Alex is planning to transfer a 10GB file from her desktop to laptop using a USB3.0 portable HDD. Her desktop PC only supports USB2.0 (12 Mb/s) while her laptop supports USB 3.0 (5 Gb/s). Please calculate roughly how much time it will take for the transfer of this file. You can ignore the time to connect the portable HDD to computers.
Question
Alex is planning to transfer a 10GB file from her desktop to laptop using a USB3.0 portable HDD. Her desktop PC only supports USB2.0 (12 Mb/s) while her laptop supports USB 3.0 (5 Gb/s). Please calculate roughly how much time it will take for the transfer of this file. You can ignore the time to connect the portable HDD to computers.
Solution
To calculate the time it will take to transfer the file, we need to consider the slowest transfer speed because that will be the bottleneck in this process. In this case, the desktop PC only supports USB 2.0, which has a transfer speed of 12 Mb/s (Megabits per second).
First, we need to convert the file size from Gigabytes (GB) to Megabits (Mb) because the transfer speed is given in Mb/s.
1 GB = 8000 Mb (1 Byte = 8 bits, 1 GB = 1000 MB, so 1 GB = 8 * 1000 = 8000 Mb)
So, a 10 GB file = 10 * 8000 = 80000 Mb
Next, we divide the file size by the transfer speed to get the time it will take to transfer the file:
80000 Mb / 12 Mb/s = 6666.67 seconds
To convert this into minutes, we divide by 60:
6666.67 seconds / 60 = 111.11 minutes
So, it will take approximately 111 minutes to transfer a 10GB file from the desktop to the laptop using a USB 2.0 connection.
