Thank you for your response. I tried unplugging several times... I normally use a multi outlet, but I also tried directly in wall. Same problem.Okay, so it's the same Pi from the threadHi there.
I think I have a hardware problem with my Pi 5. I have a Pineberry Pi Bottom with a 4 TB SSD attached to the Pi 5 (8 GB ram). I want to use it as a NAS (and media center). Only issue is that file transfer via my home ethernet is slow... like 2-10 MB/s... mostly 2-4. And I tested for issues with ethernet. It works fine. Iperf test shows close to 1GBit/S speed between Pi5 and a Windows 11 laptop.
I tried attaching SSD in enclosure via USB-C. That works close to Gbit speed.
I tried SSD via USB and empty Pineberry hat attached. Slow.
Adding to this I had some warnings ever since I got the Pi 5 (got Hat later) that lack of power could disable some peripherals. (Forgot exact wording).
Now I bought a voltage/current tester, and it shows pretty stable 5 Volt, but less than 1 A. Even when running file transfer on SSD in Pineberry Hat.
So... big question: is my power supply (official Raspberry 27W) faulty? Or would it be the Pi 5?
Can you suggest other tests to narrow down on the problem?
Best regards
Ulrich
PS: Made additional test: Pineberry Hat with no SSD in plus SSD in enclosure via USB-C. Power supply still around 5.1 V and current a little up around 1.4 A. AND I get a "Low voltage warning - Please check your power supply". And low file transfer via Ethernet.
PS2: And another test again... this time no hat at all and only SSD via USB-C. 5.1V and 1.1-1.4A. And voltage warning again. And less slow file transfer though far from full speed.
And now I noticed during boot, the current peaks around 2A.
I can't judge if the Pi 5 isn't pulling enough power from the power supply, or if the power supply isn't working as it should??

but the focus is on the low voltage warning rather than speed on the LAN. I would not expect correct operation of a Pi 5 with a 4TB m.2 SSD under that warning.
Someone posted about an official Pi 5 wall wart that was defective on this forum within the last two months. Others observed that unplugging the wall wart from the mains and plugging it back in can reset the circuit that negotiates the USB power delivery after which it works.
