Hello everyone,

I use the linux soft raid md driver on my system and I would like to make
sure I get the best from my hardware.

The board is an Asus P4C800-E Deluxe with ...

2x 74GB SATA WD Raptor 10000 on the Intel ICH5-R SATA controller (IDE
mode) :

/dev/md1 (raid1) -> /boot
/dev/md2 (raid0) -> /
/dev/md3 (raid0) -> /home

2x 120B SATA Seagate Barracuda 7200.7 on the Promise PDC20378 (IDE mode)

/dev/md4 (raid0) -> /mnt/data

What should I check and/or do (hdparm options, etc.) in order to
really optimize disks/raid performances on this FC2 workstation?

Many thanks for your time and help :)
