Ah that's a valid reason :) RAID-5 is reasonable with disks under 1TB and arrays up to 6 TB. Further it's a bet against the law of physics :) However, a reliable RAID-5 is probably safer than an experimental RAID-6 overall :) -- = ------------------------------------------------------------------------ Emmanuel Florac | Direction technique | Intellique | | +33 1 78 94 84 02 ------------------------------------------------------------------------ _______________________________________________ xfs mailing list xfs@oss.sgi.com http://oss.sgi.com/mailman/listinfo/xfs
