your card - 6/iR - don't have RAID 5 and RAID 6 levels !
this is "full" PERC 6/i:
Why doesn't the card have a heatsink? Is it due to the fact it isn't a full blown PERC 6, or should it have one and I need to get one installed?
Is a BBU really necessary for raid 0, or is that dependent on the write setting still?
