for RAID1, kernel software RAID is just as good as hardware. modern CPUs are a _lot_ more powerful than what you find on the cheap RAID1-cards, and the overhead isn't noticeable. another upside, with software RAID1 you can unplug any of the drives, install it on another system without having to think about RAID controllers and mount the drive. that last part is the reason we chose software RAID1 for the servers that have it here. RAID0 and RAID5 are different beasts though. -- Terje -- [EMAIL PROTECTED] mailing list
