Notebooks are very common office supplies. When you buy them, you will generally pay attention to the key information of memory. Many manufacturers' flagship models will be equipped with top-level memory cards. So how to distinguish the true or false of a memory card is the answer many netizens want to find. Today, I'll give you the simplest way to test it, How to distinguish the authenticity of memory card? Let's see the operation of Xiaobian!
Xiaobian encountered such a problem some time ago. He bought a 32g computer memory card on a treasure online. At that time, the price was 18 yuan and included mail. Because the price of the computer memory card was too cheap, it was like giving away for free, so he bought it. Who knows, he was cheated unknowingly, Because the memory card doesn't have 32g, it's just virtual memory, so you still lose when you buy a 64g memory card. Because they are expansion cards, don't believe in too low-cost memory cards. There are traps hidden in them.
If the memory card you purchased is 32g, the actual memory is generally only 31.2g, so you can see whether it is true or false as long as you plug the purchased memory card into the computer and save 15g files. I used video to test. At that time, I uploaded 15g TV dramas, then pulled out the memory card, plugged in the computer and opened the video stored in the memory card, At this time, if the video in the memory card can be opened and played normally, congratulations. This memory card is real memory. If the video cannot be opened, I regret to tell you that it has been cheated by the merchant, as shown in the figure below:
The above method looks very simple, but many friends won't use it. They use some software to test. Some of them can't detect the true or false at all, including the 360 test. Therefore, please use the Xiaobian method, which is simple, practical, fast and can be tested without downloading any software. I hope you won't be deceived.
For the purchase of memory cards, you can choose tmall or large e-commerce websites. If you still don't trust the online memory cards, you can buy them in physical stores for on-site testing. They can be used for payment. This is the safest way.
matters needing attention:
The method is not more, but more practical. Xiaobian today is a method for everyone to thoroughly learn how to distinguish the true and false memory cards. I hope you can learn Oh.
