I'd bite if it had heat sync

Sink.

I bought 2tb 990pro from Samsung. Comparing to my 1tb hynix p41, really not big difference. Maybe p41 is slightly more responsive. But I noticed the copy speed with 990pro is faster, even between 990pro and a 2.5 inch Samsung 860 Evo. The copy speed is double the speed limit.

But if one were to have a box with good airflow, wouldn't the SSD **with** the heatsink outperform one without? Why do we have to choose between the equivalent of a sauna and a heatsink? In most cases, I think people are already moving air in and out, maybe not with optimal efficiency... But well enough that having a heatsink on their SSDs makes sense

Of course it would. I was never saying heat syncs aren't good. Thermal dynamics in an enclosed box, which is what this is, it's a computer case, says you must get the heat out of the box, heat syncs just move the heat away from an area, but if your box isn't effectively blowing the heat out, the heat sync is moot. In tandem, they work great; we use it all the time. But our priority is getting the actual heat out of the box which was my original point that he didn't understand and conflated.

Not spreading misinformation, I'm talking about an enclosed box case that has the ability for mass fan cooling. If you're pulling the heat out of an enclosed box very efficiently, it's thermally better than an 80mm heat sync on an SSD.

You clearly have no concept of thermodynamics if you think direct air contact is better than direct contact with a big chunk of metal.

First of all, it's "sink" not "sync". You sure you work for the DoD?

As for "moving the heat out", are you trying to imagine the computer case as existing inside a vacuum or made of an insulating material? If so, you're the one conflating matters.

Nobody is talking about wrapping up the case in fiberglass and letting the heatsink do all the work. There's air moving in and out, in addition to making contact with the case material, even with static pressure.

The fact remains, copper and aluminum are thousands of times better at thermal conduction than air.

If you have a material dissipating heat over a small surface area, the universal consensus is to give it more surface area by which to dissipate.

Do you think catalytic converters would get stolen as frequently if they could be contained in a 1sqin package found inside the engine and use an equivalent amount of material? Obviously not.

And if HVAC units could get away with using a lot less copper and aluminum to radiate heat, don't you think they'd do it?

First of all, I'm typing on my phone. Second, yes I work on government military projects. Third, you're not worth my time. I'll happily answer OP's questions
