Best Memory Cards for Canon EOS Rebel T100
Finding the right storage for your Canon EOS Rebel T100 shouldn’t feel like a technical chore. While this entry-level DSLR is remarkably capable for its price, pairing it with a sluggish card can lead to frustrating “Busy” messages during burst shooting or dropped frames in Full HD video. I’ve tested dozens of SD cards to find the perfect balance of speed and value for the T100’s UHS-I slot. The SanDisk Extreme PRO remains my top recommendation for its unrivaled reliability and snappiness.

Best Memory Cards for Canon EOS Rebel T100: Detailed Reviews
SanDisk Extreme PRO UHS-I View on Amazon View on B&H
The SanDisk Extreme PRO is the gold standard for a reason. Even though the Rebel T100 is an entry-level camera, using a high-quality V30/U3 card like this ensures that the buffer clears as quickly as the camera’s internal processor allows. In my experience, this card significantly reduces the time you’re stuck waiting between burst shots of moving subjects. With read speeds up to 200MB/s, offloading a day’s worth of 18MP RAW files to your computer is incredibly fast. It is shockproof, temperature-proof, and waterproof, which provides immense peace of mind when shooting outdoors. While the T100 cannot utilize the full 200MB/s read speed due to its UHS-I interface limitations, the 90MB/s write speed ensures you’ll never hit a bottleneck while recording 1080p video. It’s a slightly higher investment than basic cards, but the reliability makes it worth every penny for any serious hobbyist.

Lexar Professional 1066x Silver View on Amazon View on B&H
If you want top-tier speeds without the “SanDisk tax,” the Lexar Professional 1066x Silver series is a phenomenal alternative. This card actually offers a faster rated write speed (up to 120MB/s) than the Extreme PRO, which is impressive for this price point. For T100 users, this means effortless Full HD video recording and excellent handling of the camera’s 3 frames-per-second burst mode. I’ve found Lexar’s Silver series to be highly consistent in various weather conditions. It’s rated Class 10, U3, and V30, meaning it guarantees a minimum sustained write speed of 30MB/s—far more than the T100 requires, providing a nice safety margin. The only minor drawback is that Lexar’s long-term reliability reputation has had more fluctuations than SanDisk’s, but the Silver series has proven to be a robust workhorse in my tests. It’s the perfect “middle ground” card for those who shoot both stills and video frequently.

SanDisk Ultra SDXC View on Amazon View on B&H
The SanDisk Ultra is arguably the most popular SD card in the world for casual users, and it suits the Rebel T100 perfectly if you aren’t doing heavy burst photography. It’s incredibly affordable, often priced so low that you can buy two for the price of one premium card. While it lacks the V30 video rating of its “Extreme” siblings, its Class 10/U1 rating is perfectly adequate for the T100’s 1080p video bitrate. You might notice a slight delay if you fire off a long sequence of RAW images, as the write speed is significantly slower than the PRO version. However, for single-shot portraits, landscapes, and standard family videos, you won’t notice a difference in daily use. It’s a reliable, no-frills choice for beginners who want to spend more of their budget on lenses or a camera bag. Just be aware that it isn’t as “future-proof” if you eventually upgrade to a 4K camera.

Kingston Canvas Go! Plus View on Amazon View on B&H
Kingston has really stepped up their game with the Canvas Go! Plus. This card is specifically designed for users on the move, offering V30 speeds that are perfect for the T100’s video modes while maintaining excellent write speeds for action shots. I find this card particularly impressive for its thermal management; it stays cool even during long video recording sessions. The 170MB/s read speed makes it a “Premium” UHS-I card, allowing you to move files to your laptop almost as fast as the SanDisk Extreme PRO. What makes it a premium choice for me is the lifetime warranty and the rigorous testing Kingston puts these through. If you are taking your T100 on a rugged backpacking trip or a humid tropical vacation, this is the card I would trust to keep your memories safe. It’s slightly more expensive than the Lexar, but the build quality is top-tier.

Samsung EVO Select View on Amazon View on B&H
The Samsung EVO Select is unique because it is technically a microSD card that comes with a high-quality SD adapter. For Rebel T100 owners, this offers fantastic versatility. If you ever decide to use the card in a drone, a GoPro, or your smartphone, you can simply pop it out of the adapter. Don’t let the microSD format fool you—this card is U3/V30 rated and incredibly fast. In my testing, it handles the T100’s write requirements without breaking a sweat. Samsung is one of the few companies that manufactures its own flash memory, leading to exceptional quality control. It is waterproof, X-ray proof, and magnetic-proof. While some photographers prefer “full-size” SD cards for peace of mind, the EVO Select with its included adapter is a brilliant, cost-effective way to get high-speed storage that works across all your devices. It’s a smart buy for the multi-device creator.

Frequently Asked Questions
Does the Canon T100 support UHS-II memory cards?
Technically, yes. You can physically insert a UHS-II card into the Rebel T100 and it will function perfectly. However, the camera only has one row of internal pins, meaning it will revert to UHS-I speeds. You won’t see any performance boost while shooting or recording video. The only benefit would be faster transfer speeds when moving photos from the card to your computer, provided you have a UHS-II compatible card reader.
What is the maximum SD card capacity for the Rebel T100?
The Canon T100 is compatible with SD, SDHC, and SDXC formats. This means it can theoretically support cards up to 2TB in size. In practice, I recommend using 64GB or 128GB cards. Using massive cards (like 512GB) can sometimes slow down the camera’s initial startup time as it indexes the files, and it’s generally safer to spread your photos across two smaller cards than one giant one.
How many photos can a 64GB card hold on this camera?
With the T100’s 18-megapixel sensor, a 64GB card is quite spacious. If you shoot in JPEG (Fine), you can fit roughly 8,000 to 10,000 images. If you shoot in RAW—which I highly recommend for better editing—you’ll fit about 2,200 to 2,500 images. For video, 64GB will give you approximately 2.5 to 3 hours of Full HD (1080p) footage at the standard frame rates.
Why does my camera say “Busy” after taking a few photos?
This is usually due to the camera’s buffer filling up. The T100 has a small internal memory that holds shots before writing them to the card. If your SD card has a slow write speed (like an old Class 4 or Class 6 card), the buffer can’t empty fast enough. Upgrading to a V30 or U3 rated card like the SanDisk Extreme PRO will minimize this “Busy” time significantly.
Is it safe to use microSD cards with an adapter in the T100?
Yes, it is perfectly safe. Many modern microSD cards, like the Samsung EVO Select, are just as fast and reliable as their full-sized counterparts. The only “weak point” is the physical adapter itself, which could potentially fail or have loose contacts. As long as you use a high-quality adapter (usually included with the card), you won’t experience any loss in image quality or performance.
Final Verdict
For most Canon Rebel T100 users, the SanDisk Extreme PRO is the smartest investment—it ensures your camera isn’t held back by slow write speeds and offers the best protection for your photos. If you’re on a tight budget, the SanDisk Ultra is a reliable workhorse for everyday snapshots. Travelers should consider the Kingston Canvas Go! Plus for its added durability, while those using multiple gadgets will love the versatility of the Samsung EVO Select.
