TF cards or microSD cards are a type of digital memory card used for storing digital data. The SD association adopting and rebranding TF cards as microSD cards aligned them with the already popular “SD” standard, allowing them to be used across a wide range of electronic devices. TF card’s biggest selling point was their small size, measuring in at just 15mm x 11mm x 1mm. These dimensions meant they were easy to store, and could be used in portable devices like smartphones, action cameras, and wearable technology.
However, this small size didn’t limit the TF card’s storage capacity, which typically ranges from 4GB to 256GB, with some extended capacity cards able to store more than 1TB of data. TF cards also have quick transfer speeds, so users don’t have to wait a long time while their data moves to the card, which is especially handy when transferring large files like high-definition videos or video games. You can determine how fast a TF card is based on its speed rating: Class 2, 4, 6, and 10, with class 10 cards being the fastest and class 2 cards the slowest.
TF cards are known for their longevity, with the typical card able to store data for up to 10 years, allowing users to safely and securely store important data without worrying about losing it. They’re also relatively inexpensive compared to other storage options, and prices have decreased over the years, even as their storage capacity has increased.
