(1) The Fully Automated Manufacturing Process of SD Cards
SD cards (Secure Digital Memory Cards) are storage cards based on semiconductor flash memory technology, conceptually led by Japan’s Panasonic in 1999, with Toshiba and the American company SanDisk participating in substantial research and development. In 2000, these companies initiated the establishment of the SD Association (SDA), which attracted a large number of manufacturers to participate, including IBM, Microsoft, Motorola, NEC, Samsung, and others. With the promotion of these leading manufacturers, SD cards have become one of the most widely used storage cards in consumer digital devices. SD cards are multifunctional storage cards with features such as large capacity, high performance, and security.
(2) Characteristics of Several Major SD Card Brands:
Currently, there are many SD card brands on the market, and well-known brands each have their own characteristics.
SANDISK
The SANDISK brand SD card is probably the most common on the market, with such “blue cards” available in almost every digital specialty store. In fact, SANDISK’s SD cards are not all low-speed; there are also high-speed models (black cards).
Kingmax
As a manufacturer of branded memory, KINGMAX has been dedicated to the development of storage cards in recent years. They use a unique integrated packaging technology (PIP), making it difficult for counterfeiters to replicate. The Kingmax SD card has a maximum transfer rate of 10MB/s, featuring waterproof, shockproof, and pressure-resistant designs, meeting various requirements for outdoor photography.
PANASONIC
As the creator of the SD standard, Panasonic’s technology is among the best SD cards on the market. However, most Panasonic SD cards available on the market do not come with a warranty, so it is essential to inquire about the warranty period when purchasing.
Kingston
Kingston, as the world’s largest memory manufacturer, produces SD cards that eliminate interface circuits, making them the smallest among many flash products (only the size of a postage stamp, weighing less than two grams). This is also the reason why many digital cameras, MP3 players, and handheld computers choose SD cards as their storage medium. However, due to the size of the product, it is relatively difficult to increase the capacity of SD cards. Additionally, all Kingston SD card products offer a warranty of up to 5 years.
