No, it's just that you shouldn't use an NT server. :-)
Without the OS bigotry - RAID-5 gives poor write performance, particularly for database access patterns. Oracle will work on RAID-5, but it's a bad idea from a performance aspect to put any tables, or other objects, that will be frequently written to on a RAID-5 storage array.
If you have a large amount of data that's read-only, or only updated infrequently, then RAID-5 offers a good compromise between resilience, performance and cost.
