G-DRIVE 6TB Thunderbolt 3, slight ticking

Hi!
I have just started using my first G-DRIVE, I have always had Lacie discs.
I don’t have a thunderbolt 3 port on my iMac, it is connected with USB 3.0.
I noticed from the first connection, that the disk makes a slight working noise, every 3-4 seconds, even if the disk is not performing operations. The disk seems to work correctly, I’m copying files I don’t see any problems, but the noise continues. Maybe it’s normal, I ask you because I don’t know G-technology products.
tnx
Met
