The 1:4 Aleratec Blu-ray DVD CD Tower Duplicator SA allows you to duplicate CDs, DVDs, and Blu-ray easily and quickly, using either the included removable 2TB hard drive, your own PC, or by reading from one of the source trays on the front of the unit. It also uses USB 3.0 compliant architecture, giving you optimal transfer rates.
The USB 3.0/2.0 connection allows you to drag and drop files from your PC directly to the internal hard drive. There is also support from a variety of source formats, including simply copying your contents onto the internal HDD without creating an image file (only supported for DVDs and CDs).
If you're not utilizing the generous hard drive space or your own PC, you can always use one of the trays as a source, drop your CD/DVD/BD in there, and make three flawless copies from that disc. You can easily duplicate ISO image files, NRG image files, and in some cases, directories and files not packaged into a disc image files - again, this only applies to DVD/CD duplication.
