Well, if you are going to making one arrray of 9 drives, write performance will bad. If you are going to making 3 arrays of 3 drives each, you will end up with a lot of overhead. RAID5 arrays of 5 drives is kinda of nice sweet spot. If you go much bigger, just use RAID0 over multiple RAID5. 10 drives is a much nicer number. > > with 10 drives instead, and make two 5 drive arrays. > > > > Tom > _ ______________________________________________________________________ > | / o / / _ Bulte email: wilko @ yedi.iaf.nl http://www.tcja.nl/~wilko > |/|/ / / /( (_) Arnhem, The Netherlands - Do, or do not.
