It feels like there is something fishy going on.
Maybe the RAID 10
implementation on the PERC/6e is crap?


It's possible. We had a bunch of perc/5i SAS raid cards in our servers that performed quite well in Raid 5 but were shite in Raid 10. I switched them out for Adaptec 5808s and saw a massive improvement in Raid 10.
I suspected that. Maybe I should just put the PERC/6 cards in JBOD mode and then make a RAID10 with linux software raid MD?
