I have bought over three external hard drives over the past ten years, ranging from 1 to 3 TB in size. While all of them were adequate, the larger ones, were slower and they all wore out quickly, from the largest to the smallest. Seagate is not only 2 TB in memory size, it is three times faster than any of the others I have owned. it out-performed them all in every category. It is portable, fast, and does not use an electrical cord but gets it's power from the USB cord that it uses for computer connections, so only one cord needed. Just plug into your computer USB port and its up and running.... that easy. I also recommend a small carrying case to hold the portable drive and it's cord for protection. The Insignia™ - Hard Shell Case for Most Portable Hard Drives - Black, fits it to a tee, and the cheapest on the market, a hardshell covered in cloth. It's superb!!! Five stars for both
