"You will get 2 parallel sequential reads at around 120MB/sec
assuming you're not bus limited."

To clarify because this looks ambiguous to me now, you should be able to
perform 2 parallel sequential reads both at 60MB/sec = 120MB/sec total.

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
