I recently buy HP Pen drive(2.0 V215b) 16 GB at RS. 519 by online shopping, which works more efficiently and I am happy with this product that means the product gives excess profit with low cost. User friendly product, USB 2.0 flash drive, 14mbps reading speed and 4mbps writing speed, supported in Windows, vista, XP, and more. This is very small so you can keep it in your pockets and more important the product gives 2 years warranty. HP gives better support and service of their customers.
