This topic is quite interresting. I found some information about raid5e and raid5ee only on the german wikipedia, but the pictures could do just fine. http://de.wikipedia.org/wiki/RAID#RAID_5E http://de.wikipedia.org/wiki/Bild:RAID_5E.png http://de.wikipedia.org/wiki/Bild:RAID_5EE.png as i understand it, there is no real raid5 in place. raid5ee is basically a simple raid5 with 4 discs, but leaving the 4. disk virtually empty. so if 1 disk fails, the empty stripes are filled. i dont know much about this topic, and i dont know if the information in wikipedia is correct, but i hope i could help a bit yours stephan -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!
