This product is semi-finished and can be wholesale
Interface: USB 3.0
Memory Storage Capacity : 4GB/8GB/16GB/32GB/64GB/128GB
Note:
About capacity: because computer algorithm is different from U disk capacity of the algorithm,computer algorithm 1G B=1024MB, but U disk capacity of the algorithm 1GB=1000MB,so The actual amount of memory is as follows:

4GB = (3.6GB-3.8GB),
8GB= (7.40GB-7.55GB),
16GB= (14.6GB-15.1GB),
32GB= (28.9GB-30.5GB)
64GB= (58.0GB-60.0GB)
128GB=(118.5GB-120.9GB)

Read and write speed: more than 10M/S (transmission speed over a certain relationship with the use of computer).
