Title: Redo Logs - Raid 1 or No Raid

Hello all

Oracle 8.1.7
Windoze 2000
Archive Mode - OLTP System

Which do you think is a better set up for the Redo Logs:
 2 Groups on  2 Raid1 or 4 Groups on  4 separate non-raid disks?
Granted you gain fault tolerance with the mirriored pair, but is that really needed if you multiplex group members over 4 different disks?

As usual we are working with clients that have limited number of disks to work,  so  4 Raid1's is not an option ;) 

Does anyone  have multiple log groups on the same physical drive(s). For example,  4 log groups,  2 members  each,  with group

1&3 on drive A, and 2&4 on drive B? Does this really gain you anything?

Any ideas and comments are welcome. Thanks for all the help.
