Sometimes its easier and faster to throw hardware at a performance issue
but as a rule, application, database, and OS tuning should occur before
making your reseller happy. Even if disks are overly busy, it may be a
sign of poor app design or index management more than insufficient disk
performance.

Mike,
With 15% Disk utilization, maybe your best $ value is i Series Nav index
advisor.
Seems you are currently "running from memory" primarily and a few
well-placed
indexes could give good results on any "slow" jobs/reports

Has anyone moved to using SSD drives and if so have you seen any
significant performance improvement by doing so? We are not in need of
additional space (running about 50%) and disk utilization (% busy) is not
extremely high (10-15%). Wondering if a plan to migrate to SSD would be
worthwhile.
