Canon Rebel T7i memory cards
A memory card is an essential accessory for the Canon T7i. Without it, you’re not going to be able to take many photos or shoot much video.
But the Canon T7i doesn’t come with an SD card as standard. Some retailers put together bundles of the camera with some accessories. But unless you get one of those, you’re probably going to have to pick up a memory card separately. Or maybe the memory card it came with is too small, and you find it’s filling up too quickly. You don’t want to run out of space when you’re on a trip, so you may want something bigger with larger storage capacity — the cards that are included in bundles are often on the small side and might fill up quickly, especially if you’re on a trip.
So which SD card should you get?
That’s why I’ve put this post together. Hopefully, it’ll save you some time searching, so you can get out shooting sooner and taking full advantage of all the features of your new camera rather than spending your time searching the web and trying to make sense of cryptic technical codes. I’ve been buying and testing numerous SD cards for several years and have put many of the most popular SD cards on the market through their paces. You can find my main SD card tests here, and I have a lot more information on this site about SD cards and other memory cards.
Canon Rebel T7i SD card requirements
The Canon EOS Rebel T7i is a DSLR camera with a 24-megapixel APS-C sensor, with images coming out at 6000 x 4000 pixels (when using the Large setting). And it shoots 1080p60 video.
The Rebel T7i has a single UHS-I SD card slot, and it’s compatible with SDXC, SDHC, and SD cards.
Canon Rebel T7i instruction manual guidance
The Canon T7i’s instruction manual isn’t very helpful in providing guidance on what memory cards work well.
There is a section titled Compatible Cards. This is what it says:
And later (page 39), it says:
You can use an SD, SDHC, or SDXC memory card (sold separately) with the camera. SDHC and SDXC memory cards with UHS-I can also be used. The captured images are recorded onto the card.
That doesn’t clear much up. And it’s certainly not very practical.
So what I’m aiming to do here is provide some practical recommendations on which SD cards to get for the Canon Rebel T7i so that you can spend less time searching online and more time out shooting.
I’m not trying to list every SD card that works in the Canon Rebel T7i–there are others that will work just fine as well. I’m focusing here on ones that offer a good combination of meeting the requirements of all of the T7i’s features, are readily available at major retailers, are cost-effective, and come from major manufacturers with track records for good-quality cards. I’m also basing this on my own SD speed tests.
So here’s more detailed information on these cards, along with some others. Any of these make for a good choice for the Canon EOS Rebel T7i.
These cards are all rated V30 and work well in a very wide variety of cameras, with good versatility for shooting photos and 4K video.
My emphasis here is on cards that meet these criteria:
- They're fast enough for all the features of this camera.
- They're from a reputable and reliable brand, so you can count on them working well.
- They're readily available at major retailers, so you should be able to find them without much trouble.
- They're good value for money, so you're not paying too much for a card that is more than your camera can take full advantage of.
If you want to use a faster, fancier card, you can, but you won't see any extra benefit in doing so while you're operating the camera (but you might see some faster speeds when downloading the photos to a computer, depending on your computer and memory card reader combination). And, as always, I recommend buying from a major retailer to minimize the chances of getting burned with a counterfeit memory card.
SanDisk Extreme V30 UHS-I
- Type: SDXC / SDHC
- Video Speed Class: V30
- UHS Bus Interface Type: UHS-I
- Maximum Read Speed: 230 MB/s
- Storage Capacities: 32GB, 64GB, 128GB, 256GB, 512GB
Check current price and availability at:
SanDisk's Extreme range are good bets for many cameras, and that's true here too. SanDisk has faster ranges, like the Extreme Pro line, but this Extreme line is both quick enough for most cameras and usually less expensive than those faster cards.
One thing to note with SanDisk cards is that they recycle their model names. So you can find Extreme cards that are older and slower. You'll probably find those older versions work just fine — it really depends how far back you go. I've used many SanDisk Extreme cards over the years in many different cameras and have found them to be very reliable. They're also often good value, and you can sometimes find them sold in 2-packs (it's always good to have a spare on hand!).
