Toshiba N300 14TB 7200RPM SATA III 6Gb/s 3.5" Internal NAS Hard Drive

I had 2 14tb in my home office NAS and the scratching noise when reading/writing was way too loud. I guess these are more for like data centers or if your rack is somewhere like in your garage. I went with WD Red Plus 14tb instead and it is night and day. The WD Red are inaudible compared to these.

Given that Toshiba rates these drives significantly less noisy than Seagate or WD, I'm rather disappointed. Not that they are loud, but they are certainly not very quiet. Pure runtime noise is reasonable, head movement (seeks) are relatively loud. Part of that might be that the plastic housing of my Synology NAS transfers the clunks directly, but again, their specs suggest less noise. Anyways, otherwise these are good drives for a NAS, fast, large storage, well priced.
