Does anyone know any board that is similar to RPi 4, with 8GB of RAM or more and a SATA port or an nvme slot? ARM would be great.

Many systems based on Rockchip RK3399 have a native SATA/nvme interface, but only go up to 4GB ram.

Just wanted to note that you DO get a large (measurable) performance increase using NVMe natively via the Pi's PCIe bus vs. through a USB 3.0 adapter; see my notes in my Compute Module 4 review: https://www.jeffgeerling.com/blog/2020/raspberry-pi-compute-... I should probably dedicate a post and video to NVMe support, but basically you get double the random IO numbers if using NVMe vs NVMe-via-USB3. You can't boot of…

Looking forward to getting my hands on one :-) Next time you speak to the RPi folks, feel free to name-drop. Getting into the "RPi alpha tester club" would be very helpful for writing tutorials like this.

USB cables are some of the worst designed crap I have ever seen in the history of computing. When you plug the cable in, it doesn't make a firm, snug fit, and jiggles around in place. If you press down on it it can even torque the connector right off the PCB. I often have to design 3D printed housing to go around the USB plug housing to hold and lock the plug snugly in place, because the designers of both the USB por…

> jiggles around in place I don't want to defend USB too heavily (as you say, it is certainly not "industrial grade," but I don't know what the equivalent of something simple and very strong like a Hubbell twist-lock connector would be in data transfer terms, and that's something to contemplate) but this really shouldn't happen with any halfway decent cables or hardware. It doesn't apply to the Raspberry Pi 4 in my e…

Well, the best brand cables jiggle around. I'm talking Pi's, Macbooks, Pixel phones, you name it, they all jiggle around.

I've had RealSense cameras, StarTech USB hubs fail because of cable jiggling around in the port, and had to make 3D printed add-ons to grip the housing and prevent cable jiggling.

I've personally had WAY more problems with USB that SCSI cables, honestly. Also I break an average of about 1 USB cable a week; SCSI, DB25, DB9, DB15, BNC, and those cables never break.

BNC has always been trouble-free for you? That's interesting.

I think the only cable type that was entirely trouble-free for me over the years was the parallel printer cable with the truly awful Centronics connector. I don't remember ever throwing one of those away. Of course, that's not a cable that you'd plug and unplug much, which certainly helps.

There's a lot of countermeasures listed here in the responses, including this. :) Good to know but the default experience matters. I have a beef here and I want the author to know that they need to switch blog host if they want their articles to be out on the open web and not behind logins or whatever.

I was careful to only quote the first sentence of the comment. I understand and agree with the point being made in the remainder of the comment.

I also think the "default experience" matters in terms of web browsers. Why do they all default to Javascript and cookies enabled. In this case, and there are hundreds of thousands of others, neither was technically necessary to read the blog.

One needs to login to read. I'm sorry, medium is not a very charitable blog host, and will cost the blog a large part of its audience with these new rules, unfortunately.

I'm getting pretty irritated that the Web is inundated with Medium. It used to be just a nice blog host, and now I don't even know what it is. Glad Substack is picking up steam.

How is substack today different from Medium a few years ago? More importantly, what's different about their incentives that will prevent them from becoming what Medium is today?

This is just plugging in NVMe over the USB 3 port? I was expecting this to be soldering something to PCIe lanes coming out of the SoC. Is this going to be any better than using an SSD with UAS which is what I'm doing already? ( https://rwmj.wordpress.com/2020/09/24/raspberry-pi-4-running... )

There are some numbers included. If you can link to a reliable UAS SSD product, I can buy one and try it out to compare.

I don't think you understand how Medium works. This is part of the paywall, pay-wall is opt-in for content.

And incognito browser will get you to read the post for free, but I won't get any royalties as the author, if that's what you want.

I honestly don't understand why developers have such a problem valuing their time and the time of others.
