Same setup here, love it

Same boat, watching this

Just saw this thread and honestly you should check out some of the real-world benchmark sites like Camera Memory Speed or The-Digital-Picture because they show how these cards actually perform in-camera which is way different than the label speeds sometimes!! I've been doing some market research for my own kit and there are some newer players that are realy shaking things up in terms of value. Here's how I'd break down the current market: 1. Kingston Canvas React Plus V90 SDXC - Pros: Honestly the best bang for your buck for V90 speeds. Cons: Can be a bit harder to find in local shops sometimes. It's great for those crazy 40fps electronic shutter bursts where you're just spraying and praying lol. 2. ProGrade Digital SDXC UHS-II V60 Gold - Pros: Pro-grade reliability and they have great firmware. Cons: V60 means you might hit a buffer limit on the longest bursts but it's perfect for 4K video stuff. TL;DR: Go Kingston if you want V90 speed for V60 prices, or ProGrade Gold if you want a super stable workhorse for video and dont need the absolute fastest burst clearing. Definately check the benchmarks before buying though!

Quickly adding my two cents while I am waiting for some files to export! I spent way too much time obsessing over this when I first got into the RF system. I eventually realized that the max speed on the label is mostly marketing fluff and what actually matters is the sustained write speed for those heavy bursts. I personally swear by ProGrade Digital SDXC UHS-II V60 Gold cards because they hit that perfect balance. I have been pushing them hard with 4K60 video and they havent stuttered once! If you really want to go overkill for peace of mind during fast action, I found that Delkin Devices Power SDXC UHS-II V90 is an absolute beast for clearing the buffer. The V60 rating is usually plenty for the R6 Mark III video bitrates tho, and you save a ton of cash. My DIY tests showed that these cards stay cooler during long video takes compared to some of the generic cards I used to use. Just make sure you get a decent UHS-II reader too or you will be waiting forever at your desk to see your shots...

Oh, that's awesome you're getting the R6 Mark III! It's a seriously impressive camera, and yeah, your old cards might struggle a bit, especially with that 4K video and fast bursts. I totally get wanting to avoid buffer issues – it's the worst when you miss a shot because your card can't keep up!

For your situation, I would definitely suggest going for UHS-II cards. While V90 is the absolute fastest, it's often overkill and way more expensive. For the R6 Mark III, a good V60 or even a solid V30 UHS-II card should be more than enough to handle most things without breaking the bank.

I've had great luck with cards from Sony SF-M Tough Series 128GB UHS-II SDXC Memory Card and Lexar Professional 2000x 128GB SDXC UHS-II Card. They're both V60 rated and have handled my 4K video and rapid-fire stills like a champ. I actually used the Sony card for a whole wedding shoot and didn't experience any buffering at all, even when I was trying to capture multiple shots in quick succession during the ceremony. The Lexar is a bit quicker on the transfer speeds when you get the files off the card, which is a nice bonus too!

Honestly, I think a 128GB or 256GB card is a good sweet spot for capacity and price. You get plenty of room for a good amount of photos and video, and they're not outrageously expensive. Just make sure whatever you choose explicitly states UHS-II compatibility. That's the key for the speed you'll need.

Hope this helps and happy shooting with your new R6 Mark III!

Hey there! Oh man, congrats on the R6 Mark III, that's gonna be a beast! Totally get wanting to get the right cards for it. I've been through this myself with my cameras, and trust me, you don't want to be fighting buffer issues when you're trying to nail that shot or capture smooth 4K.

For your R6 Mark III, especially with 4K video and fast burst shooting, you're definitely going to want UHS-II cards. The V90 rating is ideal for the absolute highest bitrates, but honestly, for most users, including myself, a good V60 or even a high-end V30 can work well if you're not pushing the absolute limits of recording all the time. However, since you're getting the Mark III and want to avoid any bottlenecks, I'd lean towards V60 or V90.

I've had really good luck with SanDisk Extreme PRO SDXC UHS-II V90 300MB/s cards. They're a bit pricier, but the speed and reliability are top-notch. For a slightly more budget-friendly but still excellent option, I've also found Lexar Professional 2000x SDXC UHS-II V60 300MB/s to be super consistent. Just make sure whatever you pick, it explicitly states UHS-II compatibility and a high speed class like V60 or V90. It makes a HUGE difference, especially for video. Hope this helps you find the perfect cards!

Here's what I recommend for your R6 Mark III, focusing on getting the best bang for your buck without overspending! For that camera, especially with 4K video and fast bursts, you're definitely going to want UHS-II cards. V90 is the top tier, but honestly, for most situations, a good V60 or even some faster V30 cards can work really well and save you some cash.

I've been really happy with SanDisk Extreme PRO 128GB SDXC UHS-II V60 cards. They offer a fantastic balance of speed and reliability. I use them for my own video work, and I've never had a buffer issue or dropped frames, even with some demanding footage. They're usually priced pretty reasonably, especially when you find them on sale.

If you're shooting *really* long 4K clips or doing extreme burst sequences constantly, then a V90 might be worth considering, but honestly, it’s often overkill and significantly more expensive. For most users, a reliable V60 like the SanDisk Extreme PRO should be more than enough. Just make sure to buy from reputable sellers to avoid fakes! Hope this helps get you sorted!
