This post explains what a TF Card is, how it differs from a microSD card, and which one has better storage. TF cards and microSD cards are among the most popular and widely used memory card formats. While they are essentially the same and can be used interchangeably, there are slight differences between the two.
What is a TF Card and is it better storage than a microSD card?
TF Card, also known as a TransFlash card, is an older type of memory card used to store and transfer data between electronic devices. All microSD cards today are essentially descendants of the original TF card, with added improvements.
What is a TF Card?
In the early 2000s, SD cards were primarily used to provide additional storage to devices with limited internal memory. However, since they were bulky and had lower writing speeds, people felt the need for a more compact and faster memory card. As a result, SanDisk and Motorola introduced TF cards in 2004.
Soon after their launch, TF cards became the world’s smallest memory cards for use in mobile devices, such as phones, cameras, and other portable gadgets. They had the same functionality and capabilities as SD cards, except for their smaller size. However, they existed as a standalone product with limited recognition. Later in 2005, TF cards were adopted by the SD Association (the organization responsible for setting standards for SD card formats) and rebranded as ‘microSD‘.
Difference between a TF card and a microSD card
A TF card and a microSD card are physically identical and interchangeable for storage purposes. However, the evolution of the microSD standard introduced the SDIO feature, which the original TF card lacked.
The Secure Digital Input/Output (SDIO) feature is an extension of the SD card standard that allows SD cards to do more than just store data. Unlike regular SD or microSD cards, SDIO cards incorporate additional hardware components to perform non-memory tasks, such as acting as a Bluetooth adapter or GPS receiver.
SDIO cards were more popular in the early days of portable devices when built-in Wi-Fi, GPS, and other features were not standard. Today, their usage has declined, but they remain a notable example of how expandable memory cards evolved to perform diverse functions.
TF Card vs microSD: which has better storage?
When launched initially, TF cards had lower storage capacities starting at 32MB. So if you compare modern microSD cards to the original TF cards, microSD cards offer significantly larger storage capacities, ranging from 32GB to over 1TB (with faster read/write speeds). However, the comparison is meaningless since microSD is the current, improved iteration of the TF card standard.

Which is better SD card or TF card?
The comparison between an SD card and a TF card depends on the use case. A TF card is physically smaller than an SD card, but both support the same standard and offer different capacities (ranging from 2GB to 256GB, and even higher). TF cards can be used in SD card slots (via an adapter), but SD cards cannot fit into microSD slots. TF cards are better for smaller devices with limited space, and SD cards are better for devices designed specifically for them (like DSLRs or camcorders).
Can you put a TF card in a microSD slot?
Yes, you can put a TF card in a microSD card slot since they are physically identical in size and shape (15mm x 11mm x 0.7mm). When TF cards were rebranded as microSD, they became interchangeable and compatible with the same slots and devices.
