We then get an answer in seconds, which then can be further converted to minutes and seconds.ĭuration = (500 * 8) Mb / 15 Mbps = 266.67 seconds = 4 min 26 sec Current SSDs have transfer rates that can push USB 3.0 to its limits, but not 3.1 (yet). Note that the transfer speeds also depend on the device in use in addition to the bus type and USB ports and cables. However, there are few devices that are capable of such high data transfer speeds. When comparing 2.0 and 3.0 there are a few major differences.First the transfer rates: USB 2.0 offers transfer rates of 480 Mbps and USB 3.0 offers transfer rates of 4.8 Gbps - thats 10 times faster. This rivals the speed of Ethernet and the original Thunderbolt. We need to multiply 500 MB by 8 to convert the data size to megabits. The data transfer speed of USB 3.1 is incredible 10Gbps. All we need to do to use the above equations is to convert to a common set of units.įor example, let's calculate the time it will take to transfer a 500 MB file over a 15 Mbps data connection. A byte consists of eight bits, so one megabyte is eight times the size of a megabit.

This cable comes with a standard USB Type-A connection that connects to desktops, notebooks, and tablets, and a USB 3.0 micro-B interface is on board to power and transfer data for portable storage drives. You'll see computer files usually in units of megabytes (MB) or gigabytes (GB). Transfer data quickly and reliably with the 15 orange TetherPro USB 3.0 Male Type-A to USB 3.0 Micro-B Cable from Tether Tools. ISPs (Internet Service Providers) usually sell you internet bandwidth in units of megabits per second (Mbps or Mbit/s). You can rearrange this equation to find the duration of the data transfer:īefore we go ahead and use these equations, we need to pay attention to the units. The formula to calculate the data transfer speed is:
