Manufacturers write mysterious letters and numbers on packages: A1, U3, V30. What do they mean and should they overpay for quick cards?
Speed classes determine how fast a card will write and read data, and Xiaomi is critical to consider:
- 📱 A1/A2 — optimized for applications. A2 It runs games and programs faster (important for Black Shark or Black Shark). POCO F-series).
- 📷 U1/U3 — videography. U3 needle 4K@60fps (For example, on Xiaomi. 13 Ultra).
- 🎮 V30/V60/V90 —"gaming classes for high bitrate recordings (relevant for streamers).
🔹 Recommendations for Xiaomi models:
- 📱 For Redmi. 10A/12C (budgetary A1/U1 — overpaying doesn't make sense.
- 🎯 For POCO X5 Pro or Redmi Note 12 Pro take it. A2/U3 — This is the best balance between price and quality.
- 🎮 For Black Shark. 5/6 or videotaping 4K need V60/V90.

If your Xiaomi supports UFS 3.1 (for example, Xiaomi 14), then the microSD will not give you a boost in speed – it is better to buy a smartphone with a large built-in storage.
What memory cards Xiaomi officially supports: file format and file system
Not all memory cards are compatible with MIUI firmware.
- Format: Most Xiaomi runs microSD (up to 32 GB) and microSDXC (64 GB to 2 TB). microSDHC cards (32-64 GB) are not supported by all models (e.g. Redmi 9A will not see them).
- File system: 📁 FAT32 — It works everywhere, but is limited to files up to 4GB. 📁 exFAT – supported by MIUI 10 and newer (for cards) >64GB). 📁 NTFS — Not recommended (may not be installed).
🔹 How to Check Compatibility?
- Go to Settings → Memory → Memory Map.
- If the system offers to format as internal memory, the card is compatible.
- If it says “not supported” check the format (maybe you need to reformat it to exFAT).
- Data portability: Go to Settings → Memory → Memory Map → Move data. Select files (photos, videos, music) and wait until it is completed.
⚠️ Note: If Xiaomi says "Map is damaged" after inserting the card, don't format it directly via your phone! SD Formatter (official program from the SD Association).

Formatting a card as “internal memory” speeds up applications but shortens the life of the card (due to frequent overwriting), and using portable storage mode is better for durability.