Lexar High-Performance 800x PRO BLUE Series V30 UHS-I
- Video Speed Class: V30
- UHS Bus Interface Type: UHS-I
- Maximum Read Speed: 150 MB/s
- Storage Capacities: 64GB, 128GB, 256GB
Check current price and availability at:
The Lexar 800x Pro range is a relatively new model that replaces the old 633x cards that were mainstays of Lexar's SD cards for a long time. This newer V30 card is still a good combination of speed, reliability, and value, and you can often find them in multipacks to have spares on hand.
Delkin Devices ADVANTAGE V30 UHS-I SDXC (180 MB/s)
- Type: SDXC
- Video Speed Class: V30
- UHS Bus Interface Type: UHS-I
- Maximum Read Speed: Up to 180 MB/s
- Storage Capacities: 128GB, 256GB, 512GB, 1TB
Check current price and availability at:
Delkin Devices have recently come out with a range of new SD cards of varying speeds and specs. This is one of their mid-range cards that is rated for V30 video recording speeds. This newer version is rated for read speeds of up to 180 MB/s (the older version of the Advantage maxxed out at 90 MB/s).
Nextorage Classic V30 UHS-I SDXC Card
- Type: SDXC
- Video Speed Class: V30
- UHS Bus Interface Type: UHS-I
- Maximum Read Speed: Up to 200 MB/s

Making sense of SD card specifications
There are several types of SD card, and you’ll find a range of different acronyms and codes on them. Here’s a quick overview of what to look for.
What is the difference between SDXC and SDHC
Most of the cards you’ll see available now have either SDHC or SDXC printed on them. The Canon Rebel T7i will work with both SDHC and SDXC cards (and, for that matter, just plain SD cards, but they’re hard to find these days and have impractically small storage capacities).
These aren’t performance categories, as such. An SDXC card isn’t necessarily any faster than an SDHC card, and vice versa. But they’re important for compatibility with the camera and also in terms of storage capacity.
They’re categories assigned by the SD Association, which is the organization that oversees and develops the standards for SD and microSD cards. The difference between those two specifications is in the filesystem they’re formatted with–the SDHC specification uses FAT32 formatting, while the SDXC specification uses exFAT–but when it comes to buying memory cards, the practical difference is that cards 32GB and smaller will be labeled SDHC and cards 64GB and larger will be labeled SDXC.
And in the Canon T7i, that has one important practical consideration beyond the obvious one of storage size. The T7i detects whether the card is exFAT or FAT32. For cards that are formatted with FAT32, it will break up long videos and save them into 4GB chunks–4GB is the largest file size supported by FAT32. You’ll then need to join them back together in post-processing. But exFAT can support files exponentially larger.1 So when using an SDXC card formatted with exFAT, the camera won’t need to break up the files and will instead save it as a single uninterrupted file.
UHS-I vs. UHS-II
The current generations of SD cards also have UHS-I or UHS-II on them (or often just an I or II). This refers to the type of interface that’s used to connect to the cards. It stands for ultra-high-speed bus.
Aside from whatever is printed on the card or packaging, you can tell UHS-I and UHS-II cards apart just by looking at them. UHS-I cards have a single row of contacts on the back. UHS-II cards have a second row of contacts.
UHS-I is the older, simpler bus interface. UHS-II is newer and potentially faster. The catch is that you only get the extra benefit of UHS-II if the device is also UHS-II. But the spec is designed to be backward compatible, so you can use UHS-II cards in UHS-I devices, but you will only get the speed of UHS-I.
The Canon Rebel T7i doesn’t have a UHS-II interface, so, as a practical matter, there’s no benefit to using UHS-II cards in it (but it’s perfectly fine to do so if you already have a UHS-II card on hand).
