Difference Between TF cards and Micro SD Card

Micro SD (Secure Digital) and a TransFlash memory card are alike in many ways and can be used in place of the other. However, there are slight differences between these two storage cards.

  • Micro SD cards can support SDIO mode, in simpler terms, they can perform functions unrelated to memory, such as Bluetooth, GPS, and Near Field Communication. Whereas your TransFlash card cannot perform these functions, and purely stands for storage.

Fun Fact: SD Cards were jointly launched by Panasonic, Toshiba, and SanDisk in August of 1999. Because of their compact size, speedy data transmission, fluidity in terms of device compatibility, and other excellent characteristics, they are widely used across every portable digital imaginable.

  • There is also a switch between security segments in SD cards whereas TransFlash has no feature in it. The dimensions of a TF card is 15 mm x 11 mm x 1mm and the dimensions of a microSD card ranges around 24 mm x 32mm x 2.1 mm.

Another Fun Fact: TF cards in 2004 were accepted as the latest generation of memory cards, so that’s a fun fact byte for your amusement.

  • TF Cards can only go upto around 128GB whereas SD Cards can go upto 2 TB. Which makes SD Cards the clear winner in terms of range of storage.
  • SD Cards have more transistors than TF cards do. So more R/W can be done on an SD Card in a second as compared to that of what a TF Card can accomplish.
