Hi folks,

I have two options:
3*18 GB 10,000 RPM Ultra160 Dual Channel SCSI  controller + H/W Raid 5
and 
2*36 GB 15,000 RPM Ultra320 Dual Channel SCSI and no RAID

Does anyone opinions *performance wise*  the pros and cons of above 
two options.

please take in consideration in latter case its higher RPM and better
SCSI interface. 



Regds
Mallah.
