memory card speeds

If the camera uses two cards - should the cards' read/write speeds match or does it not make a difference?
Camera is Nikon D850 & D810

I have a Lumix G9, it has two slots and they recommend two exact cards

I am not sure about the 850 Howard, but in the D500, there are also 2 slots but the first is for a QXD card which is much faster than any SD card, so I think it is camera specific. In any case the faster the better.

Are you doing RAW to both, or splitting RAW and Jpeg?

I will suggest the specific Camera model's Owners Manual, should have that Memory Card specifications.

I always use two of the same speed. chase

I don't believe my manual weighs in on this issue, at least I haven't found it yet in 476 pages.

Good answer and reference - pick the memory card that benchmarks at the highest speed for YOUR camera and fits in your budget.

I like that you mentioned the capabilities of the camera merits consideration.I can put 150mph rated tires on my car, but it won't go any faster than it did before.

They don't have to match. The fastest card should be doing video and/or RAW. The slower card can do the JPEG files just fine.
I normally do JPEG to a slower card without any problem. If you are doing sports where you use Continuous High speed, you need a fast card. Otherwise no problem.

If the manual doesn't specify, I wouldn't worry about it at all. The software will transfer accordingly to the card speed as there is hand shaking to indicate (to the camera) the process is completed.
Slow cards don't miss/loose data, they just take a bit longer to transfer the data.
If there was a speed problem, slow cards would not work, but they do.

Kind'a what I was thinking, neither manual mentions any necessary matching.

Also, the camera most likely has only one processor, which means that it probably sends to one card THEN the other card. I can see NO conceivable reason for them to write code to multiplex the transfer (some to A, then some to B, then some more to A, ....). All data is transferred internally on [i]one[[/i] data bus, cards cannot be written simultaneously.

It'll take a lot longer to write a RAW file, so if you're writing jpeg to one and RAW to another...write speed varies with the type and size being written to each card.
