Thanks for replying MacTroll.
The reason I didn’t want to go with a Raid 5 is b/c the write speed isn’t very good and we will be dropping a lot of files on the server everyday. Plus, what’s the point of doing a Raid 5 on a xServe with only 3 drives? Isn’t the point to have 4 drives (1 spare) so if a drive in the raid fails the spare kicks in?
We have a gigabit network at the office and its FAST. So I wanted to make complete use out of it. Also, we want to mirror the boot drive, not stripe. Then the externals would provide the backups. However, what I really need to know is if home directories and shared data on a single mirrored volume will be slow or if it needs to reside on a single standalone drive. Again, data from that will be backed up incrementally to rotating firewire disks for backup. There has to be somebody out there who does a setup similar to this or does everyone use a xServe RAID for shared data and home directories?
