HDD Duplicator Deluxe (HDUS325DX)

About the 1:1 HDD Duplicator Series

This family of Addonics 1:1 HDD duplicator is an economical and simple to use one to one hard drive duplicator solutions. The basic model copies from any 3.5" SATA hard drive to another 3.5" SATA hard drive and the Deluxe model can copy from a 3.5" or 2.5" SATA hard drive to another 3.5" or 2.5" SATA hard drive. There is no computer needed or complex software to operate. Just open the doors on the two drive bays, load your master hard drive to the drive bay on top and another hard drive of capacity equal or larger than the master drive to the bottom drive bay, lock the drive door and push the start button to start the copying process.

Besides the duplicating function, this Addonics duplicator is also a convenient drive sanitization tool to wipe clean any sensitive data stored on any hard drive. You can sanitize both source and target drives all at one time using the SECURE ERASE or the OVERWRITE function up to 7 passes to meet the DoD standard.
