I'm looking to replace an aging 1TB 3.5" SATA HDD in my i7 desktop with a 6TB drive for my data (my system drive is SSD). I favour WD as I've had no issues with them over the years. Reasonable performance is a consideration, so I was thinking in terms of a 6TB Black. But I see that WD offer a 'Gold' enterprise device as well which seem similar in spec to the Black. I did a search on here and found some reports that Gold makes more 'clicking' sounds but aside from that does anyone know what the actual differences are between Black and Gold? Cheers.
