CCL:G: does a raid improve the performance of gaussian for windows?

 Hello,
 first of all, I have no experience with your planned configuration
 (gaussian, windows and intel), but I have got some experience in using
 gaussian on amd linux cluster. So, the followings are just thoughts:
 I would check the price/performance ratio of both intel-dual-core and
 amd-opteron-dual-core. (Last time, amd was better.)
 Considering raid, your gaussian scratch partition should be a raid 0
 disk (two identical scsi or sata or ide drives - striping). This means
 optimally you need at least 3 disks 1 for the system and 2 for the raid.
 There is no redundancy at this raid level, but there is no need for
 that. What you need is speed. Taking into consideration the low price of
 hard disks, probably it is worth its price and you get improved
 performance.
 By the way, the hardware raid solution should be better for you.
 Best wishes,
 Jozsef

 worth spending the money in two disks? what kind of raid should this be?
