Xiaomi Yi: which memory card to choose for stable camera operation

Xiaomi Yi action cameras are some of the most popular 4K video shooters, but their performance depends on a properly selected memory card. An inappropriate drive can lead to recording breaks, camera overheating or even data loss. In this article, we will examine which memory cards are compatible with Yi Action, Yi Dome, Yi 4K+ and others, and also reveal the secrets of choosing key parameters: speed, volume and reliability.

We will focus on technical details that the manufacturer does not always specify in the instructions, for example, why UHS-II cards can run slower than UHS-I, or how formatting affects the life of microSD. You will also learn which brands (SanDisk, Samsung, Kingston) perform best in tests with Xiaomi Yi, and which are often forged.

What memory cards support Xiaomi Yi cameras: official requirements

Xiaomi’s Yi series camera documentation specifies minimum memory card requirements, but they often prove insufficient for stable operation. Class 10 or UHS-I (U1/U3) microSD cards are officially supported with up to 256 GB. However, in practice, even among certified cards, there are models that cause 4K recording freezes or file system errors.

Key parameters that should be paid attention to:

• 🔹 Speed class: Minimum Class 10 (10 MB/s), but for 4K required U3 (30 MB/s) or V30 (30 MB/s guaranteed recording speed).
• 🔹 Form factor: microSD only (not miniSD or microSD) SD). Adapters do not affect compatibility.
• 🔹 File system: Xiaomi Yi cameras work with FAT32 (up to 32 GB and exFAT (from 64 GB). New models (2022)+ may not recognize maps formatted in NTFS.
• 🔹 Brand: SanDisk Extreme, Samsung are recommended EVO Plus, Kingston Canvas Go! Plus. no-name cards or fakes often cause crashes.

Important: Yi 4K+ and Yi Action 2 cameras require cards with high random write speeds because they use data buffering. For example, the SanDisk Extreme Pro performs better than the budget Kingston A1, despite similar specs on paper.

⚠️ Attention: Marked cards A1 or A2 (Application-optimized ones are not always suitable for video recording, they can provide high read speeds, but low sequential write speeds, which is critical for video recording. 4K.

Top.-5 Memory cards for Xiaomi Yi: rating on reliability and speed

Based on user tests and laboratory checks, we compiled a rating of maps that show stable work with Xiaomi Yi cameras. We took into account not only the declared characteristics, but also the real speed of recording during long-term shooting in 4K, as well as resistance to temperature changes.

Note: SanDisk Ultra cards (not Extreme!) often cause errors when writing 4K on Xiaomi Yi 4K+, despite the U1 class.This is due to the low minimum write speed (less than 10MB/s), which is not enough for high bitrates.

Why the memory card does not work in Xiaomi Yi: common mistakes

If the camera doesn't recognize the card or if it gives an SD Card Error, the problem may lie not only in the drive itself, but also in the device settings.

• 🛑 The map is not defined: check that it is formatted in FAT32 (Up to 32GB) or exFAT (from 64GB).Xiaomi Yi cameras don't support NTFS.
• 🔄 Freezes when recording: most likely, the card speed is not enough for the selected resolution. Try to lower the bitrate in the camera settings (Settings). → Video Quality).
• 🔥 Camera overheating: Cheap cards without heat-resistant controllers can overheat, leading to emergency shutdowns.Use models labeled High Endurance.
• 📛 File system error: If the card was previously used on another device, format it inside the camera (Settings) → Format SD Card).

For example, there are often fake SanDisk Extremes on the market with real write speeds below 10 MB/s. You can verify authenticity using the H2testw (Windows) or F3 (macOS/Linux) utility, which tests real volume and speed.

⚠️ Note: If files are still not saved after formatting the card in the camera, try updating the Xiaomi Yi firmware. In older versions of the software (until 2021), there was an error that caused the device to work incorrectly with cards with a volume of more than 128 GB. Original SanDisk cards have: - Logo with clear edges (it is blurred on fakes). - Serial number on the back, which can be checked on the manufacturer's website. - Package with a hologram and anti-opening protection. Counterfeit products are often sold without a branded adapter or with typos in the model name. How to format a memory card for Xiaomi Yi Memory Card correctly. Xiaomi Yi cameras require specific file system settings that depend on the storage capacity: Up to 32 GB: use FAT32 (64GB: exFAT only (cameras do not support) NTFS). Formatting: Better to perform inside the camera via the Settings menu → Format SD Card. This ensures that clusters are compatible. If you format a map on a computer, select: 🖥️ Windows: Use the utility SD Card Formatter (official software from the SD Association with Full (OverWrite) Format settings. 🍎 macOS: in Disk utility, select the scheme GUID Important: after formatting on a PC, make sure to format directly in the camera, which will create the right folder structure for recording videos and photos. Formatting in the camera (Settings) → Format SD Card) Check the speed with the help of H2testw Update Xiaomi Yi firmware to the latest version Make sure the class card is U3/V30 for 4K--> Recording speed and bitrate: how they affect video quality Xiaomi Yi cameras use different bitrates depending on resolution and frame rate. If the memory card speed is lower than required, the video will break and the sound will be distorted. The table below shows the minimum recording speed requirements for different modes: Bitrate Shooting Mode (Mbps) Minimum Card Speed (MB/s) Recommended Class 1080p@30fps 15–25 10 Class 10 1080p@60fps 30–40 20 U3/V30 4K@30fps 60–100 30 U3/V30 4K@60fps 100–130 60 U3/V60 For example, for a film in 4K@60fps Xiaomi Yi 4K+ You will need a card at least a speed of recording. 60 MB/s. If you use Samsung EVO Plus (80 MB/s, the camera will work smoothly, but with the Kingston Canvas Select (45 MB/s) video will be interrupted every time 5–10 Advice: if you shoot in format H.265 (HEVC), The bitrate is lower, but the card must maintain a high rate of random write, otherwise files can be corrupted. 💡Before buying a card, check it on the camera manufacturer's website. Xiaomi periodically updates the list of compatible models for new firmware. How to prolong the life of a memory card in Xiaomi Yi Memory cards in action cameras wear out faster due to constant overwriting of data.
