How to distinguish the original from the fake
The electronics market is oversaturated with counterfeit products, and memory cards are no exception: counterfeit drives often have a modified controller that shows the computer or phone the full volume (for example, 64 GB), but physically holds only 4-8 GB.
When this fake volume is overflowing, old data is overwritten with new ones, which leads to irreversible damage to files, and visually distinguishing a quality fake from the original becomes increasingly difficult, as the packaging and printing are highly accurate.
- 🔍 Check the hologram and the quality of the printing: on the original maps of Samsung and Sandisk logos are clear, without blurring.
- 💾 Use testing tools: programs like H2testw or F3 PCs can record test data for the entire volume and reveal the real size.

The place of purchase is worth paying special attention: large electronics chain stores value their reputation and rarely sell an open marriage, while the risk of running into counterfeits increases many times in market collapses.
