Q&A The 64GB USB Flash Drive I bought shows that the actual capacity is only 58GB on the computer, is it normal? Answer: It is normal. Because the capacity after production of flash memory products is usually calculated as 1MB=1000KB,1G=1000MB, but the operating system uses binary arithmetic; 1MB=1024KB,1GB=1024MB, so there is a certain diffe rence between the displayed capacity and the standard capacity of flash memory products. So the 64GB USB Flash Drive does not actually reach 64GB, most of them are about 58GB. This is within the normal range. About reading and writing speed Answer: The read and write speed of the USB Flash Drive is related to the USB interface of the computer, the size of the copied file, the format of the USB Flash Drive, and the computer operating system. The reading and writing speed will be different under different usage conditions, which is a normal phenomenon of USB Flash Drive usage. Storage Format Description Answer: The default format of the storage device is FAT32. Most devices that use memory cards (cameras, recorders, etc.) only support the FAT32 format. If you need NTFS or exFAT format, you need to convert the format on your computer or other devices. About heating phenomenon of USB Flash Drive Answer: It is normal for the USB Flash Drive to heat up. When the USB Flash Drive is powered on, it will transmit and read data, resulting in emitting heat of the electronic components in the USB Flash Drive, and the chip will generate heat according to factors such as the time it is powered on, the frequency of read and write operations, and the speed of reading and writing. Because metal has good thermal conductivity and heat dissipation, it is normal for the metal USB Flash Drive to heat up, and it is not a quality problem. The USB Flash Drive chip can withstand a high temperature of 85C. Please rest assured that the product will not be damaged due to heat, and you don’t have to worry about it. About copying folders is slower than copying single files Answer: When copying a single file, the system only needs to create one index. When copying a large number of fragmented folders, each file needs to be indexed, so it will take a relatively long time. And if multiple tasks are performed at the same time, it will also increase the load on the computer, resulting in congestion and slowdown. Instructions for copying files larger than 4GB Answer: In order to be better compatible with the operating system, the default file system of the USB Flash Drive is FAT32, and the maximum unit file is 4GB. If you need to store a single file exceeding 4GB, it is recommended to reset the file system in the following way: 1. Connect the storage product to the computer; 2. Right-click the partition and select Format; 3. Select the exFAT format in the file system option; 4. Just click "Start" and "finish." specification: 1. USB connection,support Hot plug & Play. 2.
