How to save everything to a memory card on Xiaomi Redmi: the complete guide

Xiaomi and Redmi smartphone owners often face a lack of built-in storage, especially in budget models with a capacity of 32 or 64 gigabytes. MIUI system, being quite heavy, quickly eats up the available space, and installing modern applications and games only exacerbates the problem.

Many users mistakenly believe that it is enough to simply insert the drive into the slot, and the system will automatically start writing all new data there. However, in modern versions of Android and the MIUI shell, the process requires manual adjustment to fully integrate flash memory.

In this article, we will discuss in detail all the stages of preparing, formatting and optimizing work with an external drive on Xiaomi devices. You will learn how to turn a regular flash drive into a full-fledged continuation of internal memory, while avoiding common mistakes that can lead to data loss or reduced performance of the gadget.

Choosing the Right Memory Card for Xiaomi

The first and critical step is to choose a quality storage medium: the speed of reading and writing data directly affects the performance of a smartphone, especially if you plan to run applications from a memory card. Cheap models of nameless brands often do not meet the declared characteristics and can cause malfunctions in the Android system.

Pay attention to the speed class, which is marked with a number inside the letter U or just a number. For modern smartphones, the minimum acceptable standard is Class 10, however, for comfortable work with heavy games and shooting video in 4K, it is recommended to choose the UHS-I or UHS-II standards. Using a slow card will make the phone interface “reflective”, and downloading applications will take an unreasonable amount of time.

Also consider the maximum volume supported by your phone model. Although many modern Redmi devices claim support for cards up to 512 GB or even 1 TB, older models can only work correctly with drives up to 128 GB. Before buying an expensive volume, be sure to check the specification of a particular device on the official website of the manufacturer.

⚠️ Warning: When buying memory cards on popular marketplaces, beware of fakes. 256 GB and above at suspiciously low price often real volume 8-16 GB, which will lead to cyclical overwriting and file loss.

• 🚀 Choose cards with markings A1 or A2 fast-tracking.
• 💾 Optimal volume for multimedia – from 64 to 128 GB, for games – from 256 GB.
• 🏷️ Give preference to proven brands: SanDisk, Samsung, Kingston, Lexar.

Physical Installation and Primary Formatting

After purchasing the right drive, you need to install it correctly. In most models Xiaomi and Redmi trays for the storage of the device. SIM-The card is combined with a microSD slot. Be extremely careful when removing the tray, using a special clip so as not to damage the mechanism or neighboring contacts.

Put the memory card down with metal contacts, making sure it fits tightly against the tray wall. Once turned on, the smartphone must automatically identify the new media and suggest options for its use. At this stage, the system will offer two ways: use the card as a portable storage or as part of internal memory.

If you want to store only photos and music, choose portable storage, but to solve the problem of space shortage, we need the second option. When choosing the mode "Internal memory" (or "Advanced memory"), the system will require formatting the drive. All data previously on the map will be irretrievably deleted, so save important information on the computer in advance.

The formatting process can take from a few minutes to half an hour depending on the volume and speed of the card, and it is absolutely impossible to interrupt this process, as this can damage the file system and prevent further use of the drive.

Setting up a map as the main storage

In modern versions of the MIUI shell, the full-featured integration of internal and external memory is sometimes hidden or not as clearly implemented as in pure Android. After initial settings in the Settings → Memory menu, you need to make sure that the card is recognized correctly.

Forced data transfer often requires activation of special developer modes or use of third-party utilities if standard functionality does not allow to move all applications, however, in most cases, it is enough to select the item "Use as internal storage" in the memory management menu.

Once this mode is activated, the system begins to encrypt the memory card by linking it to a particular device, which means that you can't simply move the flash drive to another phone and read the data without formatting, a security measure that protects your personal information from unauthorized access.

💡

If the phone’s speed has dropped after formatting, it’s possible that your memory card’s speed class is too low to function as a system partition.

Transfer of applications and games to SD-map

One of the main goals of memory expansion is the ability to install heavy games and applications. Not all programs support porting to an external drive due to Android security limitations, but many can be moved manually through settings.

Go to the Settings menu → Annexes → All applications. Select the program you want, find Memory or Storage. If you can transfer, the Move to button will be active. SD-Once the process is complete, the main part of the application body will take up space on the external media, freeing up internal memory.

It is worth noting that the cache of some applications (such as maps or messengers) can take up a significant amount of space, and it often requires additional actions or use of functions within the applications themselves to change the way data is stored.

• 📱 Only carry heavy games and rarely used apps.
• ⚡ System services and frequently used messengers are best left in internal memory.
• 🔄 After the transfer, restart the device to display the changes correctly.

Automatically save photos and videos from the camera

For most users, photos and videos are the main memory, and Xiaomi’s camera saves media files to internal memory by default, but this setting is easy to change, allowing you to take pictures without constant notifications about space shortages.

Open the Camera app, click on the menu icon (three stripes or gears) in the upper right corner. SD-Map or Save Way and activate the switch, from now on, all new images and videos will be automatically recorded to an external drive.

To move them, use the standard MIUI Explorer or Gallery app. Select the albums you want, select Move, and specify the corresponding folder on the memory card.

⚠️ Attention: When recording high-resolution video (4K 60fps) The speed of the card may not be enough, in which case the recording will be interrupted, even if the checkmark saves on the card. SD. For 4K Videos are better used for internal memory.

Optimization of messengers and downloads

Messengers like Telegram, WhatsApp and Viber tend to grow to giant sizes. Each of them has a way to save downloadable files. Telegram does this through Settings → Data and Memory → The Data Path.

Browsers also often store the downloaded files by default to internal memory. Go to your browser settings (Chrome, Mi Browser) and find the Downloads section. Change the save path to the folder located on the memory card.

Regularly cleaning the cache and transferring accumulated files will help keep the system in good shape. Do not allow the memory card to be filled to the end, this critically reduces the write speed and can lead to errors in the operation of applications.

Possible problems and ways to solve them

Despite the correct setup, users may experience read errors or sudden disappearance of files, often due to incorrect card extraction or file system failure, in which case formatting again helps.

If the phone doesn't see the card, try to remove it, wipe the contacts with a soft slat, and paste it back in. Make sure the card is inserted into the slot until the end, and sometimes it helps to reboot the device with the card already installed.

In rare cases, there is a conflict of file system versions. Cards larger than 64 GB are usually formatted in exFAT, whereas older models may require FAT32. Use a computer and special utilities such as SD Formatter to modify the file system.

💡

Regular backup of data from the memory card to the computer is the only way to ensure the safety of files in case of a failure of the drive.
