Hi,
Unfortunatelly it is not the case. Please go to my original e-mail. I've
ran two simultaneous tests and I get:
hdparm -t /dev/md6 &
hdparm -t /dev/md6
This is the result:
--disk/hdg----disk/hde-
_read write _read write
0 0 : 0 0
0 0 : 0 0
124k 0 :26.0M 0
368k 0 :45.5M 0
0 0 : 0 0
0 0 : 896k 0
124k 0 :1568k 0
0 0 : 0 0
One disk works with 75% of its full speed, the second one works with
0,6% of its full speed or even less.
Best regards, Janusz
