Loss of speed

Tested speed on two WD portables and they were exactly as in their info average 85MB/s and 60MB/s.

But then after wiping system drive and installing windows 7 their average is only 20-25MB/s???

All drivers are updated except 3 bluetooth drivers, which were impossible to find for windows 7, and these driverless units are “BCM20702A0”, “PCI Device” and "Universal Serial Bus (USB) Controller

But there isn´t any bluetooth devices in use so???

Hello,

Please make sure you have the latest updates for your USB 3.0 drivers.
