Don't know that is so old terminology. Two kinds of hard drives available now. SSDs (Solid State Drive ) and HDD ( spinning DISK drive)
Joshua's folder is what mine will look like later today. I'm putting it in a new case, Corsair Carbide 200R. Lots of good ventilation.
In my experience, generally when you just say "disk drive" it was used to refer to a floppy disk drive. That was why I didn't know if he was joking about having a floppy drive or talking about a hard drive.
