What is TF card and difference between an SD card and a TF card?


What is the TF card and what is the difference between an SD card and a TF card?:-

You may be familiar with Micro SD cards, but have you heard about TF cards? This article describes what a TF card is and how it differs from an SD card. The most widely used TF memory cards and MicroSD cards for storing data in digital format can be used on many devices, such as computers, laptops, PDAs, game consoles, MP3 players, tablets cameras, and more. Additional storage for the device is offered in a variety of storage sizes from a few megabytes to several gigabytes.

Today, smartphones are used not only for communication but also for storing numerous items such as photos, videos, and important documents. Memory cards play an important role in this function.


When talking about memory cards, you can immediately think of TF cards and Micro SD cards, but you can get confused about these two cards. You do not know if they are the same or different.

Many devices offer the option of using external media, but not all offer the same compatibility, so there are several types of memory cards or flash drives. In this case, some devices work with a MicroSD memory card, while others require a TF memory unit to store data. Let’s briefly explain what these memory cards are and what makes them different. You can find memory cards of type TransFlash, TF, T-Flash, MicroSDHC, and MicroSD.

What is TF Memory Card:

The TF memory card was first released in 2004 by SanDisk Corporation. Introduced as the world’s first smallest memory drive, this memory card was launched in nail size. TF memory cards are no different from MicroSD cards. Also, there are no technical or physical differences in the specifications, but there are some differences between them.

The special thing about SD cards is that they are available in different sizes and form factors. There are three different sizes: standard, mini, and MicroSD. The standard size is the largest size with dimensions 32.0 x 24.0 x 1.4 mm and 32.0 x 24.0 x 2.1 mm. These are the sizes that are most commonly compatible with devices such as laptops. Widely used in devices such as iPods, PDAs, digital cameras and smartphones. The TF card and the SD card generally refer to the TF card and the micro SD card. In fact, there is no physical or technical difference between the TF card and the Micro SD card.

What is SD Memory Card:-

An SD card (i.e., Secure Digital Card), which was born before the TF card, was launched in August 1999 by Panasonic, Toshiba, and SanDisk. This is a new generation memory device based on semiconductor flash memory.

When we talk about choosing an SD card, many of us tend to include microSD cards in this category. A microSD card is similar to the TF card and does not mix the two concepts again since the SD card is first distinguished by the title “micro”.

Recognizing that SD cards are ultra-small, portable, and lightweight, they are larger than TF cards and, in general, are used in digital cameras, personal digital assistants (PDAs), media players, and sometimes desktops and laptops. It adapts to large digital devices. There is an SD card slot!

What is the MicroSD Card:-

It was introduced as the world’s smallest external storage device. After its success in the mobile phone market, TransFlash cards have been officially adopted by the existing Digital Storage Organization SD Card Association.


Micro SD card refers only to secure digital cards. This is a type of mobile device and mainly applies to mobile phones. This small mobile storage device was originally developed by SanDisk on behalf of TransFlash.

TransFlash cards were considered part of the third category of digital storage devices in the official Secure Digital database. The other two gadgets are mini-SD and SD memory cards.

In the process, SanDisk changed the name of the device to a Micro SD card and started producing a product that would be used as the standard memory storage chip currently used in most mobile phones.

The new micro storage device is designed based on the original TransFlash card, but there are some differences between the two chips. On the other hand, memory cards have some similarities.

What is the difference between an SD card and a TF card?

1.Different Names

In fact, both types have their own identities.

    • TF card is a flash memory card and has other well-known names such as T-Flash, TransFlash, microSD, etc.
    • SD is an acronym for Secure Digital, a proprietary non-volatile memory card format. Due to many capacity standards so far, derivative products such as SDHC, SDXC, SDUC have been developed.

2. Different Origins

TF cards were first introduced to the market in 2004 but were not members of SD products at the time. The SD Association obtained it from Motorola and SanDisk the same year. Other memory cards adopted by the SD Association include miniSD and SD cards.

Currently belonging to the same SD product of the SD Association, the SD card was first implemented by Panasonic, Toshiba, and SanDisk in August 1999.

3. Different size and Appearance

On the one hand, differences can be found by dimension.

  • The standard size of TF card / microSD is 15mm x 11mm x 1mm.
  • The measurement size of the standard SD card is 32mm x 24mm x 1.4mm.

4. Different Structure

On the other hand, if you look closely at the entire design, you will see that the ribs * on the back are also arranged in a different way. (The ribs protect the metal contacts and reduce the potential for damage due to static electricity, scratches, etc.)

5. Different Security

Return to the card design. Popular SD cards are usually designed using lock switches, while TF cards are not. This is called a write protection switch. By sliding the switch to the “locked” position, you can prevent data from being changed or erased by others.

Therefore, due to the design of the lock switch, the SD card is much more secure with respect to data security. Still, if you want to protect a TF card that does not directly support the write-protect notch, you can insert it into a full-size adapter that does support it.

6. Different Definitions

SD cards are a new generation of memory cards based on semiconductor flash memory. TF cards, on the other hand, are relatively small flash memory cards that use SanDisk’s latest NAND MLC technology and controller.

7. Different conversion

Can I use an SD card instead of a TF card? Impossible. You cannot simply use an SD card with a host device that allows a TF card connection.

On the contrary, you can convert the TF card to an SD card using the appropriate card adapter. When you insert the TF card into the adapter, the device will recognize the TF card without any problems.

8. Different applications

TF cards are mainly for mobile phones to expand storage. Due to the increase in mini-volume and capacity, it is becoming popular with some GPT devices, portable music players, and other flash memory disks.

Because they are larger than TF cards, SD cards are typically used in a large number of portable digital devices, such as digital cameras, DSLRs, and handheld game consoles.

9. Different capacity

So far, you can buy TF and SD cards of various capacities on Amazon or other e-commerce websites.

  • TF card: 128G 64G 32G 16G 8G 6G 4G 2G 1G 512M 256M 128M
  • SD card: 512G 128G 64G 32G 16G 8G 6G 4G 2G 1G 512M 256M 128M

10. Different price

In theory, under the same make, brand, capacity, and speed, the price of the SD card will be higher than the price of the TF card.

Why is the TF memory card different from the MicroSD memory card?

Is the difference between the TF memory card and MicroSD memory card only the name? SD cards were formerly called TF or TransFlash cards, but MicroSD is a popular name and is commonly used to identify cards.

SanDisk Corporation has renamed TF Memory Card to a MicroSD Card, so there is no other difference between these two cards. It was released in 2014 because TF memory cards and MicroSD memory cards are somewhat similar and are considered identical.

Both TF memory cards and MicroSD cards are available with the same storage capacity. You can purchase both cards at 128 MB, 256 MB, 512 MB, 1 GB, 2 GB, 4 GB, 6 GB, 8 GB, 16 GB, and 32 GB. Regarding storage support, there is a difference between TF (TransFlash) memory card and MicroSD memory card. MicroSD cards do not support 64 GB of storage capacity, but TF does. This is a big difference between these two cards.

What is the difference between a MicroSD and a TF card

The TF memory card has been renamed the Micro SD card, but there are still some differences. In addition to storing data, Micro SD cards can perform some other functions that are not related to memory.

For example, the Micro SD card supports SDIO communication, so you can use the Micro SD slot to facilitate GPS tracking on satellites and short-range digital communication technologies such as short-range wireless communication and Bluetooth.
