Difference between Tf card and SD card.
Difference between Tf card and SD card. - Table of contents:
In the vast sea of memory cards, how do you tell which memory card you should buy, or put in use for a certain type of digital device? Given that you’ve been already mixed up in your mind with their names, e.g. CF card, Tf card, SD card…
Tf card and SD card are two common memory cards, which are widely used in small electronic devices such as smartphones, digital cameras, game consoles, etc. are also different.
What is a Tf Card?
Tf card (TransFlash card), also known as Micro SD card, was jointly developed by Motorola and SANDISK and launched in 2004. It is an ultra-small card (11x15x1mm), and the volume is only a quarter of the SD card, so the Tf card can be regarded as the smallest memory card.
Meanwhile, Trans-Flash Card is a member of SD Card products. In addition, the Tf card can be used with an SD adapter, compatible with any SD card reader. The Tf card can also be used as an SD card after being converted by the SD card adapter.
T-Flash cards are the smallest flash memory cards on the market and are suitable for a variety of multimedia applications. Since the Tf card adopts the SD structure design, the SD Association officially changed its name to Micro SD at the end of 2004 and became a member of SD products.
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?
SD card (Secure Digital card) is a new generation storage device based on semiconductor flash memory. It was jointly launched by Panasonic, Toshiba, and SanDisk, and released in August 1999. Due to their small size, fast data transmission speed, hot-swappable, and other excellent features, SD cards are widely used in portable devices, such as digital cameras, digital personal assistant (DPA), LCD media player, and sometimes a desktop or laptop has a slot for an SD card!
What is the difference between Tf card and SD card?
1. The name is different
SD card, that is, a Secure Digital Memory Card, translates into a secure digital card in Chinese.
Tf card (T-Flash), also known as MicroSD, is a memory card. It was later renamed TransFlash, and MicroSD because it was adopted by the SD Association (SDA). Other memory cards taken by SDA include miniSD and SD cards.
2. Different definitions
SD card is a new generation storage device based on semiconductor flash memory.
Tf card is a very small flash memory card, which adopts SanDisk’s latest NAND MLC technology and controller technology.
3. The origin is different
The SD card was jointly developed by Panasonic, Toshiba, and SanDisk in August 1999.
Tf card is the latest generation memory card specification jointly launched by Motorola and SanDisk, which was launched in 2004.
4. Different sizes and appearance
Tf cards and SD cards are designed in different sizes. The volume of the SD card is 24mm x 32mm x 2.1mm; the volume of the Tf card is 15mm x 11mm x 1mm. Also, they look different. Please see the picture below.
5. Different applications
SD cards are widely used in portable devices such as digital cameras, personal digital assistants (PDAs), and multimedia players.
Tf card is mainly used in mobile phones, but due to their small size, with the increase in capacity, Tf card has gradually begun to be used in GPS equipment, portable music players, and some flash drives.
6. Tf card can be converted to an SD card
Tf card plug adapter (adapter) can be converted into an SD card, but an SD card generally cannot be converted into a Tf card.
7. Different Memory Storage
SD card offers these capacity choices: 128G 64G 32G 16G 8G 6G 4G 2G 1G 512M 256M 128M. While Tf card offers these capacity choices: 128G 64G 32G 16G 8G 6G 4G 2G 1G 512M 256M 128M.
8. Different Security
SD cards have a write-protect switch. There is no Tf card, but the Tf card can be converted into an SD card through the card sleeve.
