I shoot a lot more sports images than wildlife during most of the year so I can often shoot 10,000+ images on multiple cards over a weekend before I get time to cull and import images. I prefer a card reader and have imported that way since the days of my D70.
I will copy the images from the card to a scratch disk, a temporary disk storage location that is not part of my backup process. If I have time I will do the first culling of images using Photo Mechanic. If I don't have time to cull, I will duplicate the scratch disk content to another drive (not part of backup) so I can format the cards if needed. I do this so I have two copies of the images. I will cull from 10,000 image down to less than 1,500 images during the first culling process. I want to have some redundancy to the 10,000 images until I can remove the duds but I don't want the duds to become part of my backup process. Once I have done the initial culling and ingesting through Photo Mechanic to my work drive, I then run a sync process to add the 1500 images to my storage drive where they will become part of my backup process. I then import the images into LrC and will cull again to reduce the number of images down to less than 500. I might keep all of the original images on the scratch disk until I am sure that I have what I need, then delete them. The difference is having backup space for 10,000 images vs 1500 images.
This might seem like extra steps but I have had to rethink how I handle images now that I can shoot high resolution images at 20fps and that doesn't include video.
