Just purchased a Western Digital Elements 1TB external hard disk on ebay for Rs 4700, I had to admit that after intense searching, this was the best price I could find .

Just plug it into a USB port and you’re up and running instantly.
USB powered - These drives require no power adapter; they are powered directly through the USB cable.
Compact design - Weighing in at only a few ounces, these small drives fit easily into a pocket or purse.Very easy to carry along, almost a size of a Blackberry .
