Suggested by my friend over the likes of Seagate, I bought this external Hard drive - 1 TB online. The device has 3 year manufacturer warranty.
It has been around 3 years and this device is giving awesome performance. Price is also reasonable. It is available in three colors Black, Blue and Red. I bought Blue color. Although these days red and blue colored drives are expensive than black ones. Western Digital has another variant for the same capacity WD - My passport which is expensive than WD Elements by around 500 rupees but is prettier than Elements.
