TBH the thing I hate most about this category of SBC is the reliance on SD cards. They are both too unreliable to trust and so slow that they often bottleneck the SBC. Buying them is often a crap shoot too, I've purchased cards batches of cards from the supposed reputable manufacturers that were all over the board when benchmarked, and rarely did they hit the claimed speed spec.

NVMe SSDs are so cheap now that you are literally wasting your time by not using them.

Earlier quoted context omitted.

This is pretty bad: "Does Raspberry Pi 5 need active cooling? "Raspberry Pi 5 is faster and more powerful than prior-generation Raspberry Pis, and like most general-purpose computers, it will perform best with active cooling. The Raspberry Pi Case for Raspberry Pi 5, with its integrated fan, is one way to provide this." They pose a question themselves, and don't even answer it. Of course something will perform best w…

I think they answer your question in the PSU section “Raspberry Pi 5 consumes significantly less power, and runs significantly cooler, than Raspberry Pi 4 when running an identical workload.”

I think the question is actually: "can I safely (like it's not going to melt or catch fire) use the RPI5 under any load without active cooling) ?".

I haven't had much trouble with the SD cards. The thing is, writing to them all the time means your chances of corrupting the filesystem is higher (like any filesystem). I would try to make the filesystem read-only as much as possible. There are settings for this.

Five generations in and it finally gets radical features such as:

- a power button

- a real time clock

Crazy it took this long but finally, seriously.

Downsides here are that it might need more active cooling whereas previous generations worked without it.

Also, ugh:

I'm happy that they're upgrading the pi, but it's not exactly lightweight computing in terms of power (they recommend a 27W PSU) or performance/watt (see: your cell phone) To me the charm of the raspi ecosystem was always in giving you a very low power, "always on, almost no power draw" linux environment. Oh well, I guess there's always the older versions or the zero for that.

Yeah my intel atom NUCs run at 5W idle and 10W load and they're a ton faster than a pi 4. Probably a pi 5 too. It's not very impressive. And that's with a real SSD.

NUCs cost hundreds of dollars, though. And they are probably 8x bigger, if you start stacking Pis.

isn't this just like the 4?

I've recently stumbled upon a SBC with a M.2 slot... Then promptly closed the tab, to stop the temptation to get another shiny dust collector. But they exist.

I've gone to unholy ends to syncronize large herds of Pis using a patched NTP server and several other dirty tricks.

The RTC is a huge deal to the people who care about it.
