Is there a better SD card I can get, or are these delays normal?

I'm using this card with my Coolpix B600 - https://www.amazon.c...uct/B08GY4K5DS/ I purchased it last July if it makes a difference. 

No problems most of the time, but on long trips, I usually run into a few instances where I have to wait to take a picture, as the camera screen reports that I need to wait for the image or images to finish saving first. Is anything wrong with my card, or are these infrequent delays normal?  Any recommendations for a better, or faster card?  Not a huge deal, but often when birding, I don't have time to wait.

I do follow best practices and format the card after transferring the images each trip.

I think the bottleneck is the camera’s write speed. When you want to get a new card, the Sandisk Extreme PRO is significantly faster, but I don’t think the coolpixes can take advantage of this speed. Ingesting the files from a card reader will be much faster, though.

The DSLRs and mirrorless system cameras won’t stop you shooting completely to clear the buffer as the continuous rate slows when the buffer is nearing capacity.

Ty - since I'm staying with the Coolpix line - just purchased the P1000, I'll just keep my existing card.

I love my USB 3.0 card reader (https://www.amazon.c...uct/B083W6VH1S/) It seems like an order of magnitude faster than my old USB 2.0 reader, also much faster than transferring from the camera directly via USB.  So, maybe if I start coming home with 15,000 pictures instead of 1,500, I'll get a faster card, but I'm fine with the card reader ingestion speed for now, so nothing to purchase.

Choosing the right Sd card is very much important. Sandisk Extreme Pro would be a perfect choice. It has read speeds of 200MB/s and write speeds up to 140MB/s, with a Video Speed Class 30 rating.

I bought a higher capacity version of your suggestion and have been using it for a while.

I figured out the main issue, which is a known problem with the P1000.  In JPG - fine mode, after a burst of 7 shots, there is around a 3.4 second delay before you can take another picture.  In fact, the camera is completely frozen during the delay.  I don't bother with RAW, since after a RAW burst, the delay is > 8 seconds, and when birding, this would be unbearable.  I do, however, sometime encounter further delays, which I'd like some feedback on.  Sometimes, after multiple bursts, there are additional delays in the middle of bursts, with the screen showing something moving, as if it's trying to be the equivalent of a PCs busy cursor icon.  Is this delay caused by my card, or the camera?

Also, when transferring photos form my USB 3.0 card reader to my laptop, I only get speeds between 75-80 MB/s.  Is it normal for transfer speed to be much slower than the advertised write speed for SD cards.

If your USB3 card is plugged into a USB2 slot, you will only get USB2 speeds.  Your laptop may only have USB2 slots.  My desktop has 2 x USB3 slots at the back, and all other slots are USB2.  To take advantage of the faster speed, I must plug into one of the back slots.

Ty - it has USB 3.0 slots.
