No buffer problems with 45mb cards. I use the Delkin USB 3.0 Memory Card Reader model DDREADER42 for $36.95 it reads every card made. Works with both USB2 and USB3 (You can just use the camera as well)
Typically CF cards are faster due to containing it's own memory management circuits, whereas it is better to use the SD for video because the camera manages the memory and it is more efficient for video than the CF.
I use both, sized the same and in the backup mode. It gives me piece of mind for weddings. I get 800 RAW shots on my 64GB using lossless compression.
You do want a CF that is UDMA capable, otherwise the buffer could be impacted. For SD cards, make sure to get a Class 6 or Class 10 for video performance. I have read suggestions for 30MB/Sec or faster and Class 10 for SD cards.
I use the following: SanDisk Extreme Pro® SDXC™ UHS-I Memory Card (95MB/S, Class 10) 64GB # SDSDXPA-064G
I see no performance difference between the Extreme Pro and Extreme. I am sure there would be a slight difference when the buffer fills, since the Extreme Pro should write faster, hence clear the buffer faster.
In reply to the OP, no you would not be losing out if you only purchase the SD card, except you will not have overflow, or backup selections to make. You can even go with the slower 45MB/S SD (Sandisc Extreme versus the Extreme Pro) and purchase a higher MB card for the same price and not have any issues as well.
As I state above, I use my SD/CF for backup peace of mind. I typically leave the CF card in the camera and only transfer the contents of the SD card to my computer. After those images are redundantly backed up and verified, I then format both cards in the camera. I have yet to have a problem with the SD card. The other nice thing about having two cards being used in the backup mode is if you accidentally erase the photo, you still have it on the backup card.
