How to increase memory on Xiaomi Smart TV: from flash drive to cloud storage

Xiaomi Smart TV owners sooner or later face a shortage of internal memory — especially if they actively install apps, download movies or use the TV as a media center. Even models with 32 GB on board quickly clog up: the system takes up to 8-10 GB, the cache of applications grows by leaps and firmware updates require free space, as a result, users see the words “Memory is full” or encounter interface brakes.

There are a number of ways to solve this problem, from connecting an external drive to optimizing existing storage, but not all methods are equally effective, such as cheap storage. USB-And these low-speed flash drives can not just slow down, but they can completely block the TV from recording data. 6 Proven methods that actually work on the Mi TV 4A/4S/4X/5/5X Other models, and what errors lead to data loss or system failures.

1. Connecting an external storage device: USB-flash-drive SSD

The most obvious way to expand memory is to use external memory. USB-But there's a nuance here: not every flash drive works, and the wrong file system format can lead to errors. Xiaomi TVs support two options for working with external drives:

Option 1: Normal connection (for media files).

A flash drive or hard drive is used as an additional storage for movies, music and photos, in which case it is enough to format the drive into a digital format. FAT32 or exFAT (the latter is preferred for files larger than 4 GB). read/write speed is not critical, but for Full HD-Content is better chosen USB 3.0.

Option 2: Adoptable Storage (Adoptable Storage)

This feature allows you to use the flash drive as part of the main storage, which allows you to transfer applications and data to it. However, Xiaomi does not officially support such a mode on all models, and improper actions can lead to a system failure.

⚠️ Attention:

If you plug in a flash drive as internal memory, the TV will format it into ext4 or f2fs, after which the drive will not read on a PC without additional software.

2. How to choose the right flash drive for Xiaomi TV

Not all. USB-And the drives are equally useful. Cheap flash drives with low write speeds (< 10 MB/s) will slow down when you write cache or updates, and some models will not be determined by the system at all:

• 🔹 Interface: USB 3.0/3.1 (Blue connector - mandatory for Mi models TV 5 And newer. On old TVs (4A/4S) enough USB 2.0, but the speed will be limited. 30-40 MB/s.
• 🔹 Size: Minimum 32GB for media files, 64GB or more if you plan to port applications. Drives over 256GB may not be determined on budget models.
• 🔹 Record speed: Not less than 20 MB/s (class) UHS-I U1 For or above. 4K-content U3 (30+ MB/s).
• 🔹 Form factor: Compact flash drives (e.g. SanDisk Ultra Fit) do not block neighboring ports.
