The biggest differences between a duplicator and a PC are: the copy speed and the target volumes of duplicating each time.Speed and efficiency:Software limitations in PC can only allow duplication of one flash device each time. Some software allow simultaneous port duplication, but with the bandwidth divided. Professional duplicators can copy large volumes of targets, with dedicated bandwidths, all at once which increases the production capacity to reach large-scale economy.Format:1. PC Windows can only support the NTFS and FAT formats, but U-Reach duplicators can use the "quick copy" mode which supports Linux ext2/3/4, NTFS, HFS/HFS+/HFSX, and FAT16/32/64. You are able to copy the entire source media to your targeted devices.Risk of virus infection:2. The open structure of the PC creates vulnerability, such as virus infection risks, in all of the devices that are connected. All duplicators has proprietary embedded systems which will safe-guard against virus infections making contaminations, impossible.
