XQD of 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.
