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 :) Gabriel
