My System Specs


This looks like the low-end LSI cards, it likely does not have hardware XOR ("RAID Engine") so RAID5 is always going to have terrible write speeds. It also lacks any onboard cache as well. This is a HBA product rather than a ROC product.

I would suggest doing RAID10 instead and just suck up some of the storage loss. You'll get the performance at least. Otherwise, look into buying a proper RAID controller.

My only other thought, was the array fully initialized? That should take a couple days at your capacity.
