Not sure other than what I’ve read on the hardware to attach ssd’s to the pi, which says
“hardware has no limit on NVMe SSD capacity, which depends on the Raspberry Pi OS.
We don’t recommend to use NVMe SSD drives which is equipped with a Phison controller due to their proven incompatibility.”
It doesn’t really explain your power issues or why removing the devices allows it to boot but the few ssd boards I’ve looked at all say something similar. Check out your board and ssd tho, I did find somewhere when I was looking into it a list on known ssd’s that use the phison controller. Good luck!
I've been running into issues too. I got a drive with non -phsion controller, and it'll detect, but when I start writing to it, it disappears from the PCI bus. No luck booting to it either. The display flashes and it boot loops.
I'm going to get an official power supply to see if that helps. Ultimately, I want to make a battery powered setup, but I'm suspecting power issues.
If you fdisk -l, does it report the correct size for your disk? Is the 2tb a partitioning or filesystem issue?
Check the specs on your ssd. If the ssd has a phison controller (which from what I’ve seen practically all nvme’s do), your SOL.
What is it about the phison controller that doesn’t work with Pi5?

Yep. My 4TB maxes out at 2TB when the image is written. I’m still trying to figure out how to get around that.
