SD card write speeds are much lower than read speeds for SD cards and several things can affect it like the chosen block size, etc. Also the Pi maxes out around 10MB/s so that doesn’t seem like it will be an issue.

You show the output of the dd command but not what the command was. Can you show that. Also partitioning and formatting isn’t needed when you are just dd’ing an image. The image contains the partition and formatting information.

Also showing the devices on the system with something like the following would be helpful:
sudo fdisk -l
or
sudo blockdev –report
