I bought it from amazon in a flash sale before it a seagate expansion 1 tb hard disk had just crash with my all data of last 4 years once I feel like I m dead.
When I see it I feel surprised it is So light weight than my older hd and when I took backup of my friends laptop it give 105 mbps in isb 2.0.
What more than it you want from a portable hd it is compact it is light weight. Not really light weight its weight os almost negligibe
