You might want to evaluate the performance you can achieve with a single-SSD

solution.
Again I bet it depends on the application but our experience with the older
Intel 710 series is that their performance out-runs the CPU, at least under
our PG workload.
How many people are using a single enterprise grade SSD for production
without RAID? I've had a few consumer grade SSDs brick themselves -
but are the enterprise grade SSDs, like the new Intel S3700 which you
can get in sizes up to 800GB, reliable enough to run as a single drive
without RAID1? The performance of one is definitely good enough for
most medium sized workloads without the complexity of a BBU RAID and
multiple spinning disks...
