    • Perfect Match for My Canon DSLR
Capacity: 32GB Style: Memory Card Only
This card is a workhorse. Popped it into my Canon DSLR, and it hasn’t hiccupped once. Shooting RAW, rapid bursts, and 1080p video all work flawlessly. The speed is exactly what you need if you don’t want your camera to choke during action shots. I trust SanDisk more than any off-brand card, and this one lives up to its “Extreme PRO” name. Rugged, reliable, and plenty of space for long shoots without swapping cards every 20 minutes. Highly recommend for anyone serious about photography. ... show more

    • Typical solid SanDisk quality
Capacity: 128GB Style: Memory Card Only
Genuine as far I can tell. Speed ratings are good with speedy downloads and uploads and works perfectly on my camera. Never had issues with data loss with SanDisk memory in the decades I’ve used them for photography. I’ve used a lot of other brands as well and honestly never had issues with any of them but if you find a good price on SanDisk, it’s a no brainer. ... show more

    • Fast, reliable, and plenty of space
Capacity: 256GB Style: Memory Card Only
This SD card works perfectly with my Canon R50, even when shooting 4K video. The speed is excellent, with fast write and transfer times, so I never worry about lag or dropped frames. It handles burst shooting and large RAW files without any issues. The 256GB capacity is a huge plus, giving me tons of space for both video and high-resolution photos without needing to swap cards constantly. I’ve used SanDisk cards for years and they’ve always been reliable. Definitely worth the price for the performance and peace of mind. ... show more

    • Great cards for landscape and street photography
Capacity: 64GB Style: Memory Card Only
Review Image by Heidi Heidi
SanDisk Extreme Pro 64GB SD Cards – These cards are absolutely fantastic! Perfect for daily photography, travel, and vacations. I personally prefer using multiple smaller cards instead of one huge one—why risk putting all your eggs in one basket? This way, each day’s adventures are safely stored, and if something ever goes wrong, I don’t lose everything at once. For the cost, these are a no-brainer backup solution for protecting those irreplaceable memories. When traveling off the grid, I’ll pop in a new card each day—it gives me incredible peace of mind knowing my photos are safe even if it’s a few days before I can upload them. And let me say, these Extreme Pro cards can take a beating! They’ve handled high humidity, rough travel conditions, and multiple airport security scans without skipping a beat. Fast enough unless your shooting burst mode or video, super reliable, and built tough—SanDisk Extreme Pro is hands-down my go-to memory card for every adventure! ... show more
