|You don't have to pick LTO-7 you know. LTO-3's are still in common use, and they came out in 2005. If it were me, I'd probably look at LTO-6 drives instead. That'd offset the cost in the SAS controller you'd need to buy, but forgot to factor in to your calculations. |
From the sound of it, you've already did the price to GB comparison, and you've decided your volume isn't high enough to offset the initial cost. So it comes down to if the 15-30 year data lifetime is worth the added cost, and that's something you need to answer yourself. Personally, I wouldn't expect any data on an unplugged HDD to survive 10 years, but feel free to get back to me at that time, and we can go over your failure rate.
