My new external HDD (WD My Passport 2TB, USB powered) benched 34/27 MB/s read/write out of the box. I then installed Intel Rapid Storage Technology driver and suddenly i got 110/110 MB/s.
But when i pul out the harddisk for some time, maybe after a restart of the computer, the speed is slow again!
If i rerun the IRST install i have high speed again.
How do i get high speed all the time?
