Best Memory Cards for Canon EOS 77D
The Canon EOS 77D remains a fantastic “bridge” DSLR for enthusiasts, blending entry-level ease with pro-sumer features like the top-plate LCD. However, to truly harness its 6fps burst rate and 1080/60p video, your storage can’t be an afterthought. Using a sluggish card will lead to frustrating buffer hangs just when the action gets good. I’ve tested dozens of SD cards, and for the 77D, the SanDisk Extreme Pro is the undisputed champion for reliability and speed.

Best Memory Cards for Canon EOS 77D: Detailed Reviews
SanDisk Extreme Pro UHS-I View on Amazon View on B&H
If you want the absolute best for your 77D, look no further than the SanDisk Extreme Pro. While the 77D only supports UHS-I speeds, this card pushes that interface to its absolute limit. With shot speeds up to 140MB/s, you’ll rarely find yourself waiting for the buffer to clear after a burst of RAW shots. I find this card particularly essential when shooting sports or wildlife; it ensures that the camera’s 45-point AF system isn’t held back by slow storage. It’s also V30 rated, which is more than enough for the 77D’s 1080p 60fps video. The only real “downside” is that the 200MB/s read speeds require a specific SanDisk reader to achieve on your PC, but even with a standard reader, it’s incredibly fast. It is rugged, shockproof, and temperature-proof, making it a “buy it once” solution for your camera bag.

Samsung PRO Plus View on Amazon View on B&H
Samsung’s PRO Plus line has become a serious contender in the SD card market, often undercutting SanDisk on price while offering comparable real-world performance. For the Canon 77D user, this card provides a seamless experience. It easily handles the camera’s maximum bitrates for video and provides quick enough write speeds to keep your continuous shooting fluid. What I personally love about Samsung cards is their “7-proof” protection—they are remarkably resilient against water, magnets, and even X-rays. If you’re a travel photographer taking your 77D through airports and various climates, that peace of mind is worth every penny. It might not hit the absolute peak write speeds of the Extreme Pro in benchmark tests, but in a mid-range DSLR like the 77D, you’d be hard-pressed to notice the difference during a typical day of shooting. It’s the smart choice for value-seekers.

SanDisk Ultra SDXC View on Amazon View on B&H
The SanDisk Ultra is the “old reliable” for anyone who doesn’t need professional-grade speed. If you primarily use your Canon 77D for family gatherings, vacation snapshots, or stationary portraits, you really don’t need to spend extra on the Extreme line. The Ultra handles 1080p video just fine, though it lacks the V30 rating of its more expensive siblings. The trade-off here is the write speed; if you hold down the shutter for a long burst of RAW photos, the camera will pause longer to “breathe” while it writes data to the card. I wouldn’t recommend this for a wedding or a fast-paced football game, but for everyday use, it’s more than adequate. It’s also an excellent choice for a secondary “backup” card to keep in your wallet. Just be aware that it’s not designed for heavy-duty video work or high-speed action photography.

Lexar Professional 1066x Silver View on Amazon View on B&H
The Lexar Professional 1066x Silver series is a powerhouse specifically designed for those who push their UHS-I cameras to the limit. For the 77D, this card offers a very consistent experience, particularly when shooting in RAW+JPEG mode, which generates quite a bit of data per click. In my testing, Lexar cards have a very “steady” write speed, meaning you don’t see the sudden dips that cheaper cards sometimes exhibit. This makes it a great choice for long-form video recording where a drop in speed could theoretically cause a recording to stop. It’s a slightly more “pro” feeling card than the Samsung, and it often comes with a limited lifetime warranty, which is a nice touch for those who rely on their gear for paid gigs. If you’re planning on upgrading to a newer camera soon but want a card that performs perfectly in your 77D today, this is a top-tier contender.

Kingston Canvas Go! Plus View on Amazon View on B&H
Kingston is often overlooked by photographers, but their Canvas Go! Plus series is surprisingly robust. It hits those crucial V30 and U3 speed classes that ensure your 77D’s video never stutters. I’ve found these cards to be particularly reliable in terms of file system integrity; I’ve never had a corrupted file with a Kingston card in several years of light use. While it doesn’t boast the flashy 200MB/s marketing numbers of the SanDisk Extreme Pro, its real-world write speeds are very competitive. It’s an “also great” choice because it’s frequently on sale, often making it the cheapest high-performance card from a major brand. If you find this for a few dollars less than the Samsung or SanDisk, don’t hesitate to grab it. It’s a workhorse that gets the job done without any unnecessary flair, fitting perfectly into the 77D’s enthusiast workflow.

Frequently Asked Questions
Does the Canon 77D support UHS-II memory cards?
Yes, the Canon 77D is backward compatible with UHS-II cards, so they will function perfectly fine in the camera. However, because the 77D’s hardware is designed for the UHS-I interface, you will not experience the higher UHS-II speeds while taking photos or recording video. The only benefit you’ll gain is faster file transfers from the card to your computer, provided you use a dedicated UHS-II card reader. For most users, high-end UHS-I cards are a better value.
What is the maximum SD card capacity for the 77D?
The Canon EOS 77D supports SDXC (Secure Digital eXtended Capacity) cards, which theoretically allows for capacities up to 2TB. In practical terms, cards up to 512GB and 1TB are readily available and work perfectly. However, I generally recommend using multiple 128GB cards rather than one massive card. This strategy minimizes the risk; if one card fails or gets lost, you haven’t lost your entire shoot’s worth of data. 128GB holds roughly 3,000 RAW files.
Can I record 4K video on the 77D with these cards?
The Canon EOS 77D does not actually support 4K video recording; its maximum resolution is 1080p (Full HD) at 60 frames per second. Because of this, you don’t need the ultra-high-speed V60 or V90 cards required for 4K cinema cameras. Any card labeled V30 or U3 will easily handle the maximum video bitrate of the 77D. Using a V30 card like the SanDisk Extreme Pro ensures that you won’t encounter any “Recording has been stopped automatically” errors.
How many photos can a 64GB card hold on the 77D?
With the 77D’s 24.2-megapixel sensor, a 64GB card will hold approximately 1,500 to 1,800 RAW files, or over 6,000 high-quality JPEGs. If you shoot in “RAW + JPEG” mode, that number drops to about 1,200 images. For most hobbyist photographers, 64GB is a perfect amount for a full day of shooting. If you are traveling or shooting video alongside photos, upgrading to 128GB provides a comfortable buffer so you don’t have to delete files in the field.
Why is my camera’s “busy” light staying on for so long?
If the red access light on your 77D stays on for several seconds after you stop shooting, it means your memory card’s write speed is too slow to keep up with the camera’s buffer. This is common when using “Budget” or older Class 10 cards during burst shooting. Upgrading to a card with a higher write speed, like the SanDisk Extreme Pro or Lexar 1066x, will drastically reduce this wait time, allowing you to review your images and resume shooting almost instantly.
Final Verdict
For the majority of Canon EOS 77D users, the SanDisk Extreme Pro 128GB is the smartest investment you can make to ensure your camera never skips a beat. If you’re a student or a casual shooter on a budget, the Samsung PRO Plus offers nearly identical real-world performance for less. Avoid the no-name “bargain” cards at all costs—your memories are worth the few extra dollars for a reputable brand that won’t fail when the perfect shot happens.
