Internet service is getting faster and cheaper ... but is it now fast and affordable enough to be used as your primary backup system? Backing up files to a USB external drive is different. By using USB 2.0, you can transfer files up to 480 Mbps - I will explain.
Transfer speed is measured in Mbps (Megabits per second). Using a 1 Mbps connection, you can send 125 kilobytes every second. This is not fast enough to receive streaming video in standard resolution. To receive HD (1080p) video streaming, you should have a 20 Mbps connection.
One 2 hour / 1 GB movie uploaded using a 5 Mbps broadband connection can take about 20 minutes or 1.5 hours with 1 Mbps speed. Given that a terabyte has 1,048,576 megabytes, if you could achieve the theoretical 60 Mbps transfer, you could do it in slightly over 4 hours and 45 minutes.
I am designing a system that allows people to back up a huge amount of data for safe storage. The key to this is speed and ease-of-use. The first step is to create a testing method for the file transfer rate. It is a challenging but interesting problem to solve.
