Product parameters: Data transfer rate: 10 (MB / s) Maximum reading speed: 29 (MB / s) Maximum write speed: 20 (MB / s) Product interface: USB 2.0/USB3.0 Shell material: Metal Product weight: 10 (g) Color: silver Package Included: 1x USB Flash Drive Regarding copying a folder is slower than copying a single file: When copying a single file the system only needs to build the index. When copying a large number of fragmented folders each file needs to be indexed so it takes a long time. And executing multiple tasks at the same time also increases the computer load causing channel congestion and slowdowns. Notes for copying files over 4GB: For better compatibility with the operating system the default file system of the U disk is FAT32 and the maximum unit file is 4GB. If you need to store a single file over 4GB it is recommended to reset the file system by: 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. Click Start to finish. Note: About the product (displayed capacity ≠ actual marked capacity): The capacity algorithm of flash memory and computer is different (flash memory 1g=1000m computer uses binary algorithm 1g=1024m). In addition the firmware inside the U disk also takes up a small amount of space. Therefore there will be a certain difference between the display capacity and the nominal capacity of the U disk which is a normal phenomenon. The picture may not reflect the actual color of the item because of different photographing light and display monitor.Thanks for your understanding.
