One thing to note with those cards the read speed is 250MB/s whilst the write speed is just 120MB/s. You have to be careful of the write speed as often it’s lower than the stated speed on the card (they often quote the read speed as it sounds much better). Write speed it what matters with the camera. Read speed only matters when you’re transferring the images to the computer.
The price of the fastest UHS-II SD cards can be quite high but there are potential savings depending on brand. I recently picked one of these when they were on offer after someone kindly pointed out the offer on here. It was £60 for a 64GB card at the time. It was cheaper than the SanDisk UHS-ii 300MB/s card I have in the other slot which I think was around £120 at the time I purchased it a few years ago.
I’ve found this to be a good website in the past. It’s not as up to date as it once was but you can see the effect different cards have on write speed with the D500.
