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???
