Hi,
I have two disks
One is connected on primary IDE is speedier than the second disk on
secondary !

my PC, is Medion 1800+ AMD XP1800

I have 2 Chanals IDE and 2 disks both in UDMAMode 5

I used HD_Speed to test the speed of the two disks
In Burst mode , primary the disk = IBM 40Gb, ? Mb cache => got
60mb/s
,secondary the disk = Hitachi 120 Gb, 8 Mb cache => got 80mb/s

In read Acces ( non Burst ) the primaire = 25Mb/s with blocks 32Kb and
64Kb
the secondary 25Mb/s and then fel down to
several Kb/s then after 30s go to 12 Mb/s

Is there any body who could have an explanation of that strange thing ?
Why there is a drop in performance
is there sm tricks ? something to fix that performance.?
Thanks by advance

See nothing strange about it. The figures dramatically demonstrated the
difference between burst speed and throughput speed of both hard drives.
Throughput speed is what's important for speed of the OS and applications.
The second is good for storage, not OS installed usage.

You should do a write test of the same, not just read test.
