The cost of making a safe that will withstand more than 60 minutes burning versus the number of fires that do last over 60 minutes doesn't make it viable.
60 minutes is typically fine.
if you put one of them inside another one, does that give 120 mins resistance?
I have one of these
I feel more at ease knowing my important documents/media are safe from fire and water, however if you want a burglar proof safe then look elsewhere
That is something I would suggest rather than a safe, unless you have the secret forumla to coca-cola on those dvds I really don't think you need to worry about theft.
18 years of hard work in the business which i now own, our entire database of customers and everythign associated to rebuild the company from anywhere.....yes, its pretty crucial and would have a value if stolen (even by oppertunistic thief) as the personal data is very useful.
