Worse product Read Speed= 34 Mbps and write speed= 23Mbps. It’s delicates product because the real one has R/W speed is above 108 Mbps which my friend had. It has very bad quality. It the transferring speed is not as much as I had expected. During use it heat like hell worse product don’t buy. It give only 28Gb of space 4Gb is not seen anywhere.
