Hello.friends, I am writing a view about sony pendrives, sony pendrives are manufacture by sony company but these are all not perfect.Only its design was quite good but internally it was the worst pendrive. The transfer speed for sharing the files from one place to other place is very slow and it very costly compare to other brand.It looks very good but the performance of the pen drive is very bad.I am totally disappointed by this pendrive. I have to say from my experience just stay away from sony in pendrives. Thanks.
