"Transferring large amounts of data from one computer to another can sometimes be a hassle. If you are using a flash drive you might have to take several trips back and forth between computers and if you are using an external hard drive, it might take a while. A nice alternative is to simple copy the data onto an internal hard drive and then just move the hard drive to the other computer. You might be thinking that this will end up being a lot of work since you are going to have to take the computer apart and unplug everything, but no, you don't have to do any of that. With the iStarUSA T-7M1-SA Removable Hard Drive Rack which will mount into a 5.25" drive bay, all you have to do is simply press a button and the hard drive comes right out with no problems."
