I am saving up some cash for a future upgrade to a either Z800 or a Z600, perhaps if the circumstances allow a Z420 with Xeon HC (6 core) cpu which already has a 6 Gbps SATA interface in comparison to the current 3 Gbps SATA interface of my current XW6600.
I am considering a raid 0 solution Captain WD but i am primarily interested in faster boot loading and faster program loading.
Just investing an LSI or Adaptec card that will not run on later Workstation is n ot a prudent way I reckon.
