I may be kicked off this list for making this comment...but I would look into a simple Hadoop cluster to store the data...I am not sure if your data is written once and done - or if you update it frequently, but there is a lot to be said for the cost/TB and the ability to store data long term in a Hadoop cluster.

And don't forget about compatibility. For example, an LTO-3 tape written 7 years ago won't be able to be read on an LTO-6 drive -- a very plausible timeline example.
