This from the TASCAM website: Although it doesn't say what type of array to setup. I use raid 0 for the instruments; with backup on another drive.
How about the ultimate GS3 system? What if I want to get crazy polyphony and multiple GigaPulse instances?
The limiting factor for polyphony is hard drive speed, so you'll get the best performance with a RAID array for your drives. The below system was tested with over 600 voices of polyphony (using 16-bit samples), of course your mileage may vary.
• Windows XP SP1
• P4 3GHz or faster
• 2GB RAM
• DVD-ROM drive
• 1024 x 768 monitor resolution
• Two-drive RAID using 10,000 RPM SATA drives
• MIDI interface
• GSIF 2-compatible sound card or ReWire-compatible host application top
