Because I have to use 10.2.8 because of Projectbuilder WO in the foreseeable future and because you can not parititon the Apple Software RAID. And thirdly, because you can only put two harddisks in a G5 I have decided to de-RAID my setup.
I have some hopes that my textutils-2.1 benchmark from a few days back will perform better on an UFS partition.
