Is it possible with MP & OsX / BSD? I have 5 disks in my MP: 1. raid1 pair of disks for system 2. raid0 for video cache 3. single disk for general scratch I'd like to have some redundancy with video cache without sacrificing all speed. So, would it be possible to have 3-disk raid1E for video cache? (Yes, I will buy external raid enclosure for raid10 in the future, but not just now. And it is interesting to know system's soft/hardware limits...) Anybody heard anything about new raid levels in SnowLeopard?
