I have been using Seagate expandable HD of 1.5 TB portable since 2 years back. earlier I was failing to manage space on my laptop which its self-contain 500GB, inbuilt HD. I always loved to call myself movies freak I love to build a collection of different movies from wherever and whatever I got. but because of lots of memory exhausted from my laptop I have to delete some of the very valuable movies, data and sometimes pictures. this always made me saddened when I erase them from my drives. but after Seagate, I can manage my data effectively and efficiently, its data transfer rate s 3.0 which makes it compatible with I-5 and I-7 new generation processors plus I have never got any technical issues so far.so from my side its highly recommendable product and worth to its price. I always love to carry my Hard disk every time when ever I go just to watch any movie, listening songs and sometimes cherishing old memories by visiting old photographs.
