Censorship and Memory-holing

This is very complicated to just give an answer, because:
It varies greatly based on the content. Animated compresses vastly differently than an action movie.

Varies greatly based on encoder. NEVC vs CPU etc

Varies greatly based on encoder options. I.e. -b:v -minrate -maxrate vs -rc vbr -qmin -qmaxcq values, etc

Varies greatly based on who is watching, the TV they use and their tolerance and experience.

Savings are greater at 4k than 1080p. But once you start adding HDR into the mix, you’re in a whole new world.

Even the people with very discerning eyes can’t agree on everything related to this topic. Wish I could just tell you do x… but you’ll have to test various methods and determine what you are happy with.
or, if you just want some space savings… use some default setting that cuts it in 1/2 and forget about it.

Sure, I have hit 10TB/mo. I’m making sure I get my money’s worth for paying $10 to have unlimited with comcast.

I think in general they have lower RPM and run a bit cooler and use a little less power. That usually comes with a bit less performance.

But I’m hooked on the WD Ultrastar series. Server Grade and fast. Also has low power usage, at full tilt, mine use less than 10w each. I’m running 20 hc530’s and been rock solid.
