There's more than one way to make a hard drive copy, but when time is money, a HDD duplicator is the best option. It's faster and simpler to utilize a HDD duplicator when duplicating multiple disks. A hard drive duplicator is designed specifically for making one or more copies, often without tying up a computer that might be needed for other functions. Using HDD duplicating software packages are typically much more complicated and time-consuming to use compared to the few button pushes it takes to clone an HDD using a duplicator.

Nowadays, it only takes minimal effort for end users to backup, archive and duplicate data on a HDD by utilizing HDD Duplicator.

For some organizations and individuals that work with hard drives on a regular basis turn to HDD duplicators for fast and accurate copies, increasing productivity and reducing costs. JMicron provides a simple, fast and reliable drive copying solution without using computer. The controller is suitable for any SATA HDD to be connected with the source and target port.

The duplicator conducts data verification after each duplication work completes, while the machine can also provide additional functions, such as:

  • HDD formatting
  • HDD sanitizers
  • Works as dock for multiple HDDs when directly connect to PC host
