Our mission
Our mission is to help you to find the real speed of the card, even if it is built-in storage or external card. Based on the speed, our app will classify your card.
As you probably know, there are a lot of fake SD card on the market, and even if it is a genuine card, the speed is highlighted as “up to”. That can mean anything.
With our SD Card Test app, you can measure the real speed, including reading and writing speeds. You can test your card with different combinations.
What’s more important, using the data verification technology (available in Pro), you can confirm that your card is not damaged, and it is not fake (not labeled higher than it is in fact).
