USB Flash Drive Duplicator Review Receives A+ CD and DVD duplicators have been popular for so long; however, with the optical drive no longer sold in nearly all computers, the only device left for moving files around are USB flash drives. With that in mind, we took a look at a USB flash drive duplicator and wanted to provide observations and opinions. The benchmark we are comparing the USB duplicator to is the speed compare to burning a DVD. With a 16X DVD recorder it will take between 6-7 minutes to burn a full disc, which is 4.7GBs. A common size DVD duplicator is seven optical drives which means seven copies every seven minutes. However, today’s file sizes are getting larger and a data load can easily be over 5GBs. A dual layer DVD which is 8.5GBs would take nearly 27 minutes.
