Manufacturer description

The StarTech.com Standalone Hard Drive Duplicator is a dual bay SATA dock that clones drives without a computer. Put a source drive in one bay and a target drive in the other, and it makes a sector-by-sector copy of 2.5- or 3.5-inch SATA HDDs and SSDs at up to 28 GB/min. Because it copies every sector, including empty ones, the clone works with any file format or operating system. That makes it useful for drive migrations, imaging new machines, and recovery work. When you are not cloning, connect it to a computer and it works as a USB to SATA docking station. You can reach either drive over…

Frequently Asked Questions

Do I need a computer to clone a drive with this StarTech.com duplicator?

No. Standalone mode clones one SATA drive to the other without a computer. A computer is only needed if you want to use it as a USB docking station.

Can I clone a larger drive onto a smaller SSD?

No. The target drive must be the same size as the source drive or larger, because the duplicator copies the whole drive sector by sector, empty sectors included.

How fast does it clone?

StarTech.com rates standalone duplication at up to 28 GB/min. Since every sector is copied, the total time depends on the size of the source drive, not on how much data is on it.

Will it work with NVMe or M.2 SSDs?

No. It supports 2.5- and 3.5-inch SATA HDDs and SSDs, and it is backward compatible with SATA I/II. Older IDE drives need the SAT2IDEADP adapter, which is sold separately.

What connections and accessories come in the box?

The box includes 3 ft USB-C and USB-A cables and a universal power adapter. The dock connects to a computer over USB 3.2 Gen 2 (10 Gbps), and its drive bays run at SATA III (6 Gbps).
