Scratch disk performance raid 0 Vs single Hdd

I'm looking for the way to speed up the heavy disk-swap operation performed by CS when managing very large images ( > 32K).

Currently I use a 4Gb Dual Cpu machine running XP-Pro with two IDE ATA100 Hdd's. The scratch disk is set on the second Hdd.

Since there is an onboard Silicon Image sata controller with raid 0 and 1 capability, I've in mind to activate and use it with two 120gb sata hdd's in raid 0 for scratch disk I/O.

Your feedback about performance boost using CS + raid 0 systems Vs. single Hdd, is really welcomed.

Thanks in advance

Yesterday evening I've installed and configured a two hdd (120gb) raid0 sata system. The performance boost are really incredible, typically 50% faster than before.

If you are involved in very large images management with heavy disk swap, I strongly suggest this cheap (~190Eur) way.
