The most important thing to look for in an external hard disk is warranty period. In simplest terms, the longer the warranty, the better it is for you. Eventually, your hard disk is going to fail, so what you have to do is plan a series of purchases where you can keep moving all the data to newer hard disks before the previous ones fail. Then the next consideration is the amount of storage space on the drive. The more data that the drive offers, the cheaper it is per TB. If you want more bang for buck, you also have to spend more money. Another important thing is to check whether the device supports high speed data transfer on USB 3.0 ports. Some older drives do not have support for the latest generation of USB interfaces. Then you can look at the bundled software and extra features. All things considered, these are the best options below. Note that many of these products have seen steeper discounts in the past, and that these are not the lowest prices that they have been available at. In most cases, the difference is of a few hundred rupees. Hard disk prices fluctuate wildly in the market, because of a number of factors. In any case, these are the best deals available at the moment.
