What I initially ignored was the cost of a "library" (robot), which is, arguably, necessary if the minimum time to write a tape is over 9 hours (longer than a standard workday, meaning 1PB could take 17 workweeks to write with a single drive with no robot).
Including a library to hold all 84 cartridges might be tricky, but it appears there are 80-slot ones in the $12k range, which brings the total tape price up to $29k and reduces the write time to under 5 weeks.
Alternatively, one could just buy multiple tape drives and no robot. $25k gets faster write time than above.
