Help me choose a RAID level combination for a SQL Server 2008 instance
I vote for option 1. Bear in mind that RAID 0 means "no protection" - do your logs matter? (yes they do).

It also has the benefit of simplicity

The SQL Server docs say:


  For optimized I/O parallelism, use 64 KB or 256 KB stripe size.


But it is usually good to go with the controller default IMO
