According to reports from Sandisk, one third of all memory cards on the market are counterfeit.
Many buyers of counterfeit products find that branded SanDisk cards are actually re-branded inferior quality cards or cards of smaller capacity.
All genuine SanDisk memory cards should have a serial number and a manufacturing country's identity. You can not determine the authenticity of a Sandisk card from an internet stock photo or simply by looking at it.
You can not determine the actual memory capacity of a counterfeit memory card by simply viewing the capacity displayed by your computer, phone or camera. Counterfeiters fraudulently overwrite the cards internal memory with a false capacity which will display a false capacity on your device. Actual memory must be checked with a test program.
To check if your Micro SD drive has the capacity and speed stated, "H2testw" is a simple tool that is distributed for free, and offers a very simple, easy-to-use interface. The program can be used by anyone who wants to know how their actual product compares to others, the real capacity and the amount of errors that can be detected on the product.
The Secure Digital "SD" standard is maintained by the SD Association (SDA). The Secure Digital format includes four card families; the original Standard-Capacity (SDSC), the High-Capacity (SDHC), the eXtended-Capacity (SDXC), and the SDIO. The cards are available in three form factors; original, mini size, and micro size.
It is not unusual to find counterfeit and generic cards with memory substantially below what is printed on the card. If you don't check your purchase, you may lose your content or damage your equipment.
