1 to 39 USB 3.0/3.1 Duplicator & Sanitizer - Standalone High-Speed

In this review we look at the 1 to 39 USB 3.0/3.1 duplicator and sanitizer, a standalone device intended for technicians, small media houses, IT departments, and anyone who needs to copy or erase many flash drives without a PC. The bottom line: it shines for bulk USB cloning because it copies bit-for-bit at a sustained 18GB per minute and works without a computer, making repetitive duplication runs fast and predictable for users who value speed and simplicity.

Key Features

• Standalone operation: No computer or software required, so cloning and sanitizing tasks can be performed in the field or on a bench with minimal setup.
• High transfer rate: Copies at up to 18GB per minute (300MB per second), keeping large batches moving quickly even when many targets are loaded.
• Bit-by-bit duplication: Performs exact sector-level copies from a source USB 3.0/3.1 flash drive, preserving file structure and boot sectors.
• Synchronous and asynchronous modes: Offers both copy modes so users can prioritize speed or individual drive handling depending on workflow.
• Warranty and support: Includes 1 year parts, 3 years labor, and lifetime technical support for long-term reliability and serviceability.

Who It's For

This device is best for IT administrators, media distribution teams, forensic technicians, and small businesses that regularly duplicate or sanitize large numbers of USB flash drives and need a predictable, fast process without tying up a PC. It also fits environments where multiple identical media need to be prepared quickly for deployment or training.

It is less appropriate for casual users who duplicate drives rarely, or for anyone needing integrated imaging software features beyond bit-for-bit copying and sanitizing; those users should consider software or PC-based solutions that offer more flexible image management.

Pros & Cons

Pros

• Very fast sustained copy speeds up to 300MB per second, which reduces total run time for large batches.
• Fully standalone operation eliminates the need for a host computer and special software.
• Bit-by-bit duplication preserves exact drive contents, including boot sectors and hidden data.
• Long-term support with a 1 year parts and 3 year labor warranty plus lifetime technical support.

Cons

• Some users report mixed reliability in functionality, so occasional troubleshooting or service may be necessary.
• Standalone hardware is less flexible than software tools for custom image editing or selective file copying.

Our Verdict

The 1 to 39 USB 3.0/3.1 duplicator and sanitizer is a strong choice for professionals who need fast, reliable bulk USB cloning without a PC; its sustained 18GB per minute throughput and bit-for-bit copying deliver predictable results and good value when large batches are routine. Buyers who need more flexible image editing should choose a software approach instead.

Frequently Asked Questions

Does this unit need a computer to operate?
It does not require a computer or software; it is designed for standalone operation so duplication and sanitizing can be done directly on the device.

Will copy speed slow when more targets are connected?
According to the manufacturer, the copy speed will remain the same even as the number of targets is increased, maintaining up to 300MB per second.

What kind of duplication does it perform?
The device performs bit-by-bit duplication from a source USB 3.0/3.1 flash drive and supports both synchronous and asynchronous copy modes.
