In field data acquisition and forensic duplication, the ability to copy data to two independent media types (dual USB or USB + SD card) improves workflow redundancy. The SData Tool V100 (“V100”) claims to support “double USB or SD card space,” meaning it can either:

This paper tests those claims.

The SData Tool V100 fulfills its core promise: redundant copying to two USB drives or one USB + one SD card. Limitations include:

Potential use cases: field photography backup, small-scale forensic imaging, industrial data logging.

Result: The V100 treats two 128GB USB sticks as a single 256GB logical volume. You have effectively doubled your target space without buying a larger drive. This is perfect for cloning a 250GB SSD.

Pro Tip: Ensure both USB drives are the same make and model. If one drive is slower, the V100 will throttle the faster drive to match, but the total addressable space remains the sum of both.


Consider a typical use case: You are using the SData Tool V100 to clone a 64GB SD card from a dashcam. You insert a 64GB USB drive as the destination. Logically, it fits—but it doesn’t. Why?

By learning to double your effective space, you can store two 64GB images on a single 64GB drive, or use a 128GB SD card to handle 256GB of source data.


To understand the functionality of SDATA Tool, one must understand how operating systems interact with storage media.
