Best memory card brands for high-speed shooting on Canon 80D?

Question

I've been pushing my Canon 80D's burst mode lately for wildlife photography, but my current SD cards just can't keep up. The buffer takes ages to clear, and I’m frequently missing action shots because the camera is busy writing data. I know the 80D is technically limited to UHS-I speeds, but I’m wondering if high-end cards like the SanDisk Extreme Pro or a Lexar Professional series would make a noticeable difference in clearing that buffer faster. Reliability is my top priority since I’m terrified of card failure during a shoot. For those of you shooting sports or fast action on the 80D, which specific brands and speeds have given you the smoothest experience?

yo, honestly i get the buffer struggle. i've used my 80D for years and found that the high-end UHS-II cards are kinda overkill since the camera cant use the extra speed anyway. these budget options work well for me: * SanDisk 128GB Extreme PRO SDXC UHS-I Card - usually $20
* Lexar Professional 1066x 64GB SDXC UHS-I Card - about $15 i'm super satisfied with them... never had a single failure yet. cheers!

Tbh, since you’re prioritizing reliability above all else for wildlife, you really gotta look at the data integrity side of things. While the 80D can’t take advantage of UHS-II bus speeds, using a card with a solid V30 rating is still crucial for that buffer clearing. I’ve had great luck with the ProGrade Digital SDXC UHS-I U3 Class 10 V30 cards. They’re founded by former Lexar execs and their QC is honestly way tighter than the generic consumer-grade stuff you find at big box stores. Another solid, ultra-reliable option is the Kingston Canvas Go! Plus SDXC UHS-I. It’s specifically built for durability in harsh conditions, which is perfect if you’re out in the elements for wildlife. One thing to keep in mind—even with a fast card, the 80D's internal buffer is the real bottleneck. Just make sure you aren't shooting RAW+JPEG if you want that buffer to clear faster. Stick to RAW and use a card with a high-quality controller to prevent corruption. It’s sooooo worth the peace of mind so you don't lose a once-in-a-lifetime shot!
