Computer making noise, is it important?

So about a month ago, my computer started making the noise I linked here. I think it might be my hybrid drive but I don't know if it's a sound I should be worried about or if it's just the sound of it being accessed. It just seems to happen at random points in the day. I've had my pc for two years.

My build is:
CPU: Intel i5 6600 3.3ghz
CPU cooler: Cooler Master Hyper 212 Evo sleeve-bearing
Mobo: Gigabyte H170m Micro ATX
RAM: G.Skill 2x4 DDR4 2133mhz 8gb
SSD: Samsung 500gb 2.5" SSD
SHDD: Seagate 2tb 3.5" 7200rpm hybrid drive
PSU: Supernova 650w fully modular ATX
GPU: Asus geforce GTX 1070 ti

(Might need to turn up volume a bit)

Its been an hour now since I unplugged the drive and I haven't heard the sound. So, it must be something with the SSHD.
