TF Card Is a Very Small Flash Memory Card, Which Is Mainly Used in Mobile Phones. However, Due to Its Small Size and Increasing Storage Capacity, It Has Been Used in GPS Devices, portable Music Player and Some Storage Disks. Its Volume Is 15mm X 11mm X 1mm, Which Is Almost Equal to the Size of the Finger and Is Now a Tiny Flash Memory Card. It Can Also Be Connected to the SD Card Slot through SD Adapter.

 

* If 3.0 Card Reader 3.0 Interface Is Used, the Test Data Will Be Better. The Actual Speed Depends on the Device Used and the Document Size.

 

Special Reminder

 

The Actual Capacity of the Memory Card 2GB Is about 1.85GB, Because the Computer Uses Binary Manufacturers to Produce 10-Bit

 

(the Computer Is 1MB = 1024kb, the Manufacturer Is 1MB = 1000kb) Calculated,

 

2GB Is about 1.83GB, 4GB Is about 3.7GB, 8GB Is about 7.3GB, 16GB Is about 14.6GB

 

Class Level

 

Class Level Is Also an Important Symbol of TF Card. It Is a Quantitative Symbol of Transmission Speed. Memory Cards of Different Levels Can Meet the Needs of Different Users.

The Class Level Is Related to SDHC. for Example, The SDHC Memory Card Must Have a Capacity of More than 2GB and a Transmission Speed of at Least Class 2.

How to Identify True and False Cards?

 

Currently, There Are Many Fake Products on the Market, and Flash Memory Such as SD Card, U Disk, TF Card, and Memory Stick Can Be Upgraded,

 

Upgrade Is to Upgrade the Capacity of 1G Or 2G (Or Smaller, Such as 128M,256M) to 4G, 8G, 16G, 32G, Or More,

 

The Actual Capacity Is Still 1G Or 2G, and the Buyer Cannot Judge Whether to Upgrade the Product through the Computer's Naked Eye.
 
Currently, an Effective Method Is to Use H2testw Or Mydisktest Software for Full Verification!

 

 

A Simple and Effective Way to Check Whether the Card Is Sufficient Is: for Example, a 14.9G Card Copies about 14G of Data.

 

(Files, Songs, Movies) Go in, Then Delete the Hardware in the Lower Right Corner of the Computer and Pull out the Card Reader,

 

Insert the Card Reader Again to Copy out the Data to See If the Data Is Normal,

 

If the Actual Capacity Is Reached,

 

If the Memory Card Is Upgraded Or Expanded, It Is Only the Actual Capacity (128/256/512/1G/2G)

 

The Upgraded Capacity Can Be Used, and the Materials Copied Later Are Virtual and Cannot Be Extracted Or Damaged!!!
