According to the USB Association, USB 3.0 has been renamed “USB 3.1 Gen 1”. The USB 3.1 Gen 1 specification encompasses the USB 3.0 specification and retains a theoretical transfer rate of 5.0 Gbps, which is 10 times faster than USB 2.0. USB 3.1 Gen 1 (USB3.0) is backward compatible with USB 2.0, but the transfer rate will be limited by the USB 2.0 interface.

All storage products will display less than stated memory capacity on a computer. The discrepancy results from different algorithms.

On a computer, 1GB = 1024*1024*1024 = 1,073,741,824 (1024 is 2 to the power of 10, which is the algorithm used by the computer)

For a 32GB pen drive, the computer will calculate it as having capacity of 29.80GB.
32,000,000,000÷1,024÷1,024÷1,024 ≒ 14.90GB.

Also note that each Flash memory may possess innate variances because of its manufacturing process. KINGMAX will therefore adjust the available space on the pen drive to store necessary firmware configurations or system data. Please be assured that we do so at appropriate measures and that your pendrive has the normal capacity.

(1) FAT32 is only supported by memory cards/ pen drives with capacity less than 32GB, and it does not support storing or transmitting any single file that exceeds 4GB in size.
(2) The exFAT file system was released by Microsoft to address FAT32's inability to carry files over 4GB. Also if the capacity of your memory card/pen drive are larger than 32GB, you could format it to exFAT.  It depends on the users' need to choose the file system to format the memory cards / pen drives.

The size limit of an FAT32 single file is 4GB, therefore a movie exceeding 4GB cannot be stored. You may format your USB disk with NTFS format to enable storing single files that exceed 4GB.
