I have a laptop that has a SSD for the operating system drive (Windows 10). I also have a 5400 RPM HDD as a second drive for storing downloads and documents (no applications installed on it).
Recently I have been seeing pauses in other applications while the HDD spins up. This is surprising to me as all applications are installed on the SSD. Can the HDD cause delays when no applications are installed on it? Does the operating system somehow pause to wait for the HDD to spin up?
