The host computer has 2x Intel Xeon 4C 2.40ghz CPU and 32 GB ram.
Operating system is Win 2008 R2 SP1.
MSSQL is installed on the same system disk as the OS.
The system disk is a virtual volume comprising 4x 10K 6Gbps SAS disks configured as RAID 5.
All system database files are located on this volume.
A second volume is made up of a RAID 10 array of 12x 15K 6Gbps SAS disks.
User database files are stored on the second volume.
Under consideration is moving all system database files over to the second volume.
Question - would performance advantage (ceteris paribus) be significant enough to justify it?
Would appreciate very much some Experts comments.
