Sdata Tool V100 Double Usb Or Sd Card Space Exclusive Official

The device itself was compact, about the size of a thumb drive, with a small LCD screen on one side and two slots on the other - one for an SD card and one for a USB connector. According to the instructions, you could insert either an SD card into its slot or connect it directly to a computer via the USB port. The bold claim was that it could somehow double the storage space of whatever it was connected to.
