Can I use USB flash drive duplicators with external hard drive enclosures?

Although the USB flash drive duplicators are intended for use with USB flash drives, they can be used with external hard drives. Note: Due to the slower copy speed of the USB flash drive enclosures, using an external hard drive as the source of the copy can take a considerable amount of time. USBDUP12 and USBDUP15 both copy at 1.5 GB per minute. Therefore, if you use a 1 TB external hard drive as the source of a copy, it would take roughly 11 hours to complete.
