Best place(s) to buy a 2.5" HDD in Paris

[NatuNobilis]

I am visiting Paris right now and would like to know the best place(s) to find a 2.5" harddrive for my laptop. Mine broke the day right before my flight, so I had no time to search for it in my hometown in Brazil. Also, I guess it'll be a lot cheaper here than in Brazil.

Thanks a lot for any help.

There is a big place on Rue du Voltaire, which is right in the middle of the city. So start there? It's been well over a year since I was there last though.
