Normally the best values are probed at boot up automatically. So no
manual adjustment with hdparm parameters are necessary. If you like to
play - and from your RAID0 setup it seems you don't care much about data
loss - you can try "EIDE_32BIT=3", "MULTIPLE_IO=16", "LOOKAHEAD=1". It
depends on your specific system whether these settings are already
active. Set the settings in /etc/sysconfig/harddisks when proofed to be
good. Take the warning at top of this file serious!
