I meant chemical engineering. Not versed in all the acronyms, I apologize.

Despite the commonly believed myths, tapes are not very durable unless you store them in the right temperature and humidity and the right orientation. And .. what do you know, the same holds true for magnetic drives (with slightly different, though no harder to achieve, environmental conditions).

Tapes are also generally more expensive before the 200TB mark or so these days (you did factor the cost of a drive into your cost saving, did you?) and actually around 400TB if you factor in two drives (which you should, because the tape drive also fails).

Trusting an SSD is stupid. But the economics of backup tapes are very different from what the vast majority of people believe. For 99.9% of the situations, backing up to a magnetic drive is a better solution.
