[HDD] Seagate BarraCuda 8TB Internal HDD – 3.5 Inch 5400 RPM $150 @$18.75/TB
If anyone cares, these drives are slow (SMR), but they're practically silent. I upgraded a NAS at home with a 16TB Exos after accumulating 4 years of 24x7x365 operation, and the sudden lack of silence is... Noticable.
Thanks for the heads up, I've got very loud spinners I wouldn't mind replacing.
