I agree here with Christopher; A SSD to handle the high IOPS requirements
of real time data logging; combined with a scheduled transfer which can
"move" the stored data in a linear large block copy operation to ordinary
spindles, would be a cost effective hybrid solution.

This of course is assuming the application can handle this separation of
data; and I know nothing about Nfsen

Since netflow processing is generally I/O bound, you may want to invest
in
15K drives.

I had suggested off-list that perhaps primary storage as SSD was a
better path, is there a reason to not do that? (with some larger
storage on spinning-media for historical storage/query).
