Extreme Pro USB 128gb Write very Slowly

Hi, everybody i’ve purchased  2 weeks ago 2  extrem pro 128gb USB

i have used only 1  daily basis  and now the maximum writing speed doesn’t exceed 80MB/s

and this speed  is slowing down to 30MB/s    and sometimes no faster than 15mb/s

and that with files (videos) not unlimited small files copy.

what’s the matter  the usb stick got only 2 weeks

2nd point  the usb stick  is very very HOT,  i thought was the temperature that slowing down the write speed and

put a fan to cool it   but   still  slow writing.

and i noticed that between many files serial copy  there’s like a moment the copy get stuck

also the size of the usb stick in explorer disappear and  re appear

sounds to me like the stick dead.

i have  a sandisk Ultra 128gb  that working very better  (faster tha the extreme pro!!!) and has been used  for a year now  and no probem

is there something i can do or do i have to send it back ?

thanx for your help
