Hi, I have a Pi5 with the X1001 and a weird issue.

I added dtparam=nvme to config.txt and did a reboot. (By the way in the wiki the 'sudo nano' command below 'Test Reviews' is missing '/firmware')

Now the two commands dd if=/dev/zero of=./Testingfile bs=100M count=10 oflag=direct dd if=./Testingfile of=/dev/zero bs=100M count=10 oflag=dsync gave me really slow values. About 10 MB/s

I used the imager to get a Pi OS onto the nvme. The flashing was really slow, too. Afterwards booting from the nvme worked but the desktop somehow always crashed after boot.

So back to the sd boot. I then did rpi-eeprom-update -a That didn't change anything with the speeds, but the nvme now boots and works. And when I do the two commands after booting with the nvme I get the expected speeds.

Back to the sd boot and the speeds are still horrible. What could be wrong?
