When it comes to storage products, SanDisk is no stranger to both consumers and professional enthusiasts. As the world's largest memory card supplier, SanDisk is recognized as a leading brand in the storage industry. In 2016, SanDisk was acquired by Western Digital and now operates independently as its subsidiary.
 
As a flash memory, excellent flash memory particles are a necessary guarantee for the performance of the memory card. The manufacturing of flash memory particles requires strong capital strength and technology accumulation. SanDisk and Toshiba have joined forces to build a joint venture to produce flash memory chips. SanDisk has the world's second-largest market share of flash memory chips, second only to Samsung. Relying on its strong technical strength, SanDisk memory cards use its own flash memory, and the quality of the products is stable and reliable.
 
Although SanDisk's share of the flash memory chip market is slightly weaker than Samsung's, SanDisk has always been an industry leader in memory card products. SanDisk was involved in the initial development of a variety of memory cards, including SD cards, Micro SD cards, and CF cards, and is a member of the Board of Directors of the SD Card Association. In 2016, SanDisk released the 1TB SanDisk Extreme PRO SDXC, the world's largest SD memory card.
 
The SanDisk memory card product line is divided into three major series: Extreme Pro, Extreme, and Ultra, and each series is also divided into different small series according to different read and write speeds. The SanDisk Extreme Pro and Extreme series are backed by a lifetime warranty, and the Ultra series is backed by a 7-10 year after-sales warranty for reliable after-sales service.
 
In the memory card market, SD card occupies the mainstream position, SD card is also divided into standard SD card and Micro SD card, SanDisk standard SD card flagship product Extreme Pro UHS-II SD card supports the new UHS-II transmission standard, the official nominal maximum read speed can reach 300MB/s, ultra-high read and write speed can fully meet the needs of professional photography. UHS-II memory cards are priced at a higher price, with the 64GB version priced at 899 yuan.
 
However, it's important to note that UHS-II standard memory cards, while fast, are only capable of their full performance on a small number of professional devices. At present, most devices only support UHS-I standard memory cards at most, and UHS-I memory cards are much cheaper. Before purchasing a memory card, you need to know the transfer standards supported by the product to avoid unnecessary costs. The 64GB version of the SanDisk Extreme Pro series UHS-I memory card is only 239 yuan, and the maximum read speed of 95MB/s is also at the upper level of similar products.
 
SanDisk products also include the Extreme and Ultra series of memory cards that also support the UHS-I standard. In the Extreme series, the maximum write speed is 60MB/s for products with a capacity of less than 64GB, and the maximum write speed is 90MB/s for products with a capacity of more than 128GB. The Ultra series has weak performance, with a read speed of 80MB/s, but its price is relatively low, and the 64GB version costs 159 yuan, which is suitable for users who do not have high performance requirements.
 
Mobile phone expansion is one of the main uses of Micro SD card, and the SD Association has also introduced the minimum speed standard A1 for mobile phone expansion, so that the APP installed on the memory card can also run smoothly. SanDisk Micro SD cards support the A1 standard and can be purchased at will.
 
SanDisk Micro SD cards are also divided into three series: Extreme Pro, Extreme, and Ultra, the Extreme Pro series supports the UHS-II standard, which is the flagship product in the SD card, but there are not many devices that support the UHS-II standard, and users need to distinguish them when purchasing to avoid wasting performance. The Extreme series supports the V30 standard and can record HD video.
 
As the oldest memory card in the world, the SanDisk Extreme Pro CF card supports the VPG65 standard, which means that the minimum write speed for video recording is 65MB/s, so you can record 4K video without stress. However, its price is more expensive, and the 64GB version costs 679 yuan. If users do not have ultra-high performance requirements, the Extreme series CF card is also good enough for daily shooting, and the price is affordable, the 64GB version is only 399 yuan.
