Bought a cheap SD card? It might be fake.
Fake SD cards report more storage than they actually have — and they silently corrupt your photos, videos and files. SD Card Test Pro detects fake cards, measures real read/write speed, and tells you exactly what type of storage you have. No ads. No limits.
✔ Fake card detection — verify your card is genuine
✔ Read & write speed test — see the real performance
✔ Damaged card detection — catch problems before data loss
✔ Internal storage test — benchmark your phone's built-in memory
✔ Storage type detection — eMMC, UFS 2.0, UFS 2.1, UFS 3.x
✔ SD card class detection — Class 10, UHS-I, UHS-II, UHS-III
✔ Supports Micro SD, SDHC, SDXC
✔ File system support — FAT32, exFAT, ext4
✔ Customized benchmarks for advanced users
✔ One-tap result sharing
Works great for:
→ Checking cards bought online (Amazon, AliExpress, Temu)
→ Testing SD cards for cameras, dashcams, drones
→ Verifying storage before storing important data
→ Diagnosing slow phones or apps
Easy to use — results in minutes, even for beginners.
Pro version advantages:
★ No ads
★ Faster updates and bug fixes
★ Customized benchmark settings
Supported cards: Micro SD, SDHC, SDXC, built-in eMMC/UFS storage
Technical note: For accurate class detection the app needs at least 4 GB written and 10 seconds of test time. For FAT32 cards, use multiple smaller files instead of one large file.
