The sound is not right. This clicker sounds like a Geiger counter ticking out of control. The HDD sound is much deeper. It should sound as if the minute hand on a clock decided to tick out of control.

Because what you hear on a real HDD is the seeks, and the seek time of any SSD is close enough to zero that it probably won't even show up on the HDD LED. All that's left is the data transfer, which are more or less silent on real mechanical HDDs.
That's part of the reason why it was useful to have the HDD LED despite fact you already had the loud HDD. The LED showed data transfer, while the sound indicated seeks.
A nice portfolio art piece for GitHub (could even be useful for keeping an ear on virtual machines)
Come to think of it, maybe the best way is to run the whole system on a VM with a simulated HDD that includes all the delays of a real one, and sound generation. Could also do optical drives.
