I did not see any way to choose the strip and cluster sizes while creating the array, so they are at the default. I may be able to see what the defaults were by running the raid array utility in windows.

My guess is that adding memory/battery or changing to a P800 card will help, and I am testing that guess buy purchasing both (on order, not here yet). If someone tells me that card XXX will fix all my problems I would probably order one of those. I have had good luck with 3ware SATA raid cards, but I'm not sure I could use them with the HP DL380 internal drive slots because of the cabling used.

So, in other words, you have absolutely no basis for thinking that it can perform as desired, other than a vague hope that Intel and HP are real nice guys who never do anything wrong. I've got a Dell PowerEdge 2500 with a "PERC 3" RAID controller, which is based on an Adaptec chipset. Normally, I really like Adaptec's stuff, and Dell's PERC cards, but this one sucks monkey balls. Performance absolutely blows. Turns out this card just sucks. Dell/Adaptec turned in a stinker. I've even had Dell's tech guys say this. The only solution is to use a different card. Every company on Earth turns out crap sometimes. You may have encountered one of those times. You either have assurance that it works as you desire, or you don't. So far, you have no such assurances. Get some specs and stop guessing. Or, go right on guessing and hoping, if that's what you want. I assumed you were posting because you needed help. I've identified what you need to do. It's not my job to make sure you like it. Not at the rates you're paying me. -- Ben ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~
