Firstly surprise to see this miniature at this price that is Rs. 649 bought it two days ago and it arrived today. I started testing this pendrive and i was totally shocked regarding its read and write speed. results - 1. copying 1.8gb file from laptop to pendrive speed = 40mb/s average 2. copying 1.8gb file from pendrive to laptop speed = 290mb/s average 3. cut-paste 2.8 gb file from laptop to pendrive speed = 43mb/s average 4. cut paste 2.8 gb file from pendrive to laptop speed = 80mb/s average p.s (All these results are based while using pendrive in 3.0 usb slot in laptop.) Also you have to put your finger for support behind the handle to push the p.d into the usb slot otherwise it will slip backwards.
