So I'm not an expert on SD but I have feeling that may be the root of my problem. I recently purchased some previously used SD cards from a Hogger. Shooting with my D850 in CH mode. It takes several shots and stops, The green recording light stays on for an extended period of time. Is it because the cards are not fast enough? They are mostly SanDisk 32 and 64 GB. Thanks
You guessed it! If you have cards with relatively slow write speeds and then fire off a burst, especially in raw, you can fill the buffer and then wait as the camera slowly writes to the offending card. The overall card capacity is irrelevant. You should get much better buffer performance from the XQD/C Express B slot. But the slower SD slot performance will throttle down the faster one.
You might consider pulling the SD card when you are expecting to rattle of a fast burst. Later, when things slow down you can copy raw images from the faster card to the slower one.
Try formatting the cards using the format commsnd in the menu.
SD cards usually have the speed in MB/s printed on the label beside the speed class of the card. For example, 30 MB/s the sped class is a number from 1 to 10 enclosed in the center of the letter C.
The cards compatible with your camera must have a U3 and class 10 rating.
https://www.sdcard.org/developers/sd-standard-overview/speed-class/And as others have mentioned the card would need to be formatted to your device before use. make sure the card is unlocked. Also, you may need to take a pencil eraser to clean the copper contact/leads on the card.
Nikon always lists recommended cards for each of its cameras, and I'll bet the ones you got aren't on it.
D850 files are quite large and it takes a long time to write them to slow SD cards.
Thanks. Y'all. I had formatted the cards. Moving on I feel confident that the card speed is the main issue since I'm shooting jpeg and raw. Problem solved going to us the XQD card for now.p

You can write the raw file to the XQD while writing the JPG to the SD card.
I've never filled the buffer shooting this way, although I don't shoot 50 frame bursts either.

Great advice. I'll start that process

I have purchased used camera equipment in the past. SD cards would not even be a consideration. For exactly the problems you are sadly experiencing.
Older cards can be almost worthless. I have some memory sticks that have such a small amount of memory that they're useless. I prefer new, brand-name SD cards of the proper type. It's too bad that there are so many different specs for memory cards.
Yes! The camera can shoot much faster than the card can write. Try a CF Express (newer tech than the XQD). I do BIF and shoot 5 second bursts with no problem.

Update your firmware and get some faster media. I shoot my D850 E19b batteries many times in 8 to 10 shot bursts with no problem.
Always buy memory cards NEW.
And from a reputable dealer.
Used means not knowing what a card been through or in. May be corrupt or formatted already for a different device.
Different cards have different classes within a brand. Find one that's compatible for the device being used.
