Does RAID 5 contradict and minimize the benefit of OFA on NT?

Hello:

I am working on Oracle 8.0.5 application on NT 4.0. We are in the process of setting up a user acceptance server and a development server and have the luxury of having as many disk servers as needed on each respective server(within reason).

I am thinking of going with a configuration of drives consisting of the following:

1. Oracle executibles, redo log group members, control file, system tablespace
2. data files, user files, control file, redo log members
3. index files, control file, redo log members
4. rollback segments, export files, backup files
5. archive log files.

Hopefully this configuration will be with physically separate drives and more than one controller If these are logically partitioned drives, I believe it will still depend on how many physical drives and controllers are involved. THanks.

However, I have been told that RAID 5 will reduce or contradict the ebenfits purportedly gained from the multiple disk drive/OFA configuration.

1. Has any one found this to be true?
2. Will the benefit of RAID 5 -- faster reads versus slower writes -- for a transactonal database still apply?
3. Has any one seen Oracle position on the value OFA versus the benefit of RAID 5?
4. Any other information concerning this situation will be greatly appreciated.

Thanks.
