Tom's Hardware Writes: "In times of increasing memory capacities, backing up your data isn't quite as easy as it was a few years ago. Optical media is totally unsuited for saving the volumes of data that are generated today. Well, what could be easier than backing up your data by simply copying the contents of an internal drive to an external one?
Hard drives are available at low prices, around 10 cents per gigabyte, and there are two primary ways of connecting an external drive to a computer: USB 2.0 and eSATA. We have already introduced some of the adapters that make connecting an external hard drive to a PC easier in this story on storage accessories."
