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?
rrob - You mentioned using Vmware running 25+ Virtual Machines. Have you checked over in the business enterprise side of the ssd market? A few months ago I ran across some very interesting articles about VMware and ssd's.
