I'm building a server that needs about 200G of harddisk space and the data has to be safe. If I need to replace a faulty hd and get downtime that's fine. Speed is not an issue. The system will boot of a scsi HD, I have a backup boot disk available. Disks (couple of 120G IDE or something) will be in 1+0, raid5 or raid6 (does software raid do raid6?) Is there any reason to use hardware-raid over software-raid in this case? thanks. Tinus.
