The HDD's _was_ mounted very tight and stable, so the FAN vibration is propagated to HDD without the problems, next the internal accelerometer founds this vibration and lowers all the HDD operations ! If I get out the HDD from the case and mechanically isolate it from the FAN vibration the speed momentally grows to the max value ! > And the WD ones don't have a problem with the vibrations? The desktop WD do not have this issue as it has much more mass than mobile one. As you can see by tests made by me - the mobile WD behaves nearly same as Hitachi one - it lowers the HDD operations by -20Mb/s value. > Wow!
