OK So if i understand correctly, i should use software raid and not onboard chipset raids. I should also not put the entire thing on raid5 but rather raid1 for OS with one spare partition, and raid 5 for data. Is raid 5 really worth the effort with SATA software raid? Or should i just use raid 1 all around.... Will the boot loader recognize a raid 1 root partition or will it give me trouble? -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
