My main goal is to have Vmware running 25+ Virtual Machines at the same time without lag. I have 2 X W5580's CPU's with 24GB of ram and Adaptec 5408 RAID Card, and 4 P128 SSD's drives. The VM's don't need more then 8GB of hard drive space. Is it better to run 4 SSD's at RAID0 or 2 RAID0's and split where the VM's are?
