Fake memory cards are a market scourge: according to Rospotrebnadzora, up to 20% of microSD in the Russian market is fake. Here are 5 signs of forgery:
- Price below market price: Original SanDisk Ultra 128GB can't cost 600 ₽ — The minimum cost of memory chips makes this impossible.
- No brand logo on the package. Official cards are sold in sealed hologram blisters.
- Check the speeds with CrystalDiskMark or SD Insight (Android).
