Any chance we can see performance with a more realistic build with say 5 x 1TB/2TB spinning rust disks?

Power may be a concern when it comes to spinning disks.

The Taco is able to supply enough power for Seagate IronWolf NAS drives. I tested 4 of them, the one concern I have is it doesn't stagger the spinup, so if you did 5 plus a high-power NVMe you might be in trouble right at system boot.

But I was using a decent 12v 8A power supply.

What's so bad about it?

The title is accurate and the actual device is shown, isn't it?

At a glance you can see that it's a pi with a lot of attached storage, so the thumbnail actually conveys just about all you'd need to know to decide whether to watch or not. No deception.

Seems pretty reasonable.

Now if instead of the guy's face and his own hands, there was a bikini model doing yoga...

Creators are optimizing for money, YouTube's algorithm is the one optimizing for audience size.

Half of general audience has IQ below average.

That's not how averages work.

This is how IQ is defined.

No, it is not. 68.2% of the population is in the average span of 85-115 IQ. 15.9% is in the below-average span of 0-85.

I agree if we’re talking about YouTubers who are already making millions, but if you’re a smaller channel making high-quality videos, I would imagine that view bump is the difference between being able to work on producing videos full time, and having to work multiple jobs. At that point then, maybe the thumbnails do make the world a worse place, but I believe that’s offset by having more of the good-quality videos p…

The ends justify the means? I'm not convinced that's a good rationale. For one, everyone thinks their ends are the important ones so of course they justify the means, even though no one else necessarily sees it that way. Again, I point at the thread with the discussion of gym membership cancelation practices. Of course the gym can justify that to themselves: it's better for the customer because as long as they're pay…

> The ends justify the means?

So how do you justify the existence of this comment, given that the electricity used transmitting and storing it has contributed to global warming?

I have the Radxa 4 port SATA card[1], same JMicron chip, but for a pi4 via USB bridging "clip" in an aluminium heatshink chassis. Its working ok but the fan goes on a lot, I guess driving real spinning rust disks (I couldnt afford SSD) burns heat.

Also running ZFS. I love doing backups via zfs snapshot to an external drive.

I will probably buy this CM4 based unit. Just came here to say "the gear works, does what it says on the label" based on my experience with a prior card. (now unavailable I believe)

I am quite disappointed how slowly 2TB SSD are dropping in price. I use 2TB shucked SATA HDD, they were [1] https://wiki.radxa.com/Dual_Quad_SATA_HAT

I've discussed this with my brother a bit (he's a neurologist, though not a specialist in vision), and he seems to think part of it goes back to our brain's instinct to react more to 'face' than other stimuli. Therefore thumbnails with a discernible face will do better. And on top of that, an expression outside of "stock photo smile" will stand out more, and if you combine that, plus a catchy title that piques your i…

This explanation never really made sense to me. It's not like videos are hidden in a background and the thumbnail needs to stand out in our field of vision. Videos are presented front and center, and you're only looking at a few at a time. I presume everyone looks at all the video thumbnails; I just go left to right, top to bottom. Maybe if you were presented with hundreds of options at once and had to click on somet…

I just go left to right, top to bottom

I doubt this is how most people's eyes actually scan a visual field. I expect there's a lot more randomness going on subconsciously, and that face-like features cause a higher subconscious dwell time.

had to click on something quickly...but that's not how Youtube works.

I think for most people it is. Scroll scroll scroll tap, all within a few seconds.

I think it's because the thumbnails are small, so if the faces aren't exaggerated you won't perceive any particular emotion at all. It's a bit like the difference between theatre and film acting.

But that starts from the premise that you even care about the "emotion" expressed in the video. While I'm sure that there are many genres of videos where the emotions expressed by the authors are relevant to the topic at hand, there are many topics in which an expression of emotion, let alone an exaggerated one, is completely out of place.

I don't think that's true. I'm sure a lot of youtubers want people to enjoy their videos and get something from them, but they're also monetizing eyeballs. That means clicks on videos, which means grabbing attention in the video thumbnails. All other things being equal, people will click on a thumbnail with someone with an exaggerated facial expression more often than a neutral one.

As to why that works, my theory is that we're wired to respond to more extreme emotional displays because we're socially oriented great apes and that kind of information is important for navigating the world.

I get so frustrated with the idiotic thumbnails on youtube video these days. I am sure it's all optimized for the maximum number of clicks/views but if I see a still that looks the way it does at the bottom of this page I generally just don't watch it on principle.

Just look at the like/dislike ratio to judge if the video is a clicb... oh wait
