SVDL - You've answered a significant portion of my questions, in the Hardware/Technical Forum, so I guess you'd know; but I'm surprised installing WIndows/Poser, onto a RAID-0 array, would'nt be the much help?  Allthough I do see what you mean about just having enough RAM...

Pakled - As far as I know there are only 3 types of RAID.  RAID-1 is the use of two disk, to da all of the same things, so incase one dies, the otehr still has all your memory.  This is only like half as fast, so people developed a way for you to use 4 disks at once, where the second two disks are only for speeding up the process.  That would be RAID 0+1(or 1+0?)  Then the spped emons cam along and threw the RAID-1 part, of the RAID-0+1, out the window.  This leaves you with RAID-0, which would(.../me looks around for where SVDL would have used RAID-0...8 ^ o...) just be faster....Allthough RAID-0 is also known as a Fault Tolerant disk.  Becasue it was originally made to support a very stable RAID-1 array, the is a measure of risk involved with running on only RAID-0, in other words when/if it crashes do'nt be too surprised ;  ).
