Flash media doesn’t use a unified standard like optical discs, so each USB flash drive you get could have slight or significant variations, even when you purchase the same brand. Because flash is meant to be copied over and over again across a number of memory chips, it’s not uncommon for some of the memory to become corrupted during the copy process. What that means is that if you are copying a master USB flash drive to multiple USB flash drives, the master USB flash drive is constantly be read over and over again to make the copies, which has the potential of some of the memory to be altered. That means that if the master is altered, even slightly, it could negatively impact all the copies you’re making. Most experienced duplicators will use the copy and compare function in order to ensure the copies match the master, which should ensure perfect copies. However, if the master is altered during the duplication process and becomes corrupted, then the copies will match that corruption and therefore pass the compare process. This could lead to the operator believing they made all successful copies but in reality they potentially created a sizeable number of bad drives that they could send out to potential customers.

Vinpower created an excellent method to prevent this catastrophy from happening by dedicating a separate USB port as a compare only port. By having a dedicated compare only port, you’ll insert 2 identical master USB flash drives into the source port and the compare only port and then when you make copies and run the compare feature, the source port drive will send the duplicated content to all the waiting USB flash drives and then those copied drives will be compared to the separate compare only drive. That way, if there’s any variation between the two masters it will be picked up immediately and those copied USB flash drives will be failed to prevent the user from using the corrupted drives before they are accidentally given to the customers. This dual copy and compare process does not take any extra time but gives the operator complete piece of mind that the copies they made are 100% authentic identical copies of the original intended master content.

So if you want total piece of mind and assurance that your USB flash duplicated drives contain the content you intended, then you need a Vinpower USB duplicator that offers the dual copy and compare ports.
