I saw many comments about choosing commerce or high performance/enterprise HDD-s to a home NAS. Related to noise. This is a clean comparison between WD Red (5400) and a WD Gold (7200). I run a random IOSP test on both. Sequential read/write is noiseless and a SSD cache can helps a lot too, so in real-life use case this is not as annoying as it sounds
