What raid configuration is best for a FoxPro database?

My ERP program is written in Foxpro and it dawned on me that the RAID configuration may affect performance of the database. Are there any special considerations when hosting a Foxpro database on a server?

Approximately 100 users
Database size 4.2 GB

I have to agree RAID 10 is fast and reliable (and the most expensive variant). RAID 5 is reliable but slow on writes. RAID 0 is fast but not reliable at all.

An important information is the application architecture and topology. How do you access your app and data?

You may use the server just as a file server, you may use terminal services, you may create a COM object for each user on the server etc.

Also temporary files location can affect the application speed.
