Ahoy there!
We've now got some longer PCIe cables on the store, you can find them here: https://shop.pimoroni.com/products/pcie-flex-cable-for-nvme-base-and-raspberry-pi-5?variant=41449370943571
“My first try was a Geekworm X1003, which just did not work, even after playing around some hours with 2 different SSD drives. I just lost my nerves ;-)
The Pimoroni NVMe Base: I mounted it (which was a little fiddly), the SSD was pre-initialized with the Raspberry Pi Imager, plugged in the power-cable and ... the Raspi 5 just started from the SSD. Period.
THANKS for a solution, which just works ...
Now I just have to look for a nice case for the system, any ideas?”
