After reading reading the "Environmental and shipping specifications for LTO tape cartridges" [1] I came to the conclusion that tapes are not that great.
Environmental Allowable Recommended
Factor Storage Storage
Temperature 16 to 32°C 16 to 25°C
(61 to 90°F) (61 to 77°F)
In the summer it's not unusual to reach temperatures over 30°C in the house.
There's also this story [2]:
> I had a room full of servers, many with 16-36 disks per server and had an AC failure. Things turned off as planned, but it hit 115°F [46°C] for a bit. None of the disks died, majority of the tapes did.
