In RAID-0? Let's hope so :o) However, I would rather use "better" instead
of "fixed". Another solution would be to allow just one parallel job, I'm
not sure about your expectations in this way.

The question is: Do you really need a tape solution? Isn't better for you
to start with disk based solution? For example, some HW RAID card with
8 or 16 internal ports (~ 300 or 500 EUR) with some 2-6 TB HDDs? And you
can reuse them after. Tape solutions are very interesting, but they usually
count with great number of tape media or with archival purposes or data
exchange.
