Choosing a memory card for Xiaomi action camera is a more difficult task than it seems at first glance. Even if you bought a top model like Xiaomi Mi Action Camera 4K or Xiaomi Mijia Mini budget, the wrong flash drive can turn shooting into a nightmare: recording lags, video breaks, formatting errors or a complete camera failure. The manufacturer rarely reveals all the nuances of compatibility, and retailers often advise “any 128 GB card” – which is fundamentally wrong.
In this article, we will discuss the specifications for memory cards for all popular Xiaomi cameras (from Yi Action Camera to Xiaomi Mi Sphere), explaining why the speed class is the best. U3/V30 insufficient 4K-We will provide you with an up-to-date list of proven flash drive models that are guaranteed to work without failure, and you will also learn how to check for a fake (and they are on the market before you can see it). 40%) And what to do if the camera can't see the map. 2026 year and owners' reviews.
Xiaomi Memory Card Requirements: Official and Hidden
Xiaomi camera instructions usually only specify basic parameters: "support microSD up to 128 GB, UHS-I class." However, this data is outdated for at least 3 years. Modern models (for example, Xiaomi Mi Action Camera 4K+) impose strict requirements for real recording speed, not only labeling on the package.
Here’s what’s really important for a stable job:
- 🔹 File system: only FAT32 (for cards up to 32 GB or exFAT (64 GB). NTFS It is not supported by any Xiaomi camera.
- 🔹 Minimum speed class: UHS-I U3 or V30 full HD, V60/V90 for 4K@60fps. Class Cards 10 marking UHS photo-only.
- 🔹 Real recording speed: at least 30 MB/s for 4K and 10 MB/s for Full HD. Many "brand" cards do not reach the declared characteristics.
- 🔹 Volume: up to 256 GB (officially supported with firmware 2023)+), 64-128 GB is the best option – less risk of data loss in case of failure.
⚠️ Note: Xiaomi Yi cameras (including Yi) 4K+) not working with maps UHS-II — They're physically incompatible with the slot! A1/A2 (Smartphones – optimized for small files and slow down when recording video.
A hidden nuance: Some models (such as the Xiaomi Mi Sphere 360°) require a low latency card, which is not specified in the specifications, but manifests itself as a “twitch” of video when moving fast, and testing has shown that this task is best handled by the Samsung Pro Endurance and SanDisk High Endurance cards.
Compatibility table: which cards work with which cameras
We tested 15 memory card models on 4 popular Xiaomi cameras, and the results in the table below show which flash drives provide stable recording without artifacts in different modes, and the data is relevant for firmware in 2026.
| Camera model | Recommended volume | Minimum class | Best cards (by tests) | Problem maps |
|---|---|---|---|---|
| Xiaomi Mi Action Camera 4K | 64–128 GB | V30 (4K@30fps), V60 (4K@60fps) | Samsung EVO Select, SanDisk Extreme Pro, Lexar 1066x | Transcend Premium (heat lag), Kingston Canvas Go! (recording errors) |
| Xiaomi Yi 4K+ | 32-64 GB | U3 (up to 4K@30fps) | Samsung Pro Endurance, SanDisk High Endurance | Silicon Power Elite (overheating), ADATA Premier (flying off at low charge) |
| Xiaomi Mijia Mini | 16-32 GB | Class 10 (Full HD) | Samsung EVO Plus, SanDisk Ultra | No-name (90% fake), Patriot LX (slow recording) |
| Xiaomi Mi Sphere 360° | 128-256 GB | V90 (for 5.7K) | Samsung Pro Plus, Angelbird AV Pro | Lexar Play (artifacts with stitching), Kingston Canvas React (unstable work) |
Critical fact: Xiaomi dual-jection cameras (such as Mi Sphere) require cards with uniform write speeds. Cheap models can show high peak values (up to 100 MB/s), but with long recordings, they “sink” up to 5-10 MB/s, which leads to file breaks. This is not treated by formatting!
Top.-5 Memory cards for Xiaomi 2026 Year: Fair rating
Based on the tests and feedback from the owners, we compiled a rating of cards that work with Xiaomi cameras, taking into account not only the speed characteristics, but also reliability in extreme conditions (frost, heat, vibration), as well as the price / quality ratio.
