Currently i am getting the below mentioned average speeds while tranferring (Writing) a big video file of 2GB by using SanDisk ultra Usb 3.0 16 GB on WIndows 7 64 Bit on Lenovo B590 Laptop :-

Usb3.0 Driver Name :-Intel® USB 3.0 eXtensible Host Controller Driver
on Usb 2.0 port :- 14MBps
on Usb 3.0 port :- 22MBps
Ram : -2GB DDR3
Processor :- Intel core i3

No Copying tool like teracopy or copyhandler used

used Windows Default copying Mechanism

Also getting speed drops From 100Mbps to 22 Mbps on Usb3.0 port

No change occurred even after Changing the Drive Policy

Does Bios settings need a change?

Is the Windows 7 file copy dialog bugged?
