Sandisk is a very reputed brand when it cones to pendrives, and looking at the prices we are compelled to buy the PD from thia brand. The same happened with me.
I purchased cruzer edge 16 GB Pendrive at just 350rs. which I thought was a very profitable deal. But the PD was not performing as I expected. The reading and writing speeds were comparably low compared to my previous Hp PD. Also after using for around 2 months the pd was not getting detected in pc, while other pds were working fine.
I suggest to buy pd from other brands even if you have pay some extra bucks
