Is this Seagate Exos genuine?

I just received my brand new Segate Exos X20 (actually, two of them, for my new ZFS pool), but I was wondering if it's genuine: https://i.imgur.com/OHdcjxb.png

Compared to the images online, there isn't the fancy Exos logo on top (image from web, for comparison).

Also, I read on the web that is more noisy that the average hard drive, so I was expecting to hear a noisy motor, but actually the motor itself is very quiet, I think quieter than the other drives I own, but the drive it's very noisy when it read or write data (it looks like there is a hamster wheel inside). Is it normal?

Also, not on this unit, but on the other one that I'm testing right now, I noticed a small dent on the enclosure. Should I be worried, or as far it works properly I should be fine? (I'm running a full disk test using f3, feel free to recommend me better tools)

Thank you guys!
