Are you suggesting me to purchase a Toshiba HDD from the lot you have? Because, going by your offered solution, the cost comes up to Rs. 1,100 (inclusive of the case)
Now, I easily found a genuine 250 GB HDD on the internet that cost just the same but with 70 GB less (which I don't foresee using anyway) as this HDD is only for GTA 5, BF4 and Call of Duty: Advance Warfare.
An alternate solution is just purchase a 120 GB Xbox 360 Fat HDD and use it by removing it from the case. This costs about Rs. 250 to 380.
I can even skip the whole HDD purchase by opting to use a flash drive but BF4 won't work.
The reason I'm looking for Genuine HDD is just to save the time instead of opting for the time consuming route.
