In recent years, Transcend has not had much success in the storage market, but its solid product strength has still earned it a good reputation. Transcend currently has subsidiaries in 14 countries and regions around the world, and its product line covers a wide range of fields such as memory, portable hard drives, and memory cards.
 
Macbooks have a small capacity, and many users have strong expansion needs, and Transcend has launched Apple's dedicated expansion card for Macbook users. Essentially, Transcend's "dedicated expansion card" is also an SD card, but in order to accommodate the shallower slot of the Macbook, Transcend's expansion card adopts a "hidden design" that shortens the length of the memory card and makes it invisible when inserted into the Macbook. The 64GB version is priced at 279 yuan, and it is recommended for users with corresponding needs to buy.
 
Transcend's professional SD card UHS-II U3 has a maximum read speed of 285MB/s, but the write performance of 180MB/s is not very good among professional products, and there is only a 32GB version to choose from, fortunately, the price of 279 yuan is not expensive, if you need a UHS-II standard memory card, you can consider buying this product.
 
Transcend's mainstream SD cards and Micro SD cards are more expensive than professional SD cards at a reasonable price. Transcend's Micro SD card U3M has a maximum read speed of 95MB/s and supports the V30 transmission standard, but the 64GB version is priced at 359 yuan, which is 50% more expensive than the better SanDisk Extreme PRO UHS-I.
