INTRODUCE
In today's digital society, digital devices have become an important part of human life. The SD card and TF card have become the storage 'soul' of these digital devices. As mobile storage devices, their advantages are obvious: small and light, large capacity, fast transmission speed, high data reliability and so on. Next, the editor will introduce the SD card and TF card in detail from the following elements.
The full name of SD card is Secure Digital Memory Card, which is a very common memory card device. SD cards were originally jointly launched by the SD Association in 1999 to solve the storage problems of digital cameras. Since then, SD cards have been widely used in the storage and transmission of digital devices such as mobile phones, tablet computers, digital cameras, and music players. At present, SD cards have been developed to the fifth generation, the fastest of which is the UHS-II standard card, and the maximum capacity can reach 2TB.
TF card is T-Flash card, also known as micro SD card, that is, micro SD card. SD card is larger than TF card. Applied to different products, SD cards are generally used in larger electronic equipment: such as computers, cameras, AV and other equipment, while TF cards are generally used in mobile phones. TF card can be converted into SD card by inserting the adapter (adapter), but generally SD card cannot be converted into TF card. There is a (lock) switch on the SD card, which is the write protection switch, but there is no TF card.
When using the SD card, ensure that it is in good contact, do not pull out and insert it frequently, and do not place it in a high temperature or humid environment. Do not store too much data in the SD card during use, otherwise it will reduce the operating speed of the SD card. Most importantly, in order to protect the data security in the SD card, the SD card must be cleaned and backed up regularly.
When using a TF card, try to avoid plugging and unplugging the flash memory card. When the digital device is about to run out of power, or when the power is alarming, it is best not to use the flash memory card to read and write data. Try to leave as much space as possible. When continuous shooting is not supported (1 means that the camera does not support it, and 2 means that the speed of the TF card cannot keep up), it is best not to do continuous shooting. The TF card should be handled with care as much as possible, and it should not be dropped, bumped, pinched, etc., which may cause damage; avoid places where it is exposed to high temperature, high humidity, strong magnetic field, and strong electric field.
SD card and TF card should be our two common memory cards, they seem to be very similar, but there are some differences. Let's briefly introduce the difference between them.
Shape and Size
SD card and TF card are very different in shape. SD card is larger than TF card, the size is 32×24×2.1mm, while the size of TF card is 15×11×1mm. That is to say, the size of TF card is only 1/3 of SD card. In this way, TF cards are more suitable for some small devices, such as mobile phones, digital cameras and so on.
Scope of Application
Due to the relatively large size of the SD card, it is applicable to a wider range of devices than the TF card. Our common cameras, computers, TVs, stereos, etc. can all use SD cards for storage. The TF card is mainly suitable for small devices, such as mobile phones, tablet computers and so on.
Interface specification
Since the TF card was released, it has been using the Micro SD card format. The SD card is divided into standard SD card, Mini SD card and Micro SD card three formats. This also affects their scope of use.
RAMS multi-capacity A1 performance TF card can quickly load and run APP to store more high-quality photos and files without worrying about capacity; the reading speed is as high as 120MB/s, and it can transfer files quickly, and can transfer 1000 photos within one minute ; Adapt to mainstream Android smart digital devices, widely compatible with mobile phones, tablets, drones, driving recorders, TVs, etc. on the market.
