I am not familiar with the LSI cards, but with older 3ware and the 
ARECA cards, the raid sets when in any sort of redundancy mode must 
initialize in the background before normal use.  Until that is 
complete, performance is seriously slow.  Is the LSI doing that, and 
perhaps just not telling you ?
