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

I tested that last year in a couple videos comparing an ASUSTOR to a Raspberry Pi: https://www.youtube.com/watch?v=vBccak8f-VY (it works fine, though network copies are still 20-30% slower on the Pi compared to the other NAS).

I may do another video on a different NAS that has a CPU closer to the Pi's.

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.

Believe me, I had a nice discussion yesterday with my sister (who helped me take pictures for the thumbnail), and we both agreed it's one of the dumbest things about current YouTube... The thing is, from all my own A/B testing, a face vs. no face will automatically get 20-30% more views (all else equal). And an exaggerated face, a bit more than that.

The question not being asked is how your audience changes A vs B in other ways than size.

You can easily A/B test yourself into mediocrity by constantly optimizing for a larger, dumber audience. They stop liking your old content (despite your dumb faces, etc) so you make new content they like more, keep that cycle up for a while.

And you end up making emotionally charged rage-porn political videos and have become the next Facebook/cable news/etc.

This is also why the second or third album for a band is usually the best; they get popular and start letting their audience design their music and become repetitive and mildly awful.

I wonder how it affects which populations are viewing the videos. But revenue is revenue!

I honestly wonder which came first, the viewer preference or the algorithm. Like are there people out there that see a whacky face in the thumbnail and think "Oh that's a video I want to watch!" and the algorithm just got trained on that? Or did whacky faces just resemble something (from the algorithm's perspective) that was briefly popular and then a positive feedback loop of algorithm recommends it -> gets popular…

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…

I've noticed this same thing with advertisements and dancing. Why are people always dancing and singing in advertisements? Seems like people just are wired to pay attention to certain human behaviors.

Really sad to see so many people dismiss this just based on the YouTube thumbnail at the bottom. Jeff consistently makes very high quality content, I really enjoyed his series on Kubernetes, I would urge you to look past any preconceptions there. The fact is, if YouTube makes up a sizeable portion of your income, and that can increase by a factor of 10% just by making a dumb face, you’d be silly not to do so. It’s un…

> and that can increase by a factor of 10% just by making a dumb face Think more like 20-30% — and not doing it leads to a much quicker falloff from YouTube recommendations, where over 90% of video views come from. I overlook dumb thumbnails when the content is actually enjoyable/entertaining/educational.

Noting the username, are you the guy in the video?

Have you tested a difference between a regular expression (intrigued, skeptic, smiling...) and a goofy face? For science?

Booo. Its just a pi with expensive ssd disks attached. Nothing interesting here.

The difference is the Radxa Taco board, which interfaces a CM4 directly with 5x SATA III slots, 1x native NVMe M.2 (2280), and 1x 2.5G NIC. Most typical Pi 'server' builds slap all that IO on top of the Pi 4 model B's USB 3.0 bus.

And the Pi4 SoC has only 1 pcie 2.0 lane so there's little to gain over USB 3.0 save for some latency.

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

Sorry, I don't believe profit motive alone should ever be acceptable justification for making the world a worse place. You might argue that stupid faces and clickbait titles don't really make the world a worse place, and if that's the case we'll just have to agree to disagree.
