What Is A TF Card

For mobile phone users, it's not strange to see a very tiny and thin extensible memory card, and that' s called a TF card.

A TF card is the smallest memory card in size, we can say that. TF represents TransFlash, which was jointly developed by Toshiba and SanDisk in 2004, and later the name was changed to micro SD card after the acquisition of the SD Association at the end of the same year. TF card then officially became a member of SD products.

You see, Motorola was the first mobile phone to contain a TF card. A few years later, its competitors began using microSD cards as well. The modern Android phones are gradually giving upon such expandable storage, but Samsung still adopts a micro SD card these days. Though the TF card is rarely seen on mobile phones, it shows up on other compact digital devices, such as dashcams, flying drones, or GPS devices.

Thereof, the following names/texts all suggest the very type of TF card:

TF card = T-Flash = TransFlash = micro SD = microSD

What Is An SD Card

Earlier born than the TF card, the SD card (namely Secure Digital Card) is released in August 1999, by Panasonic, Toshiba, and SanDisk. It's a new generation memory device based on Semiconductor Flash memory.

When it comes to talking about how to choose an SD card, many of us tend to include a microSD card in this category. You should not mix the two concepts again because the microSD card is a de-facto TF card, and it differentiates the SD card by the heading "micro" in the first place.

Admitting that SD card is ultra-small, portable and lightweight, it outranks TF card in dimensions and generally fits itself in some bigger digital devices, such as digital cameras, digital personal assistant (DPA), multimedia players, and sometimes a desktop or laptop has a slot for an SD card!

What's The Difference Between TF Card and SD Card

To get you quickly understand TF card vs. SD card, we reviewed 10 aspects to distinguish the two types of memory cards by their storage, size, price, etc. By figuring out the difference between TF card and SD card, you can decide which memory card applies to your case, and how to use it properly on your digital device.

1.Different Names

Indeed, either type owns its unique identity.

TF card is a flash memory card, with other names that are familiar to us, T-Flash, TransFlash, and microSD. 

SD is the abbreviation of Secure Digital, and it is a proprietary non-volatile memory card format. Due to many capacity standards up till now, there developed its derivatives, including SDHC, SDXC and SDUC.

2.Different Origins

TF card was originally put into the market in 2004 and it was not a member of SD products then. SD Association acquired it from Motorola and SanDisk in the same year. Other memory cards taken by SD Association include miniSD and SD cards.

Nowadays belongs to the same SD products of SD Association, but SD card is initially carried out by Panasonic, Toshiba, and SanDisk in August 1999.

3.Different Size and Appearance

On one hand, we can find out the difference by dimension.

The standard size for a TF card/microSD is 15mm x 11mm x 1mm;
And the measured size of a standard SD card is 32mm x 24mm x 1.4mm.

4.Different Structure

On the other hand, when you carefully look into the whole design you'll see the ribs* on the backside are also structured in a different distribution way. (Ribs can protect metal contacts to reduce the possibility of damage caused by static electricity or contact damage such as scratches)

5.Different Security

Back onto the card design again. The prevalent SD card is usually designed with a lock switch while the TF card is not. It's called a write protection switch. By sliding the switch to the "Lock" position can protect data from being modified or erased by others.

Hence, due to the lock switch design, the SD card is much more secure for data security. Nevertheless, if you want to secure the TF card which does not directly support a write protection notch, you can insert it into a full-size adapter which does.

6.Different Definition

SD card is a new generation of memory cards based on Semiconductor flash memory. Whereas the TF card a relatively small flash memory card that adopts the latest NAND MLC technology and controller of SanDisk.

7.Different Conversion 

Can you use an SD card instead of a TF card? No way. You cannot simply use an SD card on a host device that allows for a TF card connection. 

On the contrary, you can turn a TF card to an SD card, with the help of a proper card adapter. Put the TF card into an adapter, your device will recognize the TF card without any problem.

8.Different Application

TF card is mainly for mobile phones to expand storage. Thanks to its mini volume and increasingly enlarged capacity, it's more and more popular to see on some GPT devices, portable music players and other flash memory disks.

Being bigger than TF card, SD cards are generally used on quite a lot of portable digital devices, such as digital cameras, DSLRs, handheld game consoles, etc.

9.Different Capacity

So far we can buy TF cards and SD cards on Amazon or other eCommerce websites with a range of capacities:

  • 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

Theoretically, under the same manufacturer, brand, capacity, and speed, the price of an SD card is higher than that of the TF card. 

How Does TF Card Work

By walking through the long comparison of 10 primary differences, I believe that you should have a clear brain now. But what is the best TF card on the market?

Basically, keep in mind what your requirement is, and this is an essential step to start browsing a shopping site and search for the desired product. If you're using a card for your mobile phone then it will work with almost all microSD cards, you can find one within budget. Don't deceive yourself buying those cheap and nameless products, or else you'll spend twice money to repair a damaged SD card to save data!

Those brands are renowned and provide you with responsible customer services: SanDisk, Toshiba, Samsung, Lexar, Kingston, Transcend, Sony, etc.

Another noted point to choose a satisfactory TF card is the "class speed". TF cards and SD cards have a different class rating from 1 to 10. The higher speed cards signify higher speed and performance. If you're not recording in 4K, the speed might not be so important, but a faster-fated card will still be useful if you're using the card to expand the storage in a smartphone or a camera because faster read and write speed means fluent performance, and that will make the device more responsive.

Considering the price and purpose of how to choose a right SD card, here comes the most critical process, how does TF card work on a certain type of digital device?

To make your phone, dashcam, drone or a GPS device correctly detect, read and write data on the microSD card, you need to format it to a proper file system. A file system controls how data is stored and retrieved. Without a file system, information placed in a storage medium will exist without significance.

What file system should you allot to a new card? SD Association offers a format utility for users to format a memory card, and you can refer to this classification to achieve the best performance regarding different capacities of the microSD card. 

  • Up to 2GB: FAT12/16
  • More than 2GB and up to 32GB: FAT32
  • More than 32GB and up to 2TB: exFAT

So far, the most commonplace microSD card is within 32GB on a phone, and a 2GB microSD card is for a dashcam. Extreme large size cards are usually for digital cameras. If you prefer a user-friendly, intuitive, and powerful disk format utility that supports all file system formats on a storage medium, EaseUS Partition Master Free is a good assistant.
