Compared with brands such as SanDisk and Kingston, Lexar is not well known to consumers in China. However, Lexar has a good reputation among professionals and photography enthusiasts, and some enthusiasts have likened SanDisk and Lexar to "the Nikon and Canon of memory cards". Lexar was once a brand of Micron and was acquired by China's Longsys Electronics in 2017 and became a wholly-owned subsidiary of Longsys.
 
Since memory cards are used as storage media in all types of devices, memory cards need to be compatible well across devices. Lexar's quality laboratory has thousands of digital devices, and it is not only necessary to test the basic shock-proof and anti-interference performance of the memory card before leaving the factory, but also to test the compatibility of the memory card on the device to ensure the superior compatibility of the Lexar memory card.
 
Lexar memory cards will see words similar to "633X" on the product name and card surface, in fact, this is the most traditional memory card speed identification, called "X notation". The number in front of X is the calculated rate multiple, and the maximum read speed of the memory card is indicated based on the CD-ROM transfer rate of 150kB/s as the 1x speed. For a card marked "633X", the maximum read speed is 95MB/s (633×150KB/s).
 
Since Lexar's memory card products are named after "X notation", many Lexar SD cards and Micro SD cards use the same product name, which is easy to cause confusion. Users need to be aware of the type of card when purchasing.
 
Lexar's flagship standard SD card product, the 2000X, supports the UHS-II transmission standard, with a maximum read speed of 300MB/s and a write speed of 260MB/s, which is the top standard for standard SD cards. As a memory card used as an imaging device, the Lexar 2000X also meets the highest standard for video recording, V90, which means that the minimum write speed for video recording is 90MB/s. The price of the superior Lexar 2000X is also relatively high, with a price of 999 yuan for the 64GB version.
 
Compared to the flagship product, the 150MB/s UHS-II SD card 1000X can also meet most professional needs. The version above 64GB supports the V60 standard, which can record 4K videos smoothly. In comparison, the UHS-I enabled Lexar 633X memory card has a maximum read speed of 95MB/s, which is more than enough for everyday shooting needs. The 64GB version 1000X is priced at 299 yuan, and the 633X is priced at 179 yuan.
 
Micro SD card 1000X supports UHS-II and V60 standards, suitable for drones and GoPro and other products, 64GB version is priced at 329 yuan. The 633X is suitable as a mobile phone expansion card, with a maximum read speed of 95MB/s, supports V30 and A1 standards, and can run programs or shoot videos. The 64GB version is 149 yuan, which is cheaper than SanDisk Extreme and cost-effective.
 
With the development of storage technology, the performance of CF card is gradually lagging behind, in addition to being replaced by SD card, CFast has replaced CF as the new flagship memory card. Although the names of the two are similar, CFast memory cards are not compatible with CF cards, so you need to be aware when purchasing. The Lexar CFast memory card 3500X adopts the CFast 2.0 standard, with a maximum read speed of up to 525MB/s and supports the VPG130 video standard, which fully meets the photography needs of professional-grade devices such as the Canon EOS-1D X Mark II. The price of the 3500X is high, and the 64GB version costs 1299 yuan.
