I Purchased a 16 GB Sandisk Cruzer Blade pen drive a few weeks ago. Honestly, I must say it’s the worst pen drive I have ever seen. It’s the most slowest thing ever really.Writing a 4GB file onto the disk takes about 15-20 minutes, I guess if I wanted to fill up the drive, it would probably take me 2.5 hrs. I thought it will deliver good transfer rate, but I am highly disappointed by the rate it has delivered. Its really sad to see company like SanDisk offer such low speeds and even after few months the disk was corrupted. I asked for customer support but no one helped. I am utterly disappointed at this purchase, and will definitely not be recommending this product to ANYONE. I don’t think I will ever go in for another Sandisk product in the future.
