This File Transfer Time Calculator is used to determine the approximate time that a file would take to transfer over a particular interface . The speeds are optimistic because the actual inferface will be slowed down by overhead (ex: requests for the information, syncs, ...), more than one transfer at a time, and the interface not performing at the standard speed.

^*11024 is most used. The 1000 byte conversion is mainly used by hard drive manufacturers because it makes it look like the drives hold more.

^*2From USB3.0 specification: "it is realistic for 400 MBps or more to be delivered to an application." - from section: 4.4.11 Efficiency
