For what it is worth, in our case we have a couple of instances that are about 150G each. What we have done is used RAID5 SCSI adaptors such that the primary tablespace drives are 100+GB. On one platform the disks are:

         A/B(floppy)
          C  System, 4GB, mirrored
          D  CD ROM
          E  DBA drive,8GB, mirrored
          F  User Staging,8GB,mirrored
          G  128GB, RAID5

The instance is a quad processor with 1GB of main memory, running O8.0.5 oen NT4SP3.

We have a server set with raw devices, but it is a Parallel Server (for 7x24 failover) configuration under IBM AIX. To tell the truth, I haven't heard of anyone using raw devices under NT.

some witty phrase goes here, I think.
