Is there any degradation copying files between different media?

I am going on a photo trip tomorrow. I will bring along my laptop to transfer the days shoots into the laptop. I have plenty of external hdd for backup purpose and I am quite confident that there is no degradation when I copy the file from the camera's CF memory card into the SSD in the laptop, and then to the external HDD. But I don't want to bring the external HDD with me. I have a 32gb (that's plenty for backup of this trip) microSDXC card which I can stick to the memory slot with a sleeve/adapter.

The chip itself is like the size of my little finger nail. I am wondering if the transfer to the much smaller media would degrade the quality of the image file. My instinct tells me that it won't because there is not compression in the plain drag and drop copying.

Am I right? Do I have to be concerned?

Depends on the media.

1:1 digital copies don't degrade, if you encode into a lossy file format from the original then you'll lose quality.

For your uses just copying files doesn't degrade anything as you have the exact same data as when you started.

Thanks.
That's what I think. More comfortable with the confirmation.
