sounds like people simply weren't taking any care of them, that's why they broke. If they had cases and decent sd cards that probably wouldn't have happened.

SD cards with wear leveling and error correction are hard to find and can easily be more expensive than similar SSDs.

I was under the impression most non-awful SD cards had some sort of wear-leveling these days but there's no standard for it so they don't advertise it on the front like SSDs. I couldn't really find any proof either-way about this, just a few instances of people looking into it:

Why isn't it just a CM plugged into the bottom of the keyboard circuit board for upgradability... it doesn't bode well that Rasberry Pi's own products aren't using the weird connecter the CM has.

I've seen a lot of devices like the CM that use a random connector and for some reason they never actually name the connector and its MPN. Alchitry and Parallela have "weird" connectors as well and it was always a pain in the ass to figure out which connector they've been using.

RPi do name the connector in the CM4 datasheet: https://datasheets.raspberrypi.org/cm4/cm4-datasheet.pdf

You can buy the connector here: https://uk.rs-online.com/web/p/products/1362374/?grossPrice=...

I agree with you though. RPi appeals to people with a wide range of skills. There are lots of programmers who want to use Pi to get more electronics knowledge, and RPi foundation could make that a bit easier for those people.

(EDIT: I don't understand why parent has been downvoted. A lot of similar devices do use newer more specialised connectors and it can be hard to work out who makes and supplies the connectors.)

As an engineer/founder from India who dreams of access to the Internet for everyone on this planet, these are the efforts that make me smile. I am in the process of sorting out my financial situation - tough founder luck. But I am happy to order a few of these (and monitors) and rent a small garage to give local kids a free computer lab to learn. (Kolkata, India)

E-waste is a massive problem nowadays. Why not assemble the lab out of "old" computers? They might take a bit more electricity to run, but, at least in the US, you can get truckloads of computers that were destined for the scrapyard, for free. One local school here threw away 50+ small dell quad-core i5's in their quest to make sure they spend their money wisely. I've assembled a small lab, with many computers, laser…

I don't know why you're downvoted.

This is exactly how it's done in many places. A 10yr old computer is perfectly fine for this, maybe even older. Yes it might not play all youtube videos, but it works.

Can we please have a Pi without a crappy storage interface. It's either a microSD card or something dangling off USB. An M2 SATA or NVMe would make this credible but 99% of the problems I've had with the Pi platform is storage related, either being knackered microSD cards, terrible performance or USB power problems.

NVMe hats are available for less than $50 Geekworm Raspberry Pi 4 X872 M.2 NVMe SSD Expansion Board Compatible with Raspberry Pi 4 Model B only, Support X735/X710/X765/X725 https://www.amazon.com/dp/B0855T2KFW

vomit. There's PCI lanes coming out of the CPU right? Even a bottom end Intel unit these days has one for an NVMe slot, not 5 devices down the bus.

Except these problems don't occur for most people, as evidenced by the fact that the current system works fine. Complaints like yours are relatively rare.

> Complaints like yours are relatively rare. I've stopped complaining because I already know how the issue manifests and how to solve it. A SD-card is not a proper replacement for a drive, it's a fine storage medium.

As far as I am concerned, I consider SD cards the equivalent of a floppy disk. The equivalent of a hard drive would then be a CF card (unfortunately much less common than SD cards these days). Or of course any USB drive if we give up on the card format/connection style.

Sounds like you're not the target audience for a RPi. They are meant to be cheap computers for "the promotion of teaching basic computer science in schools and in developing countries"[0]. Adding NVMe support would increase the price. There are alternatives to RPi that do what you want, odroid-h2plus for example. [0]: https://en.wikipedia.org/wiki/Raspberry_Pi

Or you know there's this thing called eMMC that's mostly pin compatible with SD cards and yet provide fast, resilient and cheap storage.

I believe the reason they are “eMMC” than “eSD” is because they can’t be certified for SD specs.

MMC and TransFlash at this point is a synonym for SD Card when someone cannot refer to them for license/certification reasons.

Just watched a few videos on your channel and love it. Really great stuff. I love this Pi 400 and think in the new year I will pick one up for my son. We have a Pi 4 that we use a lot and he loves but like you say in your video it is a bit annoying with this little box off the side with a bunch of cables coming out of it. Not terrible by any means just annoying so I really love the form factor of it all being in the…

>simple RPi branded monitor with a Pi built in Oh, I'd definitely be up for that!!

And make it easy to upgrade or replace later on!

There was a thread about distraction-free writing a few days ago. This is an absolutely perfect machine without having to resort to buying old laptops and hacking FreeDOS onto them.
