Interesting point but not likely to happen. I run 3 Windows VMs all day, most of which are doing numerical calculations and not a huge amount of IO in the Windows environment itself. In my usage model the 12 cores get a workout nearly every day. > >> 1 SDD - 120GB SATA3 on it's own controller >> 5+ HDD - WD5002ABYS RAID Edition 3 SATA3 drives using Intel integrated >> controllers >> > > Again, if you're serious about RAID, get an LSI MegaRAID card.

Will consider, at least in the long run, if this thread & work doesn't yield significantly improved results over the next few weeks. > Oh, and don't believe all the published numbers on drives, > etc...benchmarking is an art. > > Bob Absolutely! :-) Thanks, Mark
