The data transfer rate (DTR) is the speed that data can be transmitted between devices. The (DTR) is measured in

kilobit, megabits and gigabite. High transfer rates are normally reguested because audio and video file size  can be quite large. 

 

More and more consumers are moving to cloud base storage. But there are many in the business who like to use hard drive systems such as RAID. These systems consist of numerous drives linked together. 

 

Transfering your data will give you a backup you can immediatly  access.
