        I admin a server which runs Oracle 6 with 20GB of RAID 5 disk arrays. Performance with the RAID arrays has not been an issue at all - but it all depends upon how your database will be accessed. If the majority of access will be READING then you may actually see a performance boost over standard disks. Writing may be a little slower.

        As for 'security' I assume you mean, how well is the data protected from failure, not from 'hackers'. I've lost up to two disks in an array without losing a single bit of data. The database just kept cruising along. :)
