UHS-II suggestions to maximize slot 1

**jerryleejr** · 04-24-2021, 12:02 PM

Seeing as how the dual card slot support different speeds, anyone gonna mix and match? I’ve had no bottlenecks with UHS I with my other bodies. And I tend to shoot RAW to card one and jpeg to card 2. I would think one would only need the faster speed handling the video...

I would think a v90 card would clear the buffer faster.

How many of your other bodies shoot 12 fps? You’re going to have bottlenecks here. I experimented a little bit this morning with a UHS-I card in slot 1, and I was able to shoot a burst around the maximum size, but it took forever to clear compared to with my new UHS-II card in there. I tried DNG to slot 1 and JPEG to slot 2, and it was super slow to get the buffer cleared. If you’re not shooting maximum length bursts or 20-ish image bursts in someone rapid succession, then you can do fine without UHS-II cards. But for sports and I’d say for wildlife subjects like BIF, you want a UHS-II card and to just use slot 2 to hold your second card so that you can put it into slot 1 when your first card is full.

I just shot over 1500 frames today and the UHSII clears the buffer faster as you would expect. I shot all in RAW and when the first card filled the only difference I noticed was the buffer fills faster. At 12fps the card fill fast! I'll seldom need all that speed.

Thanks,
I missed those on my initial search..

I shoot in burst mode a lot. A lot lot. And one of my frustrations is waiting for the buffer to clear.

So if anyone might suggest an SD card or two that will maximize that first slot in a new K3 iii, I'd be grateful.

Buy the fastest card you can find, but be aware that doing so may not improve the write times from buffer. One thing is for sure. It certainly can't hurt.

V90 speed is the highest - pay attention to the write speeds of the cards, faster is better for buffer clearing

**ProfessorBuzz** · 04-30-2021, 05:26 AM

I've had good luck with Lexar Professional 150MB/s 1000x SD XC Class 10 UHS II 3. I supect there are faster cards available now, but I've used these for a few years with great results.

Thanks so much for the replies. I think, for now (after having read a number of threads here and elsewhere), I'm going to go with the Kingston React Plus. It's a v90 that's supposed to have very fast write speed as well as be very reliable. I've shot SanDisk nearly exclusively for a while and liked those. But the price point and performance on the Kingston makes the most sense to me for this purchase. Can't wait to see how the combo does!

Good choice.

I checked the read and write speeds, prices, and availability of the SanDisk Extreme Pro UHS-II and decided that is the way I am going to go. I'm not going to cheap out and buy a slower version of SD card or a knock off brand after forking over the big bucks for the K-3iii in the first place.

And that's my other set of 4 cards. Another good choice

That's the card I bought as a discounted bundle when I preordered my K-3 III
