It's imagine both of those would be louder than a circular saw going that speed!
yep, exos drive and 7200rpm - very good drive!
gutted missed this :(
Not if they are 8TB or more - none of those physically spin at 5400 RPM: https://blocksandfiles.com/2020/09/04/what-madness-is-this-wd-5400-rpm-8tb-drives-sound-like-faster-7200-rpm-spinners/
But the WD white labels usually are 5400rpm. Thats just my concern as they sit on my desk in my server.
