HP USB 3.0 64GB Flash Drive - x740W : When i copied 8GB data on to the flash drive using USB 3.0 port on Notebook PC, got a write speed of 23 MB/Sec but it was unusually getting heated up. The measuring device that i used could only measure max 43 deg C ( 110 F ). I believe the flash drive was getting heated up above 43 deg C. Do not know whether i received a defective one or else this model of flash drive works this way due to its lean thickness.
A separate HP flash drive which i had purchased more than 4 years ago (HP 64GB X705 USB 3.0 ) has a write speed of 50MB/sec much higher than this model and it is not getting heated up excessively as of date. This model is currently not available.
