Many people want to choose the best SD cards for Canon Rebel T7. What’s the best one? How to format the Canon Rebel T7 memory card for use? What to do if you accidentally delete the video? If you are also trying to figure them out, this post of MiniTool Partition Wizard is what you need.

How to Choose the Best SD Cards for Canon Rebel T7

A memory card for Canon EOS Rebel T7 is a must-have accessory. You won't be able to take many photos or shoot many videos without it. How to choose the best Canon Rebel T7 memory card? Here, we summarize the 4 main factors: type of SD card, storage capacity, read/write speed, and UHS Speed Class.

Type of SD Card

First, the SD card you choose must be compatible with your Canon Rebel T7 camera. For Canon Rebel T7, the following storage types are supported:

  • SD (Secure Digital)
  • SDHC (Secure Digital High Capacity)
  • SDXC (Secure Digital Extended Capacity)

The difference between these three storage types is the capacity. The capacity of the SD is limited to 2GB, the SDHC’s capacity is limited to 32GB, while SDXC’s capacity can be up to 2TB.

Storage Capacity

If you are a professional travel photographer and need to store a lot of large files, storage capacity is the second consideration. Depending on shooting conditions and camera settings, the Canon Rebel can produce approximately 25MB RAW files and 5MB to 13MB JPEG files.

According to investigations, only 276 bracketed photos can be stored on a 32GB memory card. That's not enough storage space for many photographers. Therefore, it is more appropriate to choose a capacity of 64GB or 128GB.

Speed of SD Card

SD card speed should be one of the most critical factors when choosing the best SD card for the Canon Rebel T7 camera. SD card speed includes read speed and write speed.

Write speed is how quickly the camera transfers photos to the memory card, which affects how quickly you can take pictures and the quality of videos. This is critical to allowing photographers to shoot without interruption.

Read speed is the speed at which photos are transferred from a memory card to a computer or other devices, which affects how quickly you can use your computer or camera to view files stored on the card.

So, the write speed of an SD card is also more important for photographers. Well, how to check the write speed of an SD card? Read the part below.

The writing speed of SD memory cards is divided into five grades:

  1. Class 4: Minimum Write Speed 4 MB/s
  2. Class 6: Minimum Write Speed 6 MB/s
  3. Class 10: Minimum Write Speed 10 MB/s
  4. U1: Minimum Write Speed 10 MB/s
  5. U3: Minimum Write Speed 30 MB/s

The Speed Class rating helps you match the card's write speed to the camera's maximum internal speed. According to the survey, the maximum internal speed of the Canon Rebel T7 model is around 30 MB/s. Therefore, the Canon Rebel T7 camera uses an SD card with Speed Class of U3.

Speed Class of U3

UHS Speed Class

The UHS Speed Class rating is another important factor you should consider. It is designed for UHS-equipped devices and specifies a minimum write speed for recorded video. There are 2 levels: UHS-I and UHS-II.

UHS-II cards have new pin connections to maintain the faster bus speed. Both are visible on the back of the SD card: UHS-I cards have one row of pins; UHS-II cards have two rows of pins.

Although UHS-II is excellent in terms of speed, Canon Rebel T7 models do not support the USH-II format, so cannot take advantage of the faster write speeds and will default to UHS-I values.

UHS Speed Class rating

All that said, the best SD memory card for Canon Rebels is an SDXC card, UHS-I type, with a Speed Class of U3.


When buying SD memory cards online, look for brands like SanDisk, Sony, Transcend, Fujifilm, Lexar, Kingston, and PNY. All of them offer reliable products.

How to Format SD Cards for Canon Rebel T7

A new SD card should be formatted before use and periodically thereafter. Which file system should you choose for your SD card? If you want to use it for portable devices like cameras and your SD card type is SDXC, we recommend you format it to exFAT.


If you're formatting a card that you've already used, make sure you've backed up any photos and videos you want to keep, as formatting will delete everything on the card.

It is more thorough and also takes longer. Here we take the standard format.

Step 1:  Insert the memory card into the correct slot and press the Menu button on the camera.

Step 2: Under the Settings 1 tab and select Format Card. Then press SET.

Step 3: Click OK to confirm, and then press SET. The card will be formatted. When the formatting is completed, the menu will reappear.
