Already tried this, but it doesn't help
The actual settings (same on /dev/hdc):
bash-2.04# hdparm /dev/hda
/dev/hda:
multcount= 16 (on)
I/O support = 1 (32-bit)
unmaskirq= 1 (on)

hdparm -tT simultanous on /dev/hda3 and /dev/hdc3:
/dev/hda3:

Try 'hdparm -tT' with simultaneous /dev/hda3 and /dev/hdc3. This gives you
a baseline on the actual partitions involved.

Good idea!
The performance is only ~11MB/sec per disk
There is a bottleneck somewhere...

This is my raidtab file:
raiddev /dev/md0
raid-level
Hi,
I've successfully set up SW-RAID0 with Kernel 2.4.3 and Raidtools 0.9.
I did this to increase the performance of my HD, but nothig happens.
The hdparm results:
hdparm -t /dev/md0 : 20.25 MB/sec
hdparm -t /dev/hda : 20.51 MB/sec
hdaprm -t /dev/hdc : 20.71 MB/sec
I thougt the performnace of RAI
