## Key points

- Fake cards may falsely claim to hold more data than they can.
- Check prices, sellers, brands and packaging before buying.
- Test capacity and speed before saving important files.

## Summary

Counterfeit SD cards can put buyers’ files at risk by claiming to hold more data than they really can, leading to files being lost, corrupted or overwritten. With memory shortages pushing up prices, suspiciously cheap cards may be tempting, but checking a card before storing important files can help avoid problems.

Warning signs include unusually low prices, unauthorised third-party sellers, unfamiliar or imitated brands, and packaging with missing labels or warranty details. Windows users can test capacity and speed with H2testw; the open-source F3 tool checks whether written data can be read back, while CrystalDiskMark can compare performance with the card’s stated speed.
