  1. Introduction to memory card
  SD card memory card is an independent storage medium used in mobile phones, digital cameras, portable computers, MP3 and other digital products. It is generally in the form of a card, so it is collectively called "memory card", also known as "digital memory card". "Digital memory card", "storage card", etc. Memory cards have the advantages of small size, easy portability and simple use. At the same time, since most memory cards have good compatibility, it is easy to exchange data between different digital products.

  4. Memory card purchase
  ① When purchasing, you should "live within your means" and choose to buy according to the capacity that you can frequently use. Don't think "bigger is better", or even blindly pursue "bigger is better" for the sake of "prominence". Not only will you spend more money, but the extra part will also end when the life of the card expires, and the access speed is still there. It will be much slower than a suitable size card.
  ② Don’t blindly pursue high-speed cards. Because the shooting speed of a digital camera is determined by multiple links, from image input, A-D conversion, CPU processing, to cache size and speed, they all play a decisive role.
  ③ Buying parallel imports does not necessarily mean you get an advantage. It has been mentioned above and will not be repeated. I just want to emphasize one point: the production process is rough, the surface is pitted and uneven, and the trademark printed with rough fonts is like a water-soaked card. It is not a parallel import, but a fake.
  ④ The FAT32 format for memory cards is more advanced than the FAT16 format. The new digital cameras currently launched already support the FAT32 system. Therefore, when purchasing a memory card for mobile storage, handheld computers, mobile audio and video equipment, you must choose FAT32 system card; when used on digital cameras, you have to distinguish the era when the camera was launched to decide whether to buy a FAT16 system card or a FAT32 system card.
