LOL, I don't want to be in the position of continuous upgrades due to
insufficient planning / forethought.
However, I will concede a tendency toward massive overkill during planning.

I couple years ago I had to plan a project that would require 1TB of
storage over its lifetime.
The original plan was a $15,000 NetApp device.
When implemented it was a < $800 HP wx8400 Workstation with dual 500G
SAS drives.

That,s why it is a long range plan.

I think I'd have bigger problems right then.

A Meinberg with GPS & WVV would be cool.
Something to do if I had the resources, but if I did, there would be
things more important to do.

I'm very impressed with the quality of the answers received in this group.
Thank you all, very much.
