XQD or CFexpress type B

[Peter7100]

Any experience or thoughts on these cards. Both seem to be in a similar price range, so what one would you go for and why?

I assume you mean XQD or CFexpress. My understanding is that CFexpress type B is a newer, faster technology. I rarely see the XQD cards offered for sale anymore, which suggests they are being left behind. On B&H, I see 173 CFexpress cards, but only 2 XQD. The 2 XQD cards are 440 Read and 400 Write running around $140 for 64MB. The Sandisk 64MB CFexpress cards are 1500 Read and 800 Write, and are $110 on sale, with a regular price of $150. To me the CFexpress is the clear winner.

I use CFexpress in my 7ii and 8, and would recommend going with the newer technology.

I use the CFexpress type B in both the D500 and the D850 - Clovishound explains very well above the why

Here in the US XQD were hard to find (when I was shopping)

I ran across this page. It's over a year old, but it gives some real world results on card speeds. It turns out a lot of cards are rated at far higher speeds than this individual's test results. The XQD cards tested were closer to advertised speeds, but still well below most of the CFexpress cards.

so what one would you go for and why?

One thing I remembered noting in reviews was "heating up" during operation - also look for reviews using your camera and a style similar to your desires (such as video/long burst) as it looks to make a difference in reviews I've read

Even with a fast card, I can over run the buffer on my Z8 at 20 fps and RAW. Your 6ii should have less trouble with that since the files are half the size, and max fps is 14. I couldn't easily find the max speed the 6ii will download to the card, as that can sometimes be the bottleneck.

I bought an XQD for my D500 back in the day. It was quite a step up from an SD card back then. The D500 is gone so the XQD is now the backup to the CFExpress Type B in my Z6iii. CFExpress is faster but both cards have been reliable.
