Best Memory Card for Canon EOS 77D
Nothing kills the creative flow like seeing the word “BUSY” flashing in your viewfinder while your Canon EOS 77D struggles to clear its buffer. Whether you are capturing a fast-paced sequence of 24.2MP RAW files or filming a cinematic 1080p vlog at 60fps, your choice of SD card is the silent partner in your photography. After years of testing glass and silicon, I’ve found that the SanDisk Extreme Pro remains the gold standard for this specific mid-range DSLR.

Best Memory Cards for Canon EOS 77D: Detailed Reviews
SanDisk Extreme Pro UHS-I View on Amazon View on B&H
The SanDisk Extreme Pro is the industry benchmark for a reason. While the Canon 77D is limited to UHS-I speeds, this card maximizes that potential. With write speeds hitting up to 90MB/s, it handles the 77D’s 6fps burst rate with ease, ensuring you don’t miss the decisive moment during sports or wildlife shoots. I’ve used these cards in extreme temperatures from humid coastal shoots to freezing mountain tops, and they’ve never once corrupted a file. The V30 rating guarantees that you won’t see dropped frames when recording Full HD 60p video. Its only real drawback is that it’s frequently faked online, so always buy from reputable sources. It’s a “buy once, cry once” piece of kit that offers peace of mind for both enthusiasts and pros using the 77D as a backup body.

Samsung PRO Plus SD View on Amazon View on B&H
Samsung has traditionally dominated the microSD market, but their full-sized SD cards, like the PRO Plus, are phenomenal. For the Canon 77D user, this card represents the sweet spot of value. It offers read speeds up to 180MB/s and write speeds up to 130MB/s, which actually exceeds the SanDisk Extreme Pro on paper. In real-world testing with the 77D, you’ll notice the buffer clears incredibly fast, allowing you to get back to shooting sooner. I particularly like the 7-proof protection (water, temperature, X-ray, etc.), making it a rugged companion for travel photography. It’s slightly less ubiquitous in camera shops than SanDisk, but it delivers modern performance that breathes new life into the 77D’s processing pipeline. It is a fantastic choice if you want 128GB or 256GB of reliable storage without breaking the bank.

SanDisk Ultra SDXC View on Amazon View on B&H
If you primarily use your Canon 77D for family gatherings, vacations, or static subjects where you aren’t firing off bursts of 20 images, the SanDisk Ultra is a perfectly sensible choice. It is significantly cheaper than the Extreme series. While it lacks the V30 video rating (it’s usually Class 10/U1), it can still handle standard 1080p video without much fuss. However, you will feel the limitations if you try to shoot RAW in continuous mode; the camera will stall as the card slowly digests the data. I often recommend this to students who need multiple cards for a project on a tight budget. It’s honest, reliable storage that doesn’t pretend to be professional-grade, but for the average 77D owner taking JPEGs, it gets the job done without any unnecessary bells or whistles.

Lexar Professional 1066x Silver View on Amazon View on B&H
The Lexar 1066x Silver Series is designed for those who want to push their UHS-I cameras to the absolute limit. In the 77D, this card feels incredibly snappy. Lexar has a long history with photographers, and this specific series offers a blend of high durability and consistent throughput. While the 77D doesn’t support UHS-II, this is one of the fastest UHS-I cards available, which is particularly useful when you’re offloading hours of footage to your computer—you’ll save minutes every time you transfer. I find the build quality of Lexar cards to be slightly more rigid than SanDisk, which is reassuring if you’re frequently swapping cards in the field. It’s a premium choice that ensures your hardware is never the bottleneck in your creative process, especially when shooting 14-bit RAW files.

Kingston Canvas Go! Plus View on Amazon View on B&H
Kingston’s Canvas Go! Plus is an underrated gem in the photography world. It is specifically engineered for users on the move, offering great burst-mode performance and 1080p video support that perfectly matches the Canon 77D’s capabilities. With write speeds that hold steady around 90MB/s, it rivals the SanDisk Extreme Pro in almost every metric but often comes in at a lower price point during sales. I’ve found Kingston cards to be extremely resilient to physical wear—the plastic casing doesn’t seem to “chip” at the corners as easily as some other brands after months of use. If you want a reliable alternative to the mainstream SanDisk options, this is a fantastic “set it and forget it” card that will live happily in your 77D for years.

Frequently Asked Questions
Does the Canon 77D support UHS-II cards?
Yes, the Canon 77D is backwards compatible with UHS-II cards. However, the camera hardware is only designed for UHS-I speeds. This means you won’t see any benefit in-camera, such as faster buffer clearing or better video performance. The only advantage is when you take the card out and put it into a UHS-II compatible card reader on your computer; your photos and videos will transfer significantly faster. For most 77D users, UHS-I is the better value.
How many photos can a 128GB card hold on the 77D?
On a 24.2MP sensor like the one in the Canon 77D, a 128GB card is quite spacious. You can expect to fit approximately 4,000 to 5,000 RAW files, or over 15,000 high-quality JPEGs. If you shoot RAW+JPEG simultaneously, that number drops to around 3,000. For video, 128GB allows for roughly 5 hours of Full HD footage at 60fps. It is generally the ideal size for a weekend trip without needing to offload files.
Why does my 77D stop recording video after a few seconds?
This is almost always a “speed class” issue. If your SD card’s write speed is too slow, the camera’s internal buffer fills up and the recording fails. For the 77D’s 1080p 60fps video, you should look for a card with a “V30” or “U3” symbol on the front. These ratings guarantee a minimum sustained write speed that can keep up with the video data stream. Older Class 10 or U1 cards often struggle with high-frame-rate video.
Is it better to use one large card or several smaller ones?
This is an age-old debate among photographers. One 256GB card is convenient, but if it fails, you lose everything. Using two 64GB or 128GB cards is often considered safer; it’s the “don’t put all your eggs in one basket” approach. For the 77D, which only has one card slot, I personally prefer using 128GB cards. They are large enough to be practical but small enough that you’re encouraged to swap and back up more frequently.
Can I use a MicroSD card with an adapter in my 77D?
Technically, yes, you can. However, as an expert, I generally advise against it for primary use. Every connection point (the pins between the microSD and the adapter) is a potential point of failure. Adapters can be flimsy and often cause “Card Error” messages at the worst possible times. If you have a spare microSD from your drone or phone, it works in a pinch, but for reliable photography, stick to full-sized SD cards.
Final Verdict
For the vast majority of Canon EOS 77D users, the SanDisk Extreme Pro 128GB is the logical choice—it’s fast, durable, and perfectly matched to the camera’s specs. If you are a student or on a budget, the Samsung PRO Plus offers nearly identical performance for a lower price. Only step down to the SanDisk Ultra if you are strictly a casual shooter; otherwise, the faster cards will significantly improve your experience during burst shooting and file transfers.
