- 💰 Samsung EVO Plus: Optimal price/quality ratio. 128GB U3 Often cheaper than analogues by 10-15%.
- ⚡ Kingston Canvas Go!: Budget option with good speed (up to 100 MB/s). POCO M6 Pro.
Avoid High Endurance Transcend cards, which are designed for DVRs and are 20 to 30 percent more expensive at the same speed, and don't take Silicon Power without checking, because they have a high percentage of defects in the lot.

Compatibility of memory cards with Xiaomi Redmi models
Not all memory cards work with all Redmi models, but here are the key limitations:
| Model Redmi | Max. Volume. | ExFAT support | Adoptable Storage |
|---|---|---|---|
| Redmi A2 / A2+ | 512GB | Yes. | No. |
| Redmi Note 12 / 12 Pro | 1TB | Yes. | Yes (MIUI 13+) |
| POCO X5 / X5 Pro | 1TB | Yes. | Yes. |
| Redmi 10C / 9A | 256GB | No (FAT32 only) | No. |
On older models (Redmi 4X, 5A), 64GB+ cards may not be defined due to firmware limitations, and the solution is to upgrade MIUI to the latest version or use cards to 32GB.
If your Redmi can’t see the memory card:
- Reboot the phone.
- Format the card in FAT32 via your computer.
- Check the card slot for dust or damage.
- Update the firmware in Settings → About the phone → System update.

Frequent mistakes when choosing a memory card for Redmi
Many people buy cards without considering the specifics of their smartphones, and here are some of the most common mistakes:
- 💸 Overpayment for volume: Purchase 512GB for Redmi 9C, It doesn't support adoptable storage. Files will still take up internal memory.
- 🐢 Savings on speed: Class 10 card U1 slow down 4K-Video from Redmi Note 13 Pro+. You need a minimum. U3.
- 🔄 Ignoring the format: ExFAT cards don't work on Redmi 6A and older without manual formatting.
- 🛒 Buying without verification: 40% of cards on Avito and 15% on Wildberries are fakes (data from the study of Roskoshestvo for 2023).
Another mistake is using the card as an internal storage on weak smartphones (for example, Redmi 8A), which slows down the system, since the read/write speed of the microSD is 2-3 times lower than that of the internal memory eMMC 5.1.