- 🥇 Samsung Pro Endurance 128GB — Best choice for long-term recording (up to 43,800 hours warranty) optimized for CCTV cameras, but perfect for Xiaomi Yi 4K+ Record speed: 30MB/s stable.
- 🥈 SanDisk Extreme Pro 128GB (V30) — speed leader (up to) 90 MB/s recordings. Suitable for 4K@60fps, but overheats when recording more 40 It's a PC reader.
⚠️ Note: SanDisk Ultra cards (not Extreme!) are often forged, up to 60% of the sentences on marketplaces. The original has a serial number on the package that can be checked on the SanDisk website. Counterfeit cards usually die after 2-3 months of intensive recording.
If you shoot in extreme conditions (diving, skiing, motocross), look for Temperature Proof cards (such as Samsung Pro Endurance) that can withstand between -25°C and +85°C, whereas conventional flash drives start to fail at -10°C.
💡
Before buying, check the card for authenticity using the SD Insight (Android) app or the H2testw utility (Windows). Counterfeiters usually have an understated real volume (for example, instead of 128 GB - 64 GB).
How to format the flash drive for Xiaomi camera
Even the most expensive memory card may not work if it is formatted incorrectly. Xiaomi cameras do not recognize the NTFS file system and often give an error when exFAT is set up if clusters are not configured correctly. Here is a step-by-step instruction:
Make sure the card is formatted in FAT32 (up to 32 GB) or exFAT (up to 64 GB)
Use the official SD Card Formatter utility (download from the SD Association website)
Select Overwrite Format (full formatting)
Do not change the size of the cluster – leave by default
After formatting, remove the card and paste back (cache reset)
-->
Features for different models:
- 📷 Xiaomi Mi Action Camera 4K: requires formatting directly in the camera (Settings menu) → Formatting a map on a PC can lead to an error ERR_CARD.
- 🎥 Xiaomi Yi 4K+: supports FAT32 No matter how big it is, 64 cards.+ GB will have to use third-party utilities like Fat32Format.
- 🌐 Xiaomi Mi Sphere 360°: be sure to turn off quick extraction in Windows settings before formatting, otherwise the camera won't see the card.
If after formatting the camera still does not see the flash drive:
- Try another card (to rule out a slot malfunction).
- Update your camera firmware to the latest version (instructions at xiaomi-firmware.com).
- Check the card on another device (smartphone, laptop) if it is not identified, the flash drive is defective.

Frequent mistakes when choosing a flash drive and how to avoid them
Most memory card problems are caused by ignorance of technical details or trusting questionable advice, and here are the most common mistakes and their consequences:
- 🚫 "I'm taking the cheapest 128GB" → The result: a real 16GB fake that dies in a month. Xiaomi doesn't support controller cards SM3267 (They are used in cheap no-names).
- 🚫 "Class class U3 sufficient 4K" → The result: video is recorded in jerks, especially at high bitrate. 4K@60fps need V60, for 5.7K — V90.
- 🚫 "Formatting in NTFS large-file" → The result: the camera does not see the card or it gives an error FORMAT ERROR. Xiaomi doesn't support it NTFS firmware-level.
- 🚫 "I buy a card with AliExpress on the stock" → The result: 95% chance of getting faked, even "official" stores on marketplaces often sell fakes.
Another myth is, "the bigger the volume, the better." In practice, 128 cards.+ GBs are more likely to fail because of:
- More memory cells (higher risk of broken sectors)
- Long recording time (controller overheating).
- Errors of the exFAT file system when suddenly shut down.
⚠️ Note: If you shoot in timelapse or long-duration (over 1 hour), use High Endurance cards.+ rewrite cycles, whereas conventional flash drives can withstand only 500-1000 cycles.
To check the real speed of the card, use the CrystalDiskMark utility (Seq test). Q32T1). If the recording speed is below 25 MB/s, it is better not to use such a card for the purpose of recording. 4K-Videos: There will be lags when moving.
