What is the advantage that you think a separate partition will bring today when there is much disk activity? I grant you might be thinking of disadvantages of MacOS HFS, rather than the HFS+ (aka "extended format") that is used since MacOS 8.1. The activity is all on the same physical platter remember, no matter how many partitions you have. RAID-1 has no negative impact on performance (writes are in parallel to separate drives), and makes your data highly available. The advantage of a journalled file system is fast recovery in the event of a crash. > About organization -- what's wrong with that? If it helps you work better, then do it. Sure, but don't think you're getting something extra out of it. Multiple partitions add nothing to the system originally described, Peter
