Owners of budget smartphones like the Redmi 6A often face a lack of built-in storage.The MIUI system, combined with a small amount of memory of 16 or 32 gigabytes, quickly fills with installed programs and cache, which leads to slowdown of the device and the inability to install new necessary utilities.
The Android operating system initially supports external drives, but manufacturers often limit this feature to software methods. On Xiaomi devices, the situation is complicated by aggressive optimization of the system, which prevents the standard means to move system files to an external medium.
In this article, we will discuss in detail the technical nuances of working with the Android file system, consider the Adoptable Storage method, which turns a memory card into part of the system partition, and explain how to use USB debugging. You will learn what risks exist when formatting external drives and how to properly prepare the device for modifying the storage structure.
Preparation of external storage and backup
Before you start any manipulation of system files, you need to conduct high-quality equipment. Memory cards of poor quality can cause unstable work Redmi 6A, as the speed of reading system applications is much higher than multimedia files. It is recommended to use the drives of the standard Class 10 or UHS-I from proven brands.
The process of transferring applications involves formatting the map, which will lead to the complete loss of all data on the card. If the flash card has important photos or documents, they must be copied to the computer or to the cloud storage, ignoring this step can lead to irretrievable loss of information.
⚠️ Warning: Formatting a memory card as an internal storage encrypts the data, and then the card will not be read on other devices without completely flashing and resetting.
It is also critical to ensure a stable battery charge for the smartphone. The partitioning process is energy-intensive and sensitive to power interruptions. If the phone turns off when the system tables are written, it can damage the bootloader or cyclic reboot.

Analysis of MIUI capabilities and hidden settings
The MIUI shell has its own memory management features. Unlike pure Android, the settings menu can hide some options or change their location depending on the firmware version. The standard way to check for portability support is usually in the storage settings section.
The user should go to the Settings menu → Memory: If this section does not have the option "Use as internal storage" in it after installing the memory card, then the manufacturer has blocked this function at the software level. 6A.
However, there are hidden developer menus that allow you to activate forced porting of applications, which require you to click on the build number several times in the About Phone section, and after the "You became a developer" notification appears, a new menu will open in the main system settings.
In the menu for developers, you should find the item responsible for hosting applications. Activating the option “Allow placement on an external drive” will not make the card a full part of the system, but will allow you to transfer some cache data and program resources, freeing up space in the main partition.
Adoptable Storage Method through ADB Teams
The most effective way to actually transfer applications to an SD card on Xiaomi is to use the Android Debug Bridge (ADB) toolkit, which requires connecting the smartphone to a computer and executing commands on the command line, and allows the card to be formatted as internal memory, even if there is no such button in the interface.
To get started, you need to enable USB debugging in the developer menu. Connect your phone to your PC with a good quality cable. The computer needs ADB drivers installed. Open the command line or terminal in the ADB tool folder and enter a command to check the connection: adb devices. The phone screen will see a request for debugging permission, which must be confirmed.
The next step is to identify the memory card ID, type in the adb shell sm list-disks command, and the system will give you a list of the connected drives, usually as disk:179.64 or the like, and write down this ID, which you will need for further action.
Now, the formatting command is executed. The syntax is as follows: adb shell sm partition disk:XXX private, where XXX is your disk ID. Once you execute this command, the phone can restart and the map will be formatted in a file system that only that device can understand.
adb shell sm list-disks
adb shell sm partition disk:179,64 privateOnce the instructions are successfully executed, the system will recognize the card as internal memory, a new volume will appear in the storage settings that summarizes the internal memory and cards, and applications will be installed or transferred there automatically or at the user's choice.
What to do if the team is not executed?
Manual transfer of installed applications
Once the memory card has been successfully configured as an internal storage, you can start migrating data. Not all apps support full portability, but most heavy-duty games and social media allow you to move a significant portion of your files.
Go to the Settings section → Annexes → All applications. Select the desired program from the list. If portability is possible, the "Change" or "Move to" button will be active in the application menu. SD-You click on it, you start the file copying process.
It is important to understand that the transfer speed depends on the speed class of your memory card.During the process, it is not recommended to run other heavy applications or games, so as not to put a strain on the Xiaomi memory controller.
- 📱 Open the settings of a particular application and find the item "Storage».
- 🔄 Click the “Change” button and select an external drive.
- ⏳ Wait until the process is over, the progress indicator will show the status.
Some Google Play or MIUI System services may not be portable, which is fine, as they need to stay in fast built-in storage for the operating system to work properly.
Comparison of data storage methods
It is important for users to understand the difference between normal memory card operation and internal storage mode, and the table below provides a comparison of characteristics that will help you choose the best use case for the Redmi 6A.
| Parameter | Portable storage | Internal storage (Adoptable) |
|---|---|---|
| Access from other devices | Possible right away. | Impossible without formatting |
| Portability of applications | Partial or impossible | Complete data and cache transfer |
| System speed | Depends on the card. | High (integrated into the system) |
| Security of data | Data available | Data encrypted |
Using the card as an internal storage greatly expands the capabilities of a budget smartphone, but imposes an obligation to care for the physical media. Losing or breaking such a card is equivalent to losing part of the system disk.
💡
The Internal Storage mode permanently links the card to a specific Xiaomi phone, and to use the card on another device, it will have to be formatted, which will delete all data.
Possible problems and ways to solve them
Users may experience a variety of errors during the storage modification process, and one common problem is that the interface is slow after the application is ported, indicating that the memory card is not fast enough to handle the operating system's data flow.
There may also be situations where apps stop updating through Google Play, in which case it is recommended to temporarily return the app to internal memory, update it, and then move it back to the map.
⚠️ Warning: If your phone freezes frequently after transferring apps, try to return the heaviest programs back to the internal memory. The microSD speed is always lower than that of the built-in eMMC or the internal memory. UFS storage.
In some cases, the system may misidentify the amount of space available. To correct the situation, you may need to reboot the device or re-connect the memory card through the Settings → Memory → Remove and subsequent installation.
If you plan to reset your phone to factory settings, remember that the data on the card formatted as internal memory will be lost or unreadable. Always back up important data before radical action.
💡
Use utilities like SD Maid or Files by Google to analyze which files take up the most space, which will help to clean up the storage point without having to make complex system changes.
