Teamsite 6.7.1 Hardware (disk) configuration

System

We are currently investigating upgrading our current Teamsite environment (6.5 SP3 on Windows 2003) to Windows 2003 and TS 6.7.1 SP1. We are going to be requesting a new server for this environment and noticed in the Teamsite Installation Guide that it is recommended to configure your disk for 0+1.

I have found some documentation about Raid 0+1 that makes it great for performance but not so good with reliabilty. However Raid 10 shows the same performance boost and better reliability than Raid 0+1.

Our current store is 170G in size so I am trying to find a solution that is reliable as well as fast. Are there any other recommendations or real life practices that seem to work well for disk configurations?

We know we have a store management issue like archiving, etc. But cannot address that at this time as appears cheaper to keep throwing disk at the environment.
