Hi Torsten,

Knowing you and knowing the RPi5, I strongly suggest you have a look at
alternate
platforms; my personal favourites are rk3588 based; YMMV.
The Pi5 NVME IF has only a single lane, which only works reliable at Gen2 speed.
To compare, the Rock5B I'm currently typing to has a quad-lane Gen3. The Rock
5B+
splits that into 2x2 Gen3 if you prefer. There are some boards with 2.5Gb Ether,
if you want to extend into NFS. The quad-core CPU is not bad, but the current
state
seems to be to add at least 4 more "little" cores, if not another 4
medium-sized ones.
So long story short: the Pi5 might not be the best choice starting already with
the
hardware, let alone the documentation.
I am biased here.
Just last week, i put a raspi os on my first Raspberry Pi Model B, to
use my RaspyRFM module for a POC decoding my wmbus watermeter.
What do I want to convey with this nice story?
With a Raspberry Pi I can, more than 10 years after it was initially
sold, download a up-to-date OS image *from the original vendor* and use it.
All other ARM board vendors from boards I have, provide, if at all, a
badly hacked together debian or ubuntu image with a frankenstein'd
Kernel where you are lucky to find sources at all. You can download this
image from some crazy google drive account or a dropbox link which might
be available tomorrow -- or not.
Maybe this situation has changed, and 10 years from now I will be able
to tell. Today, I continue to just use what worked well for me and
that's Raspberry Pies. I'm too old to waste time with the cheap SOC of
the day and I'd rather trade some performance for ease of use and
hassle-free operations :-D
Oh, just checked and found that the Rock5 would be significantly more
expensive than the Raspi500+ I just ordered, so remove the "cheap" in
the last sentence ;)
My obsworkers have been running on a RPi400 and two RPi4B/8GB, all with
USB-Connected SSDs, so replacing the 400 with the 500+ will be a welcome
improvement, even if theoretically there would be more performant
options available.
Best regards, and thanks for your concerns, but I prefer to not follow
your suggestion :-)
Stefan
(And yes, I know, the raspberry pi also needs frankenstein kernel hacks,
the first model until today does not run right with a mainline kernel,
this is why I use raspi os on it, but at least I can get a raspi os for
it after > 10 years).
