With that statement above in bold, should I use my Raptor 150 RAID 0 with four partitions and then use the Seagate Barracuda for the fourth scratch disks? Am I reading this right?
Windows virtual memory and Photoshop scratch disk files
Virtual memory allows your system to use hard-disk space to store information normally stored in memory (RAM). Because it takes longer to access information on a hard disk than it does to access information in memory, using a portion of the hard disk as virtual memory can decrease performance. In addition, Photoshop cannot use the hard-disk space the system uses for virtual memory for its scratch disk files, which it uses to store image information as you work. If you need more memory to work in Photoshop, Adobe Systems recommends installing more RAM.
Specifying a fixed virtual memory setting helps prevent Photoshop scratch disk files from competing for the same space with virtual memory, especially if you set the virtual memory setting on a different drive than the primary scratch disk. For both kinds of virtual memory, be sure to use a drive with enough free, uncompressed space. RAID 0 partitions provide the best possible performance as Photoshop scratch disks.
