and solid-state drives are situated inside the computer, we could also resort to external storage devices, such as portable hard disk or solid-state drives, or such transportable plug-and-play devices as a USB flash drive and an optical disc (CD, DVD, Blu-ray, etc.)
