I think Karl is right. I bought a computer with a built in card reader when windows 7 came out. I guess the speed of the reading is whatever my computer's bus speed is. I do know that my hard drives can communicate up to 3 Gb (Sata II specs)
Some cards are faster than others. I'm using a Kingston SDXC 64GB 10. I think I look it up on the web to see how fast it is.

Hello all.
I use the full line of Canon 5D cameras…original, 2, 3 and 4.
My most frequently used bodies are the 5DM3 which is 22.3 MP, the 5DM4 is 30.4 MP.
While it’s a nice difference in megapixels it isn’t ginormous, but downloading images from the 5DM4 to my computer (using firewire 800 on a Mac Pro running High Sierra with 32 gigs of RAM) takes ages. I’m using Lexar Pro compact flash cards (UDMA 7, 800x). My hard drive has over a terrabyte of available space on it.
Is this slow process of downloading normal when using these larger megapixel cameras?
Is there a link in my system that can be changed to speed file transfers up?
Thanks for any insight you can offer,
Lea
