This time I got this external hard drive which impress me very well, its just 2.5-inch, dimensions are 4.5 x 3 x 0.5 inches. I have taken this with on my tours. its easy to carry due to this design which is comfortable and weight is just 5.6 ounces around 200g, which is not heavy to carry. I brought seagate products before and its not expensive, if you talking about seagate brand, I like there quality and service, one of my friend got some issue with there product which they change within 3 days, even when you buy from one of the good online store as far you have warranty card.
