Recently received a new Toshiba X300 6TB HDD. I am a bit worried as this drive is much louder than any other HDD I've ever owned and when writing large amounts of data I hear a minor clicking sound every 5-6 seconds. When this drive is plugged in the noise emitted from my case at idle practically doubles and you can certainly hear the X300 6TB, which sounds like a muted grinding noise. However the noise is far from being "loud", but in a quiet room you will hear it. Here is an admittedly poor quality video I took which has the "clicking noises" (when writing data): Crystal Disk Info: https://i.imgur.com/yv7CwDF.jpg My case is a Fractal Design Define S, which does include rubberized spacers for the HDDs to minimize the sound as well as padding on the side panels. For reference, I've only ever had 7,200 RPM drives including WD Blacks were are practically silent in comparison. Currently I run a 5 year old WD Black 2TB which is essentially noiseless, as well as a 7,200 RPM Toshiba 3TB P300 which is also essentially noiseless. Does this seem normal for an X300 6TB? I've read reviews of this drive being quiet but it is certainly louder than any WD Black or Seagate 7,200 RPM I've ever owned. Testing wise I've disconnected case fans to see if any were wearing out one by one and those made no difference. The noise levels return to near silent when I remove the X300 and return when I reinstall it, so it is clearly the X300 and not a case fan or the WD Black.
