<p>Migrated comment #5350</p> <p><b>New page</b></p><div>Hi, I have a Pi5 with the X1001 and a weird issue.<br /> <br /> I added dtparam=nvme to config.txt and did a reboot.<br /> (By the way in the wiki the &#039;sudo nano&#039; command below &#039;Test Reviews&#039; is missing &#039;/firmware&#039;)<br /> <br /> Now the two commands<br /> dd if=/dev/zero of=./Testingfile bs=100M count=10 oflag=direct<br /> dd if=./Testingfile of=/dev/zero bs=100M count=10 oflag=dsync<br /> gave me really slow values. About 10 MB/s<br /> <br /> 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.<br /> <br /> So back to the sd boot.<br /> I then did rpi-eeprom-update -a<br /> That didn&#039;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.<br /> <br /> Back to the sd boot and the speeds are still horrible.<br /> What could be wrong?&lt;!-- migrated from Comments; original IP: 217.88.244.114 --&gt;</div>
