The question is a little vague. A normal hard drive, flash drive, and solid state drives can be considered all three.
One way could be to check the code of the program.
But of course this might not be possible... Not everyone knows a programming language. And even if you did, you might not know the programming language they used.
Another way is to download a program that monitors your incoming connections and outgoing connections from your computer/android/iphone.
When someone or something connects to your device, the program should alert you. Or when the computer makes a connection to a website/device.