Video Speed Classes
The SD Association has come out with various rating systems over the years to help buyers choose a card that’s suitable for use in cameras. Because recording high-resolution video (or, more specifically, high-bitrate video) is often the most demanding operation in terms of a camera and its memory card, it’s known as a video speed class rating system.
As a technical matter, the first system was known Speed Classes (these were Class 2, 4, 6, and 10). The second system was known as UHS Speed Classes (U1 and U3). The third system is known as Video Speed Classes (V6, V10, V30, V60, and V90).
Most cards available now have a mix of old and new speed class codes printed on them. And while it’s helpful, it’s still an imperfect system for judging the speed of an SD card.
As a practical matter in the Canon Rebel T7i, cards that have any of these on them should be fast enough:
- V30
- V60
- U3
SD cards with a V90 rating will also work–the system is designed to be backward compatible like that–but they’re overkill for the Canon T7i.
There’s a separate rating system that you might also see on some cards. They might have an A1 or A2 on them. You can ignore that when choosing an SD card for a camera. It’s designed for the kinds of operations that gaming devices and smartphones do.
So why get a good memory card?
A better memory card is not going to help you take better photos or improve image quality. But it can let you take advantage of all of the camera’s features. A card that’s not fast enough to keep up with the camera can cause issues like locking up, dropping frames, and overheating.
There’s also the issue of reliability. There are plenty of junk memory cards on the market. Not only do they have flaky performance, but they’re also more likely to fail. And that means the risk of losing your photos and videos.
At the same time, you don’t want to pay extra for a high-performance SD card that’s overkill for the camera.
How to format SD cards
When you buy a new SD card, you should format it before use and then regularly after that. If you’re formatting a card that you’ve already been using, make sure that you’ve downloaded any photos and videos you want to keep, because formatting deletes everything on the card.
Here’s some information on how to format the memory card.
How to format SD cards in the Canon Rebel T7i
It is best practice to always format memory cards in the camera that you’ll be using them in. That sets the card up with the filesystem, folder hierarchy, and, in some cameras, a database file, so that the card is just how the camera expects. That greatly reduces the risk of unexpected errors and unpleasant surprises.
Always be sure you’ve backed up everything you want from the card, because formatting it will wipe everything. (If you’ve formatted accidentally, it still might be possible to recover data from the memory card, but it’s not always guaranteed, and it can incur the expense of buying recovery software; more on that below.)
On the Canon Rebel T7i, you can find the format function under:
Wrench icon 1 > Format Card > SetThe T7i also has a low-level format function. That’s a more thorough and secure process, but it also takes significantly longer. If you’re disposing of the SD card or lending the camera to someone else, it provides a safer option that vastly reduces the chances that anyone could recovery anything from it (at least with the normal data recovery tools available to consumers).
How to format SD cards with a computer
Having said that, it is still possible to format memory cards using a card reader and computer. You get a lot more flexibility that way, but also some extra risk if things aren’t set up just how the camera wants them. It’s also sometimes a good troubleshooting step if you’re having issues with a memory card.
There are some things to watch out for, particularly when it comes to choosing which filesystem to use. So I’ve put together guides on how to format SD cards on Mac and how to use the free SD Card Formatter app for Windows or Mac.
FAQs about Canon Rebel T7i SD cards
What SD card does the Canon Rebel T7i use?
The Canon EOS Rebel T7i DSLR is compatible with SDXC and SDHC memory cards. It’s compatible with SD cards with storage capacities ranging from 4GB up to 1TB (the maximum currently available in consumer SD cards). For best performance, an SD card that is fast enough to handle the T7i II’s high-bitrate video recording is recommended.
Does the Rebel Canon T7i come with a memory card?
The Canon T7i doesn’t come with a memory card as standard. Some retailers might put together a special deal bundle that includes some accessories, but in general, you’ll have to buy the memory card separately.
Notes & References:
- The practical maximum file size supported by exFAT is 128 petabytes. In theory, it can go up to 16 exabytes, but that exceeds the maximum partition size, so it’s not possible to do in practice. [↩︎]
